Lists of frequently asked questions

You can find user manual files on the page http://download.drweb.com/doc. They contain a sufficient level of detail on how to use Dr.Web. We first recommend that you study the user manual. It is quite possible that you'll find the answer to your question there. Also, users who are just getting familiar with our program can look for the answer to their question in the section Frequently Asked Questions.

Of course, it is a good idea to test how the program operates on your computer before buying it. Doctor Web offers its prospective customers an opportunity to evaluate a Dr.Web anti-virus for 30 days, once in 4 months. Availability of all features in the demo mode is a huge advantage of Dr.Web: it detects malware and provides curing just as well as commercial Dr.Web products, time of use is the only limitation.

If you are going to to protect your Windows or Linux PC or Mac with Dr.Web, download the distribution, install and register the software (Internet connection is required). In the License Key file step, select Receive Key file during installation and a key file with validity of 30 days will be automatically downloaded and installed on your computer.

To evaluate corporate Dr.Web solutions, use the web-form to request a demo key.

Yes, you can. A demo version has no functional limitations. You can update the database as scheduled, or manually.

Removing the program from your computer is not necessary. To turn a trial copy of Dr.Web into a licensed version, you need to purchase a license and register it. Right click on the Dr.Web icon in the system tray and select Register in the context menu. During registration you will need to choose the option Obtain a license key file with serial number. Once you have entered your serial number, a key file will be downloaded to your computer automatically. An Internet connection is required for registration.

A Dr.Web anti-virus with a 30-day demo key functionally is no different from a similar product with a license key (except for its time of use). Thus, the installed Dr.Web anti-virus demo provides protection from all types of malicious software.

The 40% renewal discount is only available to users of three-month Dr.Web trial licenses.

The discount does not apply to 30-day trials. To continue using Dr.Web after the 30-day trial period, users must purchase a standard new license (not a renewal license).

If you represent an organization, submit a demo key request through the form on our web-site. If you need keys for Dr.Web for Windows and Dr.Web Security Space, then you need to request a demo for Dr.Web Enterprise Suite. Select the agent.key from the acquired set of keys to activate Dr.Web for Windows and Dr.Web Security Space.

If you are a home user, you must connect to the Internet and obbtain a key from our web-site.

Note: You can't port a demo key to another PC, the anti-virus won't work with the key file on another computer.

If you already have purchased the serial number, you can ignore such messages If you don't want to receive such reminders, follow these steps:
Right-click on the Dr.Web icon in the notification area. In the context menu, select Tools–> License Manager. In the License Manager you need to remove the demo license (key file drwdemo.key) and reboot the computer.

This message means that the thirty day trial period is over. You need to either remove the anti-virus, or purchase a licensed version of Dr.Web.

No. In order to migrate to Dr.Web anti-virus at a discount provided under this programme, you need a commercial license for a different anti-virus. Find out more about the "Switch to the green!" programme here.

All products developed by Doctor Web come with comprehensive user manuals. To download a manual for the anti-virus installed on your PC, look for the product’s description in the Download section of www.drweb.com. Open a corresponding page and download the manual from the Documentation section.

If you can't find an answer to your question in the documentation, please go to the Frequently asked questions section or contact the Technical Support service.

If you already have registered your serial number, do the following:

Right-click on the Dr.Web icon in the notification area. In the context menu, select Tools–> License Manager. In the License Manager you need to remove the demo license (key file drwdemo.key) and reboot the computer.

The two versions differ only by their time of use — a demo version works only for 30 days. There are no other differences between the demo and licensed versions of Dr.Web, because we believe that any limitation in the operation of the anti-virus will prevent a new user from making their own opinion about the product.

A demo version is a full version of the anti-virus that will be operational for 30 days. There are no other restrictions on its use.

A beta version is a preliminary released, not yet officially available for sale version of the program. Beta versions are created to allow users (beta testers) to undertake extensive testing of the product which will enable developers to fix bugs before the program is released officially. Using a beta version always incurs a risk since errors in the program can make its operation unstable or cause system errors.

We can only tell you for sure after you provide our technical support engineers with several samples of the encrypted files. Unfortunately, the probability of successfully decrypting your files is only 10%. Find out more at https://antifraud.drweb.com/encryption_trojs/.

If at the moment of infection you had a valid commercial Dr.Web license and installed Dr.Web Security Space or Dr.Web Anti-virus for Windows (version 9+), or Dr.Web Enterprise Security Suite (version 6+), you are entitled to free decryption, if it is possible. You are welcome to file a request at https://support.drweb.com/new/free_unlocker/?keyno=&for_decode=1.

If your files are among those lucky 10% that can be decrypted, we'd like your data to stay secure from encryption ransomware in the future.

The proactive protection technologies for detecting and neutralising the latest and yet unknown threats, including encryption ransomware, are available in both products. However, the Data Loss Prevention module, which creates backups of files that are important to you and protects them, is only available in Dr.Web Security Space. That's why we recommend that you purchase a Dr.Web Security Space license. It costs just 10% more.

If your customer has a valid commercial Dr.Web license and at the moment of infection the system was protected with Dr.Web Security Space or Dr.Web Anti-virus (version 9+), or Dr.Web Enterprise Security Suite (version 6+), file a request for decryption at https://support.drweb.com/new/free_unlocker/?keyno=&for_decode=1.

Attach to your request the power of attorney that entitles you to represent the interests of the customer, as well as documents confirming that your customer is the legal owner of this license (a photo or a scanned copy of the license certificate, the payment receipt, an email from the online store or other confirming documents).

These are non-commercial licenses (they are not for sale) and, therefore, cannot be restored.

To continue using Dr.Web, purchase a commercial license in the Dr.Web eStore or from an authorized Doctor Web partner

  1. Log into My Dr.Web Portal—select the appropriate option from the menu of your Dr.Web application.

    Screen «My Dr.Web»

  2. Go to the ‘Licenses’ section, and in the ‘Blocked’ tab, select ‘Replace serial number’.

What happens next

A new serial number will be sent to the email address you specified when you registered the serial number.

IMPORTANT! If you no longer use this email address, contact Doctor Web's Technical Support Service to replace your license.

If your license has been blocked because of piracy, it means that you violated the terms of the license that enabled you to use the Dr.Web key you received when you registred your serial number. You have violated terms in clauses 5.1. and/or 5.3 of the Doctor Web software usage agreement you accepted when registering your Dr.Web serial number.

clause 5.1… The software can only be used within a specified period of time, under a defined operating system and with the number of protected objects specified in the license key file, and in accordance with other parameters specified in the file.

«п. 5.3... You can store no more than two backup copies of a license key file. You may not give these copies to a third party or place them on tangible media that is accessible to a third party or make the files accessible to the public over the Internet or by any other means. If a valid key file is found to be in the public domain, the Rights Holder is entitled to render a software copy non-operational and disable its features.

If you have already used the one-time option to restore a Dr.Web key file and wish to continue using Dr.Web, you need to renew or expand (if necessary) your blocked license — via the Dr.Web eStore or an authorized partner of Doctor Web.

In either case, you will get a renewal discount — starting at 40% for a one-year license.

Yes, you can. The key doesn't depend on an OS version.

Right-click on the Dr.Web icon in the system tray and select Tools–> License Manager. In the subsequent window you will see all the information about the current license, including its expiration date.

To register your serial number and obtain a license key file, you need to access the Internet. This can be done not only from the computer on which you installed Dr.Web, but also from any other PC connected to the Internet.

Go to the registration page Enter your serial number. If you are registering a license renewal, specify the serial number or the license key file of the previous license. Fill in the personal data fields. After registering on our website, you will be able to download the archive drweb32.zip which contains your license key file drweb32.key.

The required identifier (ID) is already imbedded in the code of the application installed on your workstation. You can find it in your Subscriber account area on your service supplier’s website. If you use Dr.Web via the SCC (you bought a subscription on Doctor Web's site), the subscription ID is located in the My subscriptions section.

  7. Upon completion of the registration, a new key file will be automatically downloaded and installed, and the registration wizard will display information about the license. Click Finish to complete the wizard.

We did that to protect the rights of legitimate license owners. Sometimes licenses get stolen — for example, when a computer is getting repaired at a service center. Some users publish their serial numbers on the Internet, or give them to their friends, thus violating the terms of the license agreement and making it possible for anyone to apply for a renewal discount. To protect the rights of the rightful license owner, part of the serial number is hidden in Dr.Web services. The entire serial number is only visible to the license owner:

  • in the email received from the Dr.Web eStore
  • on the license certificate.

Do not show these documents to anyone if you do not want to lose the privileges enjoyed by rightful license owners.

You can verify this in the License Manager (enter only the serial number, and do not fill in the email address field).

If the license is active, you can get full information about it in the License Manager (the list of software products and protection components for each product, the validity period, whether the license includes technical support services, and other useful information).

  • If you remember the wrong email address you used for registration, change the registration email on your own by using this service.
  • If you do not remember this address:
    1. Contact our technical support and provide documents confirming that you are the legal owner of this license (a photo or a scanned copy of the license certificate, the payment receipt, an email from the online store, or other confirming documents).
    2. Change the registration email on your own by using this service.
  1. Register your serial number again. An email containing the key file will be sent to your registered address. If you change this address, the email will be sent to your new address.
  2. Contact our technical support service. If you send a support request using an email address that differs from the one you used to register your license, our support expert will have to make sure that it is the license’s owner who has contacted the technical support service. They have the right to request a photo or scanned copy of the customer's license certificate, their license receipt, an email from the eStore containing the user’s name and email address, or other documents that may serve as confirmation. We hope you understand that if John Doe is the registered owner of a license, but John Smith asks us to restore the registered email address, we will reject such a request in accordance with current Russian legislation. For more about who the owner of a Dr.Web license is, read here.

IMPORTANT! Do not allow anyone to register your license using an email account that belongs to someone else and is inaccessible to you! If they do, you will not be able to use our services (for example, to make technical support requests as a Dr.Web commercial user) and get the benefits associated with license ownership, including the right to renew at a discount.

If that happened:

  • contact the store where you registered your license, and try to find out what email address was used; or
  • contact Doctor Web's technical support service. Our support expert will have to make sure that it is the license’s owner who has contacted the technical support service. Before contacting the support service, please prepare a photo or scanned copy of the license certificate, the license receipt, an email from the eStore, or other documents that may serve as confirmation. We hope you understand that if John Doe is the registered owner of a license, but John Smith asks us to restore the registered email address, we will reject such a request in accordance with current Russian legislation. For more about who the owner of a Dr.Web license is, read here.

IMPORTANT! After the technical support service provides you with the email address that was used to register your license, immediately use the service to change the registration email address, and register the license to your email address.

You are probably trying to renew a Dr.Web Security Space (Dr.Web Anti-virus) license, and purchased a Dr.Web box containing two serial numbers (or two licenses, each for one PC). When you were registering the first serial number from the box, you specified your old license’s serial number. As a result, you ended up with a new license whose term had 150 days added to it as a renewal bonus. Most likely, you tried to register the second serial number from the box and again specified the serial number from your old license. Since 150 days were already added to the term of your new license, Error 401 occurred when you tried to register the second serial number. Register the second serial number as a new license to which the renewal bonus does not apply.

Under the usage terms for a trial, you can only get a trial once a year. This error occurs if a user attempts to get another trial before an entire year has passed since their previous trial license expired.

This error occurs if a trial key file is transferred from one computer to another. This violates the usage terms of the trial.

  • If you need Dr.Web to protect a different computer, request a trial for that computer.
  • If you have already used your right to one trial per year per computer, and you wish to keep your system protected, purchase a Dr.Web license.

Register the serial number via our website. To add a key file to the anti-virus, follow the instructions found in the registration email you received.

IMPORTANT! To register Dr.Web serial numbers, always use an email address whose mailbox is accessible only to you. Doctor Web will be sending a key file with instructions on how to use it, and service messages about the status of your licenses to this address. You will need to use this address in order to contact our technical support service, get a renewal discount, and use the many other services available on our website.

Purchasing a licensed Dr.Web product has certain benefits:

  • The manufacturer is responsible for the operation of the software.
  • A company using legal software doesn’t violate any property or usage rights.
  • Guaranteed free technical support via the web-form.
  • Free updates of the Dr.Web virus database.
  • Free updates of Dr.Web software modules.
  • Free upgrade to a new version.
  • A license can be renewed at a discount.

A DrWeb license for one PC entitles a user to install and run the program simultaneously only on one PC. The number of installations and reinstallations is not limited.

In order to use the license on the new computer do the following:

  • copy the Dr.Web key file to a floppy disk or a flash drive;
  • download the distribution of Dr.Web anti-virus and install it on your new computer;
  • copy the Dr.Web key file from the floppy disk or a flash drive into the anti-virus installation directory;
  • remove Dr.Web anti-virus from your old machine.

You need one license. Dr.Web protect computers, not users. 1 license=1 PC

You need two licenses because both devices need to be protected.

Two licenses — one for each operating system (for each Dr.Web software product).

Two licenses — one for each operating system (for each Dr.Web software product)

10 licenses. 1 license = 1 PC

Regardless of which Dr.Web distribution was in the box you purchased, you can use the latest version of the anti-virus (as soon as you register your serial number on our website and receive a license key file). The latest distribution can be downloaded from our website: http://download.drweb.com.

If you haven't installed Dr.Web yet, just launch the downloaded file. During installation, enter your license’s serial number.

If the anti-virus is already installed, but you want to upgrade to the latest version, you should run the installer of the new version. When the installer detects an outdated version, it will remove it. After a system restart, the newly installed version of Dr.Web will start automatically.

Put the downloaded zip file in any folder other than the one in which you installed Dr.Web. Then right-click on the anti-virus icon (spider on green shield) in the system tray near the clock. Select ToolsLicense Manager.

Press Get new license → From file…; browse to the key's location. Click Open.

After you import the key, restart your computer.

Each of the serial numbers must have validity of three months or longer.

    #drweb

If two licenses are registered one after another for the same device:

  • The valid license will be blocked;
  • Doctor Web will add 150 days to the license you used for the renewal. And if you are renewing a license that hasn't expired yet, its remaining validity will be added to the new license period.

To get 150 extra days added to the term of your license, the following conditions must be met:

  • The validity period of the license you want to renew must be three months or longer. If the license has been blocked or renewed before, it can't be renewed.
  • To renew a license and get a bonus, you need to purchase a new license—one toward which no renewal discount has been applied. Its validity period must be 12 months or longer.

The second license can be registered either while the first license is still valid or after it has expired.

  1. Click on the Dr.Web spider icon in the notification area. In the pop-up menu select License.

    The menu that appears while the license is still valid

    The menu that appears after the license has expired

    If you previously registered a license and it is still valid, its serial number will appear in the License Manager.

    In the subsequent License Manager window click the Buy or activate new license button.

  2. The Registration Wizard dialogue will open. Enter a new serial number.

  3. In the next dialogue that opens, select I will specify the previous license.

    In the newly appeared window, enter the serial number or specify the location of the key file associated with the previous license.

    By default, you are prompted to enter the serial number, but you can also specify the key file's location.

  4. Fill out the registration form, and click Next.

  5. Press OK.

    The License Manager window will open.

Once you have registered a new serial number:

  • The license you are renewing will be blocked (since it has been renewed).
  • The new license will have its validity period increased by 150 days—this is how Doctor Web will reimburse you for the renewal discount you did not receive when you bought the new license.
  • If you renewed a license that hasn't expired yet, its remaining validity period will be added to the validity period of your new license.

Click on the green spider icon in the right corner of the taskbar. In the newly appeared window, click on License. In the Current license area, enter the number of the new license.

#drweb

Renewal discounts are unavailable for this product. To renew this product license (without a renewal discount), purchase a new license.
  1. Both valid and expired licenses can be renewed. There is no expiration date limitation for Dr.Web licenses subject to renewal.
  2. A renewal discount is provided only if the period of the previous license was/is at least six months in duration.
  3. A renewal discount is provided only if a license for a similar Dr.Web anti-virus for 1, 2, or 3 years is purchased.
  4. For Dr.Web Security Space and Dr.Web Anti-virus a renewal discount is provided for any number protected objects (from 1 to 5 inclusive).
  5. A renewal discount is provided for protected objects whose number is less than or equal to the number of protected objects covered by the previous license that is subject to renewal.
  6. To get a discount, a Dr.Web key file or a serial number must be provided (each such file or number can be submitted for renewal only once).
  7. To get a renewal discount, a customer must present a serial number or a key file (including OEM) to a salesperson.

The discount multiplier used depends on your customer category and the period of the license you want to buy. A multiplier is applied to the price of a 12-month license.

Customer type Discount condition Renewal
1 year 2 years 3 years
Non-discount categories A Dr.Web key file or serial number that is valid for at least six months for a similar Dr.Web product 0,6 1,17 1,72
Educational institutions, libraries, and health-care institutions A copy of a document, issued by a competent authority and authorizing the entity in question to carry out educational or health-care activities, and a completed application 0,35 0,7 1,05

The 40% renewal discount is only available to users of three-month Dr.Web trial licenses.

The discount does not apply to 30-day trials. To continue using Dr.Web, you must purchase a new license either from one of Doctor Web’s partners or via the Dr.Web eStore.

Renewal discounts are not available to users of beta versions but only to users of commercial Dr.Web licenses. Licenses for tested products are provided for free to the best beta testers.

  • If you have a license for one of the personal Dr.Web anti-viruses, simply buy a renewal license from one of partners of Doctor Web or the Dr.Web eStore. The price of a renewal license already includes the discount.

IMPORTANT! You can also purchase a standard, full-priced license. If you have used Dr.Web before for at least six months and specify during registration your previous serial number or key file, the new license period will be 150 days longer than specified on the box/in the license.

If you have purchased a renewal license (its price already includes the discount) but can't specify a previous serial number or key file whose period of use was/is at least six months in duration, the period of your new license will be 150 days shorter than specified on the box/in the license.

  • If you use a Dr.Web bundle, you can't apply for the renewal discount since special low prices are set for Dr.Web bundles by default.
  • If you use any other Dr.Web product, please visit the renewal page.

The 150-day bonus is given to customers who purchase Dr.Web at the standard, full price when renewing their licenses.

A renewal product may be unavailable when a customer is ready to renew. In such cases, the only choice is to buy a full-priced license. So, during registration, instead of the discount, such customers get an extra 150 days of use added to their renewal license. The renewal bonus serves as a refund of the renewal discount they would have received had it been available.

There are no renewal restrictions as to how long ago your license has expired. You can renew it at a discount in several months or even years after its expiration.

You can register a renewal license’s serial number at any time, even before your current license expires. During registration, the remaining period of the current license will be added to the renewal licence’s term automatically. All you need to do is specify your current serial number or the key file used with the Dr.Web anti-virus.

A key file is a special file containing information about the Dr.Web components covered by your license and your license period. The file has the .key extension and is located in the Dr.Web anti-virus installation directory. In Windows, the default location is C:\Program Files\DrWeb\drweb32.key.

If you renew an expired license, the renewal period will start as soon as you register the serial number of the new license.

Legal persons purchasing Dr.Web from the eStore can get hard copies of invoices for their purchases.

If your license is valid for at least six months, you, as well as any user of Dr.Web, can renew your license at a discount.

All registered Dr.Web users are entitled to a renewal discount. The discount amount depends on the period of your renewal license.

It depends on the date of registration of your serial numbers. If you register both numbers on the same day, the license periods will start and expire in three months. If you register one serial number and register the second one three months later, you will be using licensed Dr.Web software for six months. But this may not be a good idea since you won't be able to get a renewal discount for two three-month key files, and two short-term licenses will cost you more than one six-month license.

Terminating use of a license when switching PCs/Macs

Users of Dr.Web who have commercial or OEM licenses can transfer their license from one computer to another, provided that they stop using Dr.Web on the machine from which the license has been transferred, once the license to the other computer has been activated.

Free demo licenses are not transferable.

If you intend to install Dr.Web on another computer, it is recommended that you download the latest distribution version beforehand. To do so, use the option “Download full version”.

My license (serial number) is lost. How can I transfer my license?

If you don't have a license certificate, an e-mail from your retailer of the e-license or a license key file, you can contact Doctor Web support to retrieve your serial number’s license. To do this, on the support page select "I am a registered user of Dr.Web". Then click on the link "Key file or serial number is lost?". Follow the instructions.

Transferring a license after a computer has been repaired

It is recommended that you delete the license key file before handing over your computer for repair to make sure that your license does not end up in someone else's possession. To do this, right-click on the Dr.Web icon located in the system tray, and in the context menu, select Tools – License Manager. In the Manager window, you will see the name of the key file. Move the file from the local directory onto a removable drive, and then use the License Manager to remove the license. Once repairs are done, use the license manager of your installed Dr.Web anti-virus to add the key file.

I'm going to format my hard drive. How can I save my license?

Save the key file on a removable data storage device before you format the disk. To do this, right-click on the Dr.Web icon located in the system tray, and in the context menu, select Tools – License Manager. In the Manager window, you will see the name of the key file. Save it from the computer’s local directory to removable media. After formatting, download the latest version of the distribution. To do so, use the option “Download full version”.

Boxed products

To transfer a license from one computer to another, save the serial number or license key file onto removable media. To do this, right-click on the Dr.Web icon located in the system tray, and in the context menu, select Tools – License Manager. In the Manager window, you will see the name of the key file. Save it from the computer’s local directory to removable media.

If you purchased a Dr.Web product on tangible media in a box, you can find the serial number in the “Serial number” field of your license certificate. If the Dr.Web product has been removed from the computer, you can use the license key file to activate the license on another machine. The file's extension is .key. It is stored in the product's installation folder (Program Files\DRWEB). The folder is not deleted after the removal of a product. Use the License Manager of the Dr.Web product installed on another computer to add the key file or enter a serial number.

Electronic licenses (including OEM licensess)

To transfer a license from one computer to another, save the serial number or license key file onto removable media. To do this, right-click on the Dr.Web icon located in the system tray, and in the context menu, select Tools – License Manager. In the Manager window, you will see the name of the key file. Save it from the local directory computer to removable media.

If you have purchased the e-license in an online store, you can find the serial number in the e-mail you received from the store. If the Dr.Web product has been removed from the computer, you can use the license key file to activate the license on another machine. The file's extension is .key. It is stored in the product's installation folder (Program Files\DRWEB). The folder is not deleted after the removal of a product. Use the License Manager of the Dr.Web product installed on another computer to add the key file or enter a serial number.

Demo

Free demo licenses are not transferable.

If you purchased Dr.Web for Android via Google Play

To transfer your license to another Android device, use the device to log in on Google Play under the account you used to purchase the license. Then select your Dr.Web product on Google Play and click "Install". The license will be recognized automatically.

Boxed products

Customers who purchase any boxed Dr.Web product are entitled to use Dr.Web Mobile Security free of charge. If you've lost your device or bought a new one, you can transfer your license to another device. Download and install the corresponding Dr.Web program on the device. Copy the key file obtained when registering your boxed Dr.Web anti-virus into the installation directory of your Dr.Web for a mobile device.

Single-user licenses and OEM

Buyers of Dr.Web Mobile Security may transfer the license to another mobile device in the event of loss/acquisition of a new device. Download and install the corresponding Dr.Web program on the device. If you have purchased an e-license in an online store, you can find the serial number in the e-mail you received from the store. Copy the key file obtained when registering your electronic license into the installation directory of your Dr.Web for a mobile device, or enter the serial number.

Prior to the installation, we strongly recommend doing the following:

  • Install all the critical updates released by Microsoft for your operating system (updates can be downloaded from the Microsoft update site);
  • Use system tools to check the file system and fix problems, if any;
  • Close other running applications.

To run the installation in normal mode, use one of the following:

  • If the installation kit is a single executable file, launch the file.
  • If the installation kit is furnished on a branded disk, insert the disk into your optical drive. If autorun is enabled, the installation procedure will start automatically. If autorun is disabled, launch the autorun.exe file located on the disk. The autorun window will appear.

Then proceed with the following steps:

  • Press Install.

Follow the installation wizard instructions. At any installation step before file copying process is started you can use the two buttons:

  • Press Back to return to the previous step;
  • Press Next to move to the next step;
  • Press Cancel to cancel the installation.

In order to check the version number, right-click on the Dr.Web icon in the notifications area and select About. In the next window, you will see the Dr.Web version number and all the modules versions as well.

When purchasing our anti-virus, you obtain a certificate indicating which product the license you have bought is applied to. So, you need to install the product indicated.

There are two ways to do it:

  1. Disable anti-virus self-protection (right-click on the Dr.Web icon in the notifications area, select Disable self-protection, enter digits from the CAPTCHA and press Disable self-protection), then copy the drweb32.key key file from C:\Program Files\DrWeb (or the anti-virus installation folder) to a removable media. After that, locate the drweb32.key file path during the anti-virus installation the new OS.
  2. Download the latest Dr.Web version from our website and launch the installation. During the installation, enter your serial number; the key will be downloaded and installed automatically.

In this case, you need to download the latest anti-virus distribution file from our website and install it.

In default installation, all the anti-virus package components are automatically installed into C:\Program Files\DrWeb\ folder.

In custom installation, you can specify the list of components to be installed (e.g. you may choose not to install a firewall if you don’t need it), select installation folder and configure update server.

To have this error fixed, you need to download and install an update for Windows, and then restart anti-virus installation.

It is not allowed to install several anti-virus programs on one PC at a time — they will conflict with each other that may considerably slow down you PC or make it completely non-operational. If you have an anti-virus software already installed on your PC, but intend to install a new product from another vendor, then you need to remove the anti-virus program you have, prior to the installation.

If you wish to install another anti-virus program, you do it at your own risk, and become responsible for all the consequences because the consequences of such installation might be unpredictable including inability of your OS to boot as a result of two or more anti-viruses installed on your PC.

The utility is not designed to be used as a main Dr.Web software uninstallation tool. Dr.Web Remover utility is a damaged Dr.Web version emergency removal tool. The anti-virus is recommended to be uninstalled with the standard Windows tools.

If the installed version of Dr.Web Anti-virus was damaged for some reasons and cannot be removed in a regular way — please use the Dr.Web Remover emergency removal utility. Run Dr.Web Remover, enter the code from the CAPTCHA (it is necessary in order to confirm that is the user, not application, who attempts to remove antivirus) and press Remove.

Like any other program, Dr.Web Anti-virus can be removed with standard operating system tools:

  • In Windows 2000/XP: From Menu–>Control Panel–>Add/Remove programs.
  • In Windows Vista/7: From Menu–>Control Panel–>Programs and Features.

If you were unable to remove the anti-virus in such a way, please use a special Dr.Web Remover utility, which can be downloaded here.

Dr.Web Remover is intended to be used to delete the results of incorrect/damaged installations of Dr.Web for Windows. The supported versions are 4.33, 4.44, 5.0, 6.0, 7.0, and 8.0. The utility can also be used with the same versions of Dr.Web Enterprise Suite client software when standard removal tools are not available or do not work.

The Exclusions section lets you launch legitimate applications whose ability to work could be hindered by the anti-virus as well as open websites that interest you but may be on the list of non-recommended sites.

Don't ever add Windows system directories, temp folders, torrent-tracker sites, file catalogues, or sites hosting illegal software and video content.

Any option can be changed, and any restriction can be removed.

Important! The more exceptions you add in the anti-virus settings and the fewer restrictions you set for applications and websites, the lower the system security will be.

Email addresses can be forged, instant messengers can be compromised, and sites and flash drives get infected. A source may seem reliable to you just because a friend told you about it. If Dr.Web gives you the danger signal, delete the file and never open the link.

Under normal circumstances, you should never do that. Disabling Dr.Web components can be very dangerous: while SpIDer Gate is disabled, the anti-virus isn't scanning traffic.

Go to Security Center → Exclusions → Website, and add the URL to the list.

You can use patterns to add multiple objects with a single list item.

Make sure that the performance issues you are experiencing really are being caused by Dr.Web scanning that specific application, and add its executable files to SpIDer Guard's exceptions. If that doesn't help, contact Doctor Web's technical support.

Right-click on the Dr.Web icon in the system tray, and select Security Center. Go to the Statistics tab, and select Detailed report. In the newly opened window, click on the event you are interested in. Look through the list to find information about the site or program being blocked. Add the URL or file/application to the exception list being used by the component that has been blocking it.

Go on Doctor Web’s site to find out more about the threat that’s been detected, and check whether the troubleshooting section in the application's documentation contains any mention of possible issues related to the anti-virus software. Then allow the application to be launched or block its launch. If you can't decide what to do, you should contact our support service.

Access to the site will be denied, and the block page will be displayed.

In the system tray, click on the Dr.Web icon, and select Security Center. Go to the Statistics tab, and select Detailed report.

Exceptions are defined separately for each component. To access the settings, go to Security CenterExclusions. Some options can be changed in the component settings (Devices and Personal Data, Parental Control, Preventive Protection).

Go to Security CenterExclusions; specify the application as an exception for all the components, or define the application's parameters in the Preventive Protection settings.

Both are aimed at keeping the anti-virus current to protect a computer against any and all threats, including the latest ones. The difference is that when only the virus databases are updated, you don’t need to reboot the system, but when the anti-virus components are updated, rebooting may often be necessary. We strongly recommend that you act on Dr.Web reboot notifications related to component updates because out-of-sequence updating may lead to a weakening of protection.

Rebooting is needed so that the updated Dr.Web drivers work properly with the operating system. Our competitors’ anti-virus solutions are updated in the same manner.

Doctor Web strives to release Dr.Web component updates, especially critical ones, as quickly as possible. After all, the reliability of the protection directly depends on the anti-virus’s ability to intercept and cure the latest threats and still operate error free. Experience shows that for each individual product, updates that require a reboot are being released no more than once or twice a month, the only exception to this being recently released program versions and those under active development.

In the window that notifies users that a reboot is required, you can choose when you want the system rebooted. You can choose to do it now or postpone it until a time convenient for you.

Just one Dr.Web database entry can lead to the detection of tens, or hundreds, or sometimes even thousands of similar viruses.

Moreover, the presence of Origins Tracing™ and structural entropy analysis in the Dr.Web anti-virus makes it possible to detect malicious programs that are so new they have yet to undergo analysis in the Doctor Web anti-virus laboratory.

The smaller number of virus entries (compared to some other anti-virus programs) even makes it possible to detect unknown viruses (i.e., those not in the virus database) with a high degree of certainty. These are viruses that will be created on the basis of existing viruses.

How do users benefit from the small size of the virus database and the fewer number of entries in it?

  • Hard drive space is conserved
  • RAM is conserved
  • Less Internet traffic is used when updates are downloaded
  • The virus database can be downloaded at high speed, and it can operate quickly when analysing viruses
  • Future viruses, those that will be created in the future by modifying existing viruses, can be detected

Thus, the fundamental difference between the Dr.Web virus databases and the virus databases of other anti-virus programs is that with its fewer number of database entries, the Dr.Web database allows as many (or even more) viruses and malicious programs to be detected.

Virus databases do indeed get larger with each update. But Dr.Web solutions use the most cutting-edge anti-virus database format so that as the virus databases get bigger, scan speed is not reduced.

Moreover, because the latest technologies are applied to Dr.Web solutions, the size of the virus databases can be reduced. This is because they exclude entries containing information about malicious programs that are automatically detected with the help of the newest technologies.

When an Internet connection is present, the anti-virus updates every 30 minutes by default (this is the most optimal setting).

When required, you can change this setting by doing the following: right-click on the Dr.Web icon located in the bottom-right corner of the system tray. Then, in the context menu, select Tools → Settings and go to the Updating tab.

Alternatively, you can update the anti-virus manually by right-clicking on the Dr.Web icon in the bottom-right corner of the system tray, and then selecting Updating in the context menu.

No, that’s not true. When you buy the anti-virus, you are paying not only for the program itself, but also for the right to get anti-virus database and module updates as well as the opportunity to contact the technical support service while your license is valid. Nobody will ever come after you for additional money! Proof of this can be found in the Dr.Web license agreement which you are invited to read before you install the anti-virus. Doctor Web assumes a number of obligations and guarantees the following:

‘Throughout the entire software usage period, the User is granted the right to receive through the Internet virus database updates as well as upgrades of the software modules as they are made available by the Rights Holder’.

The Dr.Web license agreement is a legal document that guarantees your rights as a consumer.

Hundreds of thousands of new viruses appear DAILY — and correspondingly, tens of thousands appear every hour. The overwhelming majority of them are modifications—brothers and sisters of existing viruses. Yes, the Dr.Web heuristic analyser and the Dr.Web behavioural analyser really do make it possible to detect with a high degree of probability that a file has been infected or is a Trojan itself. But “probably infected” does not mean “infected for sure”! This file will be declared a virus only after its virus signature has been added to the Dr.Web virus database.

But no anti-virus software vendor will ever guarantee you that today won’t be the day that somebody writes a brand new virus that can’t be detected by even the most perfect heuristic analyser.

As a rule, malicious programs reach their victims at the same time they reach the Doctor Web anti-virus laboratory for analysis, and in the case of the newest malicious programs (those not yet detected by any available mechanism), anti-virus analysts need time to develop and test a “cure”. Frequent updating makes it possible to minimise the time it takes for potential victims of criminal attacks to get hold of updates. Often ‘cures’ for malicious files are available, but have not yet been downloaded.

Unlike its competitors, Doctor Web’s principled position is to release updates as frequently as possible so as to minimise the time period during which new threats can pose a danger.

That is why the anti-virus databases need to be updated every time the computer is connected to the Internet or as frequently as possible if the connection is continuous.

First do the following:

  • Make sure that your computer is connected to the Internet.
  • If you are using a firewall, go into its settings and allow the drwupsrv.exe update module, located in the folder containing the installed Dr.Web software, to access the Internet.
  • If you access the Internet through a proxy server that requires authentication with a username and password, go to the settings and specify the proxy server’s address and port, and the username and password for it. To do this, right-click on the Dr.Web icon in the notification area, and select Tools –> Settings. In the next window, go to the Proxy server tab and configure the proxy server settings.

If after trying the above, you are still experiencing difficulties, please contact the Doctor Web technical support service and describe in detail how your computer connects to the Internet (note: if a proxy server is involved, please specify whether authentication is required, and whether your browser or Dr.Web update module is configured to be used via the proxy server).

Anti-virus update downloads can include updated anti-virus databases as well as application files. In the latter case, a system restart may be required to apply the update. And in this case, the corresponding notification will appear.

The user can restart the system immediately—by closing all the running applications and pressing the Restart now button. They can also make the anti-virus show the notification later or schedule a system restart. To use either of the two latter options, first select Remind me later.

You can set the reboot time to occur within the next 24 hours.

Users are also able to restart the system on their own whenever they want. For example, go to Start → Shut down or sign out→ Restart/Shut down.

Important! Selecting the option to enter sleep mode or switching user accounts won't restart the system so that the pending updates are applied.

Important! Pressing the power button on a tablet or laptop will make the device enter sleep mode. To apply updates, restart the system using any of the available methods (including the restart option in the anti-virus notification pop-up).

There are several ways to start the scanner.

  • The scanner shortcut (the icon with a spider on the green field) is placed on the desktop during Dr.Web installation. Double-click on the shortcut and the scanner will start.
  • The green spider icon is displayed in the system tray. Right-click on the icon. In the context menu, select Scanner; the scanner will start.
  • Run the scanner via Windows Explorer to scan a specific object (file or folder). Right-click on the file or folder you want to scan. In the context menu, select Scan with Dr.Web (the item with the red spider icon). The Scanner will start immediately and the file will be scanned.
  • Check the specific object (file or folder) you’ve found by dragging it onto the scanner icon or its open window when custom scan is selected.

In respect to infected and incurable objects, the Move action does the following: The file is moved to a special quarantine folder. Furthermore, once moved, the file loses its extension. The virus is literally disarmed and rendered non-operational and, therefore, harmless. Later, you can open the Quarantine Manager and delete the files if you do not need them.

If you have not installed the self-protection module, do the following:

  1. Download the latest version of the curing utility Dr.Web CureIt and run a full scan. Cure detected infected objects and delete or move to the qurantine incurable malicious objects.
  2. After that you need to reinstall the anti-virus. Open Add and Remove Programs (Windows 2000 \ XP) or Programs and Features (Windows Vista / 7) in the Control Panel, and remove Dr.Web anti-virus. After rebooting, go to C: \ Program Files \ DrWeb (or another folder into which Dr.Web has been installed) and remove all files and folders, but the license key file drweb32.key.
  3. After that, download the latest distribution of the antivirus program and install it. To register, use the saved key file.

Quarantined files can be deleted by selecting the desired file and clicking Delete. It will remove the file from the quarantine and from the system.

A Dr.Web anti-virus is a set of programs, each of them protects its own section in your computer's defense. Removing or disabling at least one component greatly reduces the reliability of anti-virus protection in general, so we strongly advise you not to disable any of its modules unless absolutely necessary.

To temporarily disable self-protection, right-click on the Dr.Web icon in the system tray and in the context menu select Disable self-protection (if this feature is unavailable, please switch to the Administrative Mode and try again). A window will appear where you'll need to enter numbers from the picture and click Disable self-protection.

Caution! Disabling self-protection is not recommended, activate it again as soon as possible.

Right-click on the Dr.Web icon in the system tray and select Tools–> Quarantine. In the subsequent window select the file and click Restore.

Quarantined viruses are not dangerous because they can't be launched. If you want to permanently delete infected files, clean the quarantine:

  • If you are using Dr.Web for Winidows 5.0 and Dr.Web Security Space 5.0: remove all objects from the infected!!! folder, located in the anti-virus's installation folder.
  • If you are using Dr.Web for Winidows 6.0 and Dr.Web Security Space: right-click on the Dr.Web icon in the system tray and select Tools–> Quarantine. In the subsequent window select the files you want to remove and click Delete.
  • If your anti-virus is Dr.Web CureIt!, remove all objects from the C: \ Documents and Settings \ _your_user_name_ \ DoctorWeb \ Quarantine folder.

Dr.Web SelfPROtect protects the modules, processes, and branches of the registry used by Dr.Web for Windows from outside interference. The outside interference includes incompetent user actions that may render the anti-virus non-operational or make it malfunction as well as actions taken by anti-antiviruses that may terminate anti-virus processes, modify and remove its files and delete Windows Registry branches related to Dr.Web. Disabling the self-defense is not recommended!

The quarantine is a special folder where the anti-virus stores suspicious and infected files. Suspicious files are stored to be later sent to Doctor Web's laboratory for analysis, infected files get into the folder if their removal and curing is impossible for some reason.

  • If you use Dr.Web for Windows 5.0 and Dr.Web Security Space 5.0 the quarantine folder name is infected!!!, It is located in the anti-virus installation folder (default path C: \ Program files \ Drweb).
  • With Dr.Web for Windows 6.0 and Dr.Web Security Space access to the quarantine is only available through the program interface. To access the quarantine, right click on the Dr.Web icon in the system tray and select Tools–> Quarantine.
  • Dr.Web CureIt! placed quarantined objects into C:\Documents and Settings\_Your_user_name_\DoctorWeb\Quarantine.

Infected files are moved to a special storage — Quarantine — from where you can remove the file if necessary, restore it to its original location or send it for analysis in our virus lab.

  • If you use Dr.Web for Windows 5.0 and Dr.Web Security Space 5.0, the quarantine folder name is infected!!!, It is located in the anti-virus installation folder (default path C: \ Program files \ Drweb).
  • With Dr.Web for Windows 6.0 and Dr.Web Security Space access to the quarantine is only available through the program interface. To access the quarantine, right click on the Dr.Web icon in the system tray and select Tools–> Quarantine.
  • Dr.Web CureIt! places quarantined objects into C:\Documents and Settings\_Your_user_name_\DoctorWeb\Quarantine.

To answer this question, you need to understand the difference between viruses and Trojan horses. Typically, a virus adds (appends its code) itself to an infected file so it incorporates its own code and the virus's code. Together they represent a virus-infected file. Most of these files can be cured by the Dr.Web anti-virus. Here we speak about curing files of viruses rather then curing viruses.

A Trojan horse is a complete malicious program. It doesn't inject its code into files but operates as a separate program, that's why it can't be cured but removed. Some Trojan programs compromise various system objects such as the Windows Registry. In this case we can speak about curing the system (but not the Trojan horse), which includes removing the Trojan and restoring the compromised objects to their healthy state.

To enter the safe mode when your PC is booting, press F8 at the moment the computer vendor picture disappears, before Windows logo is displayed.

It is not allowed to install several anti-virus programs on one PC at a time — they will conflict with each other that may considerably slow down you PC or make it completely non-operational. If you have an anti-virus software already installed on your PC, but intend to install a new product from another vendor, then you need to remove the anti-virus program you have, prior to the installation.

If you wish to install another anti-virus program, you do it at your own risk, and become responsible for all the consequences because the consequences of such installation might be unpredictable including inability of your OS to boot as a result of two or more anti-viruses installed on your PC.

These instructions are intended for users of Dr.Web Security Suite and current versions of Dr.Web Anti-virus for Windows.

Dr.Web technologies are designed to prevent user data, including passwords, from being obtained by hackers. The password is not stored in plain text, so it cannot be recovered.

In addition, Doctor Web does not collect the personal data of Dr.Web users, and, therefore, passwords cannot be recovered by contacting our technical support service.

You have to reinstall the product you are using so that you can gain access to the anti-virus’s settings. Once you do this, all the settings you previously configured, including your password, will be lost.

  1. Save the Dr.Web key file (this file has the .key extension and contains information about your license). The file can be found in the directory C:\Program Files\DrWeb. For example, put it on your desktop.
  2. To reinstall Dr.Web, you will need its distribution. Download it in the Download Wizard. Enter your serial number or your key file—the file with the extension .key that contains information about your license (you can find it in the directory C:\Program Files\DrWeb)—and your registered email address, and then click on the Download button. In the newly appeared window, the download option for Windows and Android is already selected, so you can just click on the Send button. In the next dialogue box, select the download version:
    • 11.5 if you are already using Windows XP;
    • 12 if you are using Windows Vista and later versions.

    Dr.Web does not support versions below Windows XP.

    Download the Dr.Web distribution.

  3. Remove the anti-virus.

    Go to the Control Panel, and select StartSearchControl Panel. After this, depending on the type of Control Panel you have — Programs and Features or Remove program.

    In the list of programs, select Dr.Web Anti-virus or Dr.Web Security Space. Click on Remove, and follow the Removal Wizard's instructions.

    In the Parameters to save window, clear the checkbox next to Settings.

  4. After you remove the solution, restart the computer, and reinstall Dr.Web. Your key file will be downloaded automatically.

    If the key file is not downloaded automatically during the installation, enter it manually. To do this, in the anti-virus's menu, select Licenses. In the License Manager window, click on the Buy or activate new license button. Then click on the text or specify the key file, and select the previously saved key file — the desktop file that begins with SL and has the .key extension.

If the problem persists, please contact the technical support service.

No, SpIDer Gate is an HTTP-monitor. It performs the following tasks:

  • Scan incoming and outgoing HTTP-traffic
  • Intercept all HTTP-connections
  • Filter Data
  • Block loading infected pages automatically in any browser
  • Scan archived files
  • Protect from phishing and other dangerous online resources.

At the same time the firewall protects your PC or network from unauthorized access.

Thus, SpIDer Gate and the firewall must operate simultaneously on your computer to protect your system against viruses and network attacks.

No. SpIDer Gate operates independently of the programs that use the Internet (including browsers).

Dr.Web anti-virus engine is so fast that SpIDer Gate won’t delay loading of web-pages or slow-down file transfers.

Further, if required, you can reproduce the problem that must be analysed using the extended report. Please keep in mind that the Debug log is not always required because redundant information might complicate troubleshooting.

It is not recommended to disable the SpIDer Gate HTTP monitor because nowadays a lot of malware is distributed via infected websites. There are many script viruses and exploits that can cause harm to the system before they are saved to your hard drive and, consequently, detected by the SpIDer Guard® file monitor.

If disabling HTTP monitor is still necessary, right-click on the Dr.Web icon and in the next menu, select SpIDer Gate –> Disable. When anti-virus self-protection screen appears, type digits from the picture into the string and click Disable SpIDer Gate.

Right-click on the Dr.Web icon in the system tray and select SpIDer Gate-> Disable in the context menu.

Caution! It is not recommended to disable the HTTP-monitor SpIDer Gate because nowadays a lot of malware is distributed via infected web sites. There are many script viruses and exploits that can harm the system before they are saved to your hard drive and, consequently, detected by the file monitor SpIDer Guard.

Since SpIDer Gate utilizes the Dr.Web engine and databases, it is updated automatically along with other anti-virus modules.

As other modules of the program Dr.Web, SpIDer Gate features the same anti-virus engine and uses the same virus databases and therefore is updated along with other modules.

The red icon indicates that SpIDer Gate is disabled. To activate it, right click on the Dr.Web icon in the notification area. In the menu, hover over the SpIDer Gate item and in the drop-down list select Enable.

If the icon remains red, you have two options:

  • Application error – in this case you need to contact the Technical support service.
  • Your license does not cover SpIDer Gate. In this case, it is recommended to remove the component: Go to Start-> Settings-> Control Panel-> Add and Remove Programs, find the Dr.Web anti-virus on the list, click Modify and follow the wizard's instructions to disable this component.

The unique Dr.Web anti-virus engine allows SpIDer Gate to scan traffic so quickly that you will never notice any delay when viewing web pages and downloading files from the Internet.

If you believe that SpIDer Gate has mistakenly blocked a respected site, please let us know through the form on our website.

If you need to access a suspicious site, right click on the Dr.Web icon in the system tray and in the context menu select SpIDer Gate-> Settings. Clear the Block known source check box and press Ok.

Caution! Disabling this option is not recommended, because pages from all sites, including potentially dangerous ones will be loaded without a corresponding warning.

SpIDer Gate's log file name is spidergate.log. The file is located in the C:\Documents and Settings\Your_user_name\DoctorWeb folder.

SpIDer Gate is compatible with all web-browsers.

Dr.Web anti-virus engine is so fast that SpIDer Gate won’t delay loading of web-pages or slow-down file transfers.

The Speed balance option allows you to adjust the amount of CPU time utilized to scan Internet traffic. The higher the scanning priority, the more CPU resources it will use, but it will help maintain high speed connectivity. Low priority results in low CPU load and slower network communication speed. Changing the default value usually is not required.

One of SpIDer Gate’s tasks is to inform users that visiting some websites is dangerous or undesirable, for reasons that include the presence of “pirated” content. Dr.Web informs users about such websites because they are accompanied by malicious programs. Websites are included in the so-called Dr.Web “anti-piracy” database only on the basis of allegations made by content copyright holders. Each allegation is verified by Doctor Web’s lawyers before the decision is made to include the corresponding URL in the database. When users receive SpIDer Gate notifications concerning the undesirability of visiting pirated websites, they are getting objective, legally considered information about intellectual property infringement. Thus, Doctor Web helps users of its products:

  • avoid becoming the victims of criminals, who for their own selfish ends use others’ works and trademarks, and the fruits of others’ intellectual labours, for illegal purposes;
  • avoid potential criminal indictment for downloading, using, and further distributing pirated content;
  • protect PCs against infections occurring as a result of downloading unlicensed content that is accompanied by malicious programs.

Users make their own decisions as to whether it is worth visiting the websites they have been notified about. The SpIDer Gate component can be enabled or disabled at their discretion.

Right-click on the Dr.Web icon in the notification area and select Parental Control → Settings. Enter the password and select Allow access to all sites. In the Local Access tab, select Allow and Unlimited in the corresponding sections. Click Apply to save the changes.

Caution! Disabling Parental control will allow access to all resources on the Internet, LAN and the PC.

There is no way to recover a Parental control access password. The only solution is to import a new password into the registry from a special file.

  1. Use the download link to obtain the file
  2. Disable the anti-virus's self-protection
  3. Double-click on the downloaded file and agree to modify the registry
  4. Enable self-protection
  5. Now your password is "drweb" (without the quotes), do not forget to change it in the Parental control settings.

Right-click on the Dr.Web icon in the notification area and select Parental Control → Settings. If this is the first launch of the Parental control module, you will need to set a password for it. Then in the subsequent window select what you want to block and then click Apply.

If the password for parental control is not specified, each time you open parental control settings, you will be prompted to set a password. It is Recommended that you set a password right away to prevent unauthorized access to these settings. If no password is required, click Cancel.

If upon activating the Parental control you receive the message "Unable to find a key file", it means that your license does not cover the Parental control. In this case, it is recommended to remove the component: Go to Start–> Settings–> Control Panel–> Add and Remove Programs, find the Dr.Web anti-virus on the list, click Modify and follow the wizard's instructions to disable this component.

Use the local access settings to restrict access to resources on your computer - files and folders. In addition, it is possible to prohibit the use of removable storage media and access to the LAN. By restricting access to such resources you can avoid damaging or removing sensitive data by a third party and prevent unauthorized access to confidential information.

The Parental control module allows you to restrict users' access to certain sites on the Internet, local files and folders, local network resources. An administrator can manually configure a list of banned sites or take advantage of the constantly updated thematic lists provided by Doctor Web.

Local access protection and the URL filter are parental control features disabled by default. You need to activate them manually by setting the parental control operation mode and access password in its settings.

The Parental control module can restrict acces to any specific sites or web-pages, as well as to all known sites containing information on certain subjects (such as sites about drugs or weapons, sites of paid on-line games, etc.). A list of specific websites to be blocked is set up by the user; both individual addresses and keywords found in URLs can be specified in this block list. Blocking websites by subject is carried out automatically using the lists, updated regularly by Doctor Web.

If you set a password for accessing the Parental Control, only the computer's administrator will be able to do so after entering the password. If no password is set, then any user with administrative privileges will be able to change the settings.

Dr.Web scanner for Windows either scans files at the user’s command or on the schedule specified in the Scheduler. Not all the files are checked, but only those specified in the scanner settings instead. By default, files are checked by format — i.e., files in archives, packed and e-mail files, and RAM and all the autorun objects as well. You may choose to scan disks, folders, scan by file types, by preset mask, or scan all the files. To view current scanner settings, go to the program main window menu bar and select Settings–>Modify settings.

Quick scan of the critical system objects with the anti-virus scanner is launched automatically as the program starts. It is required to find out if any viruses exist in the system. After the scan is complete, two right windows indicate numbers. The left one shows the number of viruses found on your PC, while the right one — the number of RAM objects and files scanned with the anti-virus scanner.

In order to launch full scan, please use the Task scheduler.

Windows XP:

Open the Windows task scheduler (Start->Control panel->Assigned tasks). Find the Dr.Web Daily Scan task pre-installed during installation and open it to edit. In the Task tab, check Enabled. In the Schedule tab, specify scan frequency and time you need. Press Ok to apply the settings. Enter user name and password upon the operating system request.

Windows Vista/7:

In order to edit a task pre-installed during the anti-virus installation, right-click on the Dr.Web icon in the notifications area and select Tools->Scheduler. In the next window, select the Drweb Daily Scan task, which is disabled by default. You should enable it (by right-clicking the task and selecting Enable option). In the Triggers tab, edit launch time and frequency.

The Move action in respect to infected and incurable objects means the following: an object is moved to a special directory specified in the Move to field (by default, it is the infected.!!! subdirectory of the Dr.Web installation directory) and accessible even after the scan is over. Furthermore, after having been moved, the file loses its extension. Such actions mean that the virus is actually “disarmed”, rendered incapable and, therefore, absolutely safe.

To have all the messages marked with Dr.Web spam filter automatically moved to a specific folder — let's call it Spam, for example, — follow the below steps:

  1. Right-click on the Dr.Web icon in the notifications area and select SpIDer Mail–>Settings. Go to the Anti-spam tab, and check the box next to Add a prefix to the Subject field of e-mails containing spam. In the field below, enter any word or letter combination you like — that's what will be a prefix Dr.Web spam filter will add to the subjects of messages specified to be a spam.
  2. In your e-mail client, create a folder for spam filtering and configure rule for it so that messages having a prefix you have entered to the Add a prefix to the Subject field of e-mails containing spam be placed into it automatically.

Below are detailed steps on how to set up rules for various e-mail clients. It is assumed that the Anti-spam is configured to mark an incoming spam with the [SPAM] prefix. If you chose an alternative prefix, use it in accordance with this manual...

  • To make it short, let’s apply “spam” name to all unsolicited e-mails. The bulk of it comprises advertisements offering different goods and services.
  • The most dangerous among spam messages are phishing, pharming and scamming ones. Nigerian scams, lottery and casino scams, fraudulent messages from banks and credit organizations are characteristic of them.
  • Next come black political and economic PR scams and the so-called “letters of happiness”.
  • There is also a technical spam, or bounce messages, generated by mail servers in reply to undelivered message, whether you did send one or not. Such e-mails might emerge as a result of mail server poor work or virus activity, of some e-mail worm, for instance.

Incoming mail filtering is processed by SpIDer Mail, one of Dr.Web modules. The following steps describe how to activate the spam filter:

  • In SpIDer Mail menu on the Windows Task Panel choose “Settings” – the SpIDer Mail “Settings” window will appear.
  • In the “Scan” pane of the SpIDer Mail “Settings” window enable the “Check for the spam” checkbox and press OK to save the changes made; then close SpIDer Mail “Settings” window.

After you’ve activated your spam filter, SpIDer Mail with Vade Retro anti-spam engine integrated into it starts filtering all your incoming mail on POP3 and IMAP4 protocols.

To move automatically all messages marked as spam by Dr.Web Anti-spam into definite mail folder in your mail client, do the following.

  1. In SpIDer Mail menu on the Windows Task Panel choose “Settings” – the SpIDer Mail “Settings” window will appear. Press the “Advanced…” button. The “SpIDer Mail® Spam Settings” window will open. Check the “Add prefix to the subjects of the spam messages” box. Input any word or combination of symbols in the field below it. This will be the prefix Dr.Web Anti-spam will add to subjects of messages marked as spam.
  2. In the mail client you use, make a new folder for spam. Make the rule for this folder so that all the spam messages with the prefix you specified in the “Add prefix to the subjects of the spam messages” filed are placed there automatically.

Whitelists and Blacklists contain mail addresses you either trust or not.

  • If the sender’s e-mail address is added to the Whitelist, these messages are not filtered. However, if the sender and the receiver share the same domain name e-mail addresses and this domain name is enlisted in the Whitelist with the “*” symbol, it is filtered for spam.
  • All messages enlisted in Blacklist are marked as spam without additional analysis.

Both lists settings should be fill in one after another, parted by “;”. The “*” sign can be used as a part of e-mail address. For example, *@domain.org passes for all addresses with “domain.org” domain name.

In case some messages are falsely filtered, they should be forwarded as attachments to special addresses for analysis and correction of spam-filtering techniques.

  • Messages, falsely marked as spam , should be forwarded as attachments to vrnonspam@drweb.com
  • Messages, falsely marked as non-spam , should be forwarded as attachments to vrspam@drweb.com.

At first all spam messages were of Latin origin and spam-filters’ developers, represented for the most part by Western companies, were aimed at filtering these ones only. Later on spammers switched into Cyrillic, too. But since the bulk of spam is still in Latin, there are some difficulties to filter Cyrillic spam.

To save your Cyrillic correspondence from being filtered as spam without a prior analysis, check the “Allow Cyrillic texts” box. Otherwise such e-mails are likely to be marked as spam. “Allow Chinese, Japanese, Korean text” option works the same way.

When the firewall displays a message, it is notifying you that some program is trying to connect to the network (or, vice versa, is trying to connect to your system from the network). And it prompts you to decide what to do — to allow access or to block access.

In this case, you need to look at what program has been specified in this message, and if you recognise it, click on "Create rule" — “Allow all”.

To solve the network access problem:

  1. Right-click on the Dr.Web icon in the system tray.
  2. Click on the padlock icon and then on the gear icon (“Settings”).
  3. Select “Protection components” and then “Firewall”.
  4. In the tab, find the “Applications” header and the option “Application rules” below it. Click on “Change”.
  5. You will see a list of applications for which rules already exist. Find the ones with a red circle in front of them — your browser will most likely (but not definitely) be included in this list. Click twice on the red icon, and select “Allow all”.

To reset all the anti-virus settings (including the firewall’s):

  1. Right-click on the Dr.Web icon in the system tray.
  2. Click on the padlock icon and then on the gear icon (“Settings”).
  3. In the open tab, click the “Change” button; then click on “Reset settings”, and tap “OK” to confirm your choice.
  4. After the reset, the interface language will change to English, so you need to change it back to Russian. Click on “Main”, “Advanced”, and in the “Language” section, click on “English”. Select Russian from the list, and close the window.

You can also delete the Firewall. To do this, open the Control Panel, and then — “Add and Remove Programs”.

Folder names may vary for different versions of Windows and different viewing modes.

Find “Dr.Web Security Space” in the list, and click on “Change” → “Change components”. Then clear the checkbox next to the Firewall, and click on “Apply”. The component will be removed.

If the steps indicated above have not solved the problem, please contact our technical support service.

Right-click on the Dr.Web icon in the notification area. In the menu, hover over the Firewall item and in the drop-down list, select Settings. Click the Application tab.

To create an application rule, click Create. In the opened window, specify the path to the executable file for the program for which you are creating the rule, and select

  1. the rule type for launching network applications:
    • Allow — to allow the application to launch processes.
    • Block — to block the application from launching processes.
    • Not configured — to customize the selected firewall operating mode for this application.
  2. and the rule type for accessing network resources:
    • Allow all — the application will be permitted to access the network.
    • Block all — the application will be blocked from accessing the network.
    • Custom — access will be determined by the parameters specified.
    • Not configured — to customize the selected firewall operating mode for this application.

You do not need to configure rules manually if the firewall is operating in the training mode — it is easier to configure access for each application right from the firewall notification window when it attempts to connect to the network for the first time.

Dr.Web Firewall has four operating modes:

  • Allow unknown connections — all unknown connections are allowed. Protection is not active.
  • Training mode (create rules for known applications automatically) — learning mode. Rules for known applications are created automatically. The user will be prompted to choose what action to take with all unknown connections.
  • Interactive mode — learning mode. When the operating system or an application attempts to connect to a network, the firewall will prompt the user to choose an action.
  • Block unknown connections — all unknown connections will be blocked without prompting the user.

If you install a Dr.Web package that includes the firewall, you will be prompted to deactivate the Windows firewall. The Windows firewall must be disabled, doing otherwise will result in numerous conflicts that can cause errors or an OS crash.

Neither it is recommended to enable the Windows firewall while the Dr.Web firewall is working.

You can't disable automatic startup for the firewall with standard tools available in the system.. However, you can disable temporarily various anti-virus modules including the firewall at any moment. Right click on the Dr.Web icon in the system tray and select Firewall-> Disable in the context menu.

Note: If the Disable item is not available in the menu, switch to the Administrative mode.

Dr.Web Firewall in the real time mode creates rules for applications running in the system but are not on its list. Therefore, you must create rules for such applications when they attempt to connect to the network for the first time. A connection request is issued for specific ports and protocols utilized by the application. You can allow all the requested connections, a connection only for a specific protocol and port, or block the connection. Once the rule is created, the firewall handles requests according to the rule and no longer gives out messages regarding application's network activity to the user.

The predefined database contains rules for the most popular programs, as well as all Windows system services and applications. The database is updated on a regular basis.

For more information see the video tutorial on configuring the Dr.Web firewall.

Yes, you can. In order to disable SpIDer Guard, right-click on the Dr.Web icon in the notifications area and select SpIDer Guard–>Disable.

Enabling this option allows to block automatic launch of autorun.exe-like files from removable media and hard disk drives. This option is used to neutralize autorun-viruses, which are automatically activated when a device is connected to the PC with autorun option enabled.

Enabling this option allows to block attempts to modify HOSTS system file used by operating system to make an Internet access easier. Modifications of this file may be resulted in virus or any other malicious program activities, and this may cause loss of access to some websites or network resources as a whole.

Anti-virus guard is loaded into RAM and checks files being created or modified on the hard disk and all the files being opened on network disks and removable media “on the fly”.

Besides, SpIDer Guard constantly traces running processes activities specific to viruses and blocks those processes upon their detection.

Upon detection of infected objects, SpIDer Guard interacts with them according to the specified settings.

SpIDer Guard log file is called spiderg3.log and located in the anti-virus installation folder (by default, it is C:\Program Files\DrWeb).

Paranoid mode is an enhanced protection mode. When this mode is activated, the guard starts scanning all the files being opened, created or modified on hard disks, removable media and network disks.

In the Optimal mode the guard scans only files being launched, created and modified on hard disks, removable media and network disks.

In order to exclude a program or file from the SpIDer Guard scan, right-click on the Dr.Web icon in the notifications area and select SpIDer Guard–>Settings. In the next window, proceed to the Exclusions tab, press the Browse button to select the folder where the program to be excluded from the scan is installed, and press Add.

Should it become necessary to exclude a folder or file while the Dr.Web for Windows Scanner is running — select Settings–>Modify settings in the scanner menu. You may add a folder in the Scan–>Excluded paths list tab, and a certain file in the Excluded files list, then you need to press Add.

If the spam filter misrecognizes some letters, they can be forwarded to special mail addresses for analysis and improving filter performance quality:

  • Send letters misrecognized as a spam to vrnonspam@drweb.com.
  • Send letters not recognized by mistake as a spam to vrspam@drweb.com.

Important! You should forward messages as attachment, not as inline.

You can test proper operability of anti-virus programs detecting viruses by their signatures with the use of EICAR (European Institute for Computer Anti-Virus Research) file.

This program is specially designed to allow you to see how the installed anti-virus will alert you to the viruses it detected, with no need to expose your PC to danger. Eicar program is not malicious but is specially tuned so that most anti-viruses treat it as a virus. Dr.Web refers to this “virus” as EICAR Test File (Not a Virus!).

To test mail anti-virus performance, you can ask a friend of yours to send you this file, or otherwise try to send it to yourself. If SpIDer Mail detects a virus — that is OK.

Malignant applications for mobile OSs are the fastest growing malware segment. As popularity of an OS is growing among users, so does the interest in it on the part of intruders, whose main goal is to get money. The number of threats to Android increases most rapidly.

Yes, there are and their number is growing. Android.SmsSend Trojan horses that emerged as early as in 2010 are the most common threats to the OS. They are designed to send SMS messages at premium numbers and sign up subscribers to various services.

Mobile banking Trojans are designed to intercept SMS messages, steal mTAN-codes and pass them to criminals who perform various financial transactions with accounts of unsuspecting victims (for example, make online purchases) pose an extreme danger. Android.SpyEye.1 is a banking Trojan for Android OS.

Such malware as Android.MailSteal.1.origin, Android.Maxbet.1.origin, Android.Loozfon.origin and Android.EmailSpy.origin. steal e-mail addresses from devices' address books and send them to a remote server, so that attackers can carry out spam mailings.

While out of the office, employees are not protected from hackers, applications they use may have vulnerabilities, their computers and mobile devices can be infected with viruses and Trojans that steal banking and payment system access passwords and money from bank accounts.

Employees regularly connect to the company's network via their device, and thus put confidential data and money at risk—not only their personal assets but corporate too. Incidents when malware gets onto a local network from personal devices, including handhelds, account for up to 70% of intrusions.

In addition, banks often send SMS confirmations to maintain security of transactions. There are malignant programs that can modify such confirmation messages. An anti-virus guarantees that incidents when money is stolen from accounts will never be concealed.

You don't need to install anything — just visit a compromised web-site. And it won't necessarily be a site with objectionable content — from intruders' point of view, hacking news portals is much more useful. News sites are the most visited ones on the Internet. They usually do not cause any suspicion among users or system administrators from companies which do not block access to such sites. That's why news portals are a very attractive field of operation to intruders. By Spreading malware through such sites, they can cause damage to a huge number of users and companies.

Dr.Web for Android protects from viruses and other malicious programs that may steal or damage information stored on the mobile device. It prevents viruses from getting and running on a mobile device.

Note: Dr.Web for Android can only protect mobile devices and its virus databases are different from those used by the anti-virus maintaining security of desktops and laptops. To protect a computer, use corresponding products from Doctor Web.

Dr.Web anti-virus occupies about 1 MB in the device memory. Only the file monitor that keeps track of the system processes resides in the memory at all times. The monitor requires a certain amount of resources, but it has no noticeable effect on overall performance.

The most dangerous threats for mobile devices are those that penetrate the firmware and system areas. The main signs that malicious behaviour is occurring in the system area are as follows:

  1. The multiple appearance of the same threats in the same areas, even after the anti-virus has removed them. Threats usually reappear after a device reset.
  2. Notifications in Dr.Web Security Auditor.

! In such situations, due to the specific features of the Android OS, it's impossible to employ the standard features of ANY anti-virus to neutralise Trojans because, just like any other application, an anti-virus installed on a non-root device does not have administrative privileges: Dr.Web can detect malicious programs that get into the Android system directory, but it is not authorised to remove them.

To close firmware vulnerabilities and neutralise threats in /system, you can do the following:

  1. Disable (if possible) these applications. This will not eliminate a threat completely, but it will neutralise it until you can remove it permanently.
  2. If your device is rooted (with superuser privileges that allow you to make any type of change you want, including to the firmware), you can try to remove malicious applications with the help of special third-party utilities.

    ! In some cases, configuring root access may lead to the device manufacturer denying to provide you with warrantied maintenance.

    Make a backup of all user data; do a reset to the factory settings; and install new manufacturer-provided firmware that has had the Trojan removed from it. You may need to wait for an update, depending on how much support the manufacturer provides.

    ! If you are not provided with the firmware, your best course of action is to return the device you purchased to the seller. You should NEVER USE this device.

We also recommend that you read the Anti-virus Times issue dedicated to this topic — "A fish rots from the head down..." Please refer to the issue "Firmly rooted" to know how Trojans can find their way into firmware.

Start Dr.Web for Android. In the subsequent window go to the SpIDer Guard section and check if the Monitor is enabled and protects the system message is displayed. If it is, the anti-virus protects your device. If the message is Monitor disabled, the monitor is not running. Tap the monitor indicator button.

To scan your mobile device for viruses, launch Dr.Web for Android, and tap Scanner. In the next window, specify the scan mode.

  • Quick scan. The anti-virus scans only files of installed applications. The fewer there are applications, the sooner the express scan will be completed.
  • Full scan. All files on your mobile device are scanned.
  • Custom scan. Scan only certain files or folders for viruses. To run a custom scan, select objects you want to scan and tap the Scan button.

Abort scan at any time by tapping Abort.

Launch Dr.Web for Android and select Statistics. The statistics window displays the number of processed files and information about all actions performed by the anti-virus components. It is possible to reset the statistics (Menu→Clear statistics), or save the log to a file (Menu→Save log).

Tap on the Dr.Web icon on the notification panel. In the succeeding window you will see all the available information about the threat. Tap on this message, then select the desired action: delete the file, place it into the quarantine, or ignore the warning.

Warning! It is not recommended to choose the Ignore option! If you believe that the anti-virus has made a mistake, select Quarantine and after that send the file to Doctor Web for a detailed analysis.

SpIDer Guard is designed to constantly protect mobile devices against viruses and other threats. It loads into the memory upon Android start-up and scans all files accessed by a user or the system in real time.

There are three ways to install the anti-virus:

Information about the number of virus definitions in the databases and date of the last update is contained in the anti-virus statistics.

  1. On the main application screen, tap “Menu” (the three dots in the upper-right corner of the screen), and select Settings and then the section Virus database update;
  2. Select the Update over Wi-Fi checkbox, and by default, mobile networks will not be used to download updates. If no Wi-Fi networks are available, you will be prompted to use the mobile Internet.

Start Dr.Web for Android and tap the Menu button on your mobile device. In the pop-up window select Settings.

Dr.Web for Android interface language corresponds to the current language of the operating system. Select English as the Android interface language and the anti-virus will switch to English automatically.

Note: to change the OS language tap Menu and point to Settings in the subsequent pop-up window. Go to Language & Keyboard, Select Language and choose the language you need in the succeeding window.

Dr.Web Security Space for Android version 12 has a new feature that lets you password-protect your Dr.Web account and the configuration of certain components. Setting a password for your Dr.Web account ensures that outsiders can’t tamper with important anti-virus and system settings.

If you’re a Dr.Web user, when you upgrade to version 12, an account will automatically be created for you provided you enabled the Anti-theft component before the upgrade.

If you’ve downloaded Dr.Web version 12 for the first time, create an account so that you can set a password for accessing Dr.Web’s settings.

In the top-right corner of the main application window, click on the menu icon.

Select Account.

Specify a valid email address. Click on Continue.

Specify an account password. It must consist of at least 4 characters.

Cybercriminals almost instantly hack passwords containing fewer than 8 characters.

Re-enter the password, and click on Continue.

You will see confirmation that you have created an account. Click on Continue.

This same password will work both to protect the settings of certain Dr.Web components and to permit access to other applications installed on the device if the Parental Control blocks access to them.

Ask your friend from the Buddies list you created when you configured Dr.Web Anti-theft to send your mobile phone an SMS message containing the text #RESETPASSWORD#.

When you receive the SMS with the command, the password reset will occur automatically. If your mobile phone is not blocked, you will see the Change password screen, where you can set a new password.

If your device was blocked, it will be unblocked.

Click on Forgot your password? on any screen that prompts you to enter your password. Read the instructions.

Open the Dr.Web account page https://acs.drweb.com and enter the key and email address you specified in the Forgot your password? window.

If the code is entered correctly, you will see this window.

Check your incoming messages—you will receive an email containing a confirmation code.

Enter this code in the Forgot your password? window, and click on Next.

Create a new password and remember it.

If you did not receive the email, click on the line Did not receive the email?, and you will automatically be redirected to the Doctor Web technical support page.

Since the new version 12 has a single password for the account and the Anti-theft settings, we will have to be sure that the person contacting us is indeed the owner of the device and the Dr.Web license.

In the support request:

  1. Specify the device IMEI (your device’s unique identifier; typically, this is a 15-digit number written in decimal digits).
  2. Attach to your request:
    • the corresponding receipt and a photo of the completed warranty certificate (if you have the device's box/packaging and the IMEI is readable, attach a photo of the box to your request);
    • proof of purchase of your Dr.Web license (an email from the eStore, a scanned copy of the payment document, or other). If you won your license during a Dr.Web auction—specify your Doctor Web account login. If you are using a trial version, please ignore this subitem.

If you no longer have access to the email you used to register your account, you will need to remove your old account and create a new one.

If you no longer have access to the email you used to register your account, you will need to remove your old account and create a new one.

Select Account.

Click on Delete account.

Delete account Delete account.

When an account is deleted, the Anti-theft and Parental Control settings will reset—you will need to reconfigure them.

Dr.Web for Android Parental Control will protect applications from unauthorised access and anti-virus settings from tampering by outsiders or children. But first Dr.Web Parental Control must be enabled.

Select Parental Control in the Dr.Web menu.

Click on the Enable button or on the switch in the upper-right corner of the window.

Grant Parental Control access to Android’s special features by clicking on Grant access.

In the Special features settings window, click on the Dr.Web Security Space button.

Use the switch to enable Android’s special features.

Close the configuration window for special features.

Go to the Applications tab, and select Settings — this will block unauthorised access to the system’s settings.

In the Components tab, select all the items—after this, a password will have to be entered to access the selected Dr.Web protection components.

Dr.Web Security Space for Android can protect against both the downloading of new applications and the use of applications that have already been downloaded.

To prevent other users—your children, another family member, or outsiders—from downloading programs or using programs that have already been downloaded but have been determined by you to be harmful for them, use the special Parental Control feature to block those options.

Open the Applications tab in Dr.Web Parental Control. You will see a list of all the applications installed on your device. Select the applications you want to block access to.

This is only sufficient to prevent anyone who does not know the Dr.Web account password from using already installed applications. You must also prohibit anyone from downloading new applications to your device.

Go to the Components tab of the Parental Control. Check the box next to Dr.Web settings.

In the Components tab of the Parental Control, select Play Market.

And then if anyone attempts to download a new application, this window will appear:

The URL filter in Dr.Web Security Space for Android 12 is disabled by default. We recommend that you configure it right after you install Dr.Web and that you password-protect access to it using Dr.Web Parental Control—this will prevent those close to you from visiting malicious and fraudulent websites.

In addition, you can configure website blacklists and whitelists or block access according to thematic groups of sites.

Only then will you be able to keep your children (or anyone else who has access to your device) from disabling the blocking options in the URL filter and visiting webpages you deem to be undesirable; they will be protected from fraudsters’ attempts to lure them to dangerous sites.

To prevent anybody from tampering with the settings you established for the URL filter.

In the Parental Control's Components tab, check the box next to URL filter.

When trying to open a website from the banned websites list, the user will see this window.

Learn more about the URL filter settings from our video tutorial.

Send the trusted friends on your Dr.Web Anti-theft contact list a memo containing the SMS commands used to remotely control the Anti-theft in emergency situations—that way they’ll know how to help you when needed.

Download

In the application's main menu, select Anti-theft. In the Configuration Wizard window, enter and confirm a password. If necessary, create a friends list (a list of trusted numbers).

More detailed information about configuring the anti-theft can be found in the corresponding section of the documentation.

Then you can adjust anti-theft security parameters: set blocking conditions and the actions that the program will perform if those conditions are met. More information about this can be found here.

To activate the anti-theft, use the previously specified password.

There are three ways to choose from to unlock the device depending on the version of Dr.Web for Android you use and availability of the friends list.

  • If you are using Dr.Web for Android 7.0 and higher, use the special service at.
  • If, when configuring the anti-theft (any version), you created a list of friends, you can disable the anti-theft by sending a corresponding SMS command from a trusted number. For more information about SMS commands, please follow this link.
  • If you use Dr.Web for Android 6.0 and didn't create a list of friends, you need to send a request to Doctor Web's Technical Support Service. In your request, you will need to provide the following information:
    • Your Dr.Web serial number
    • a photo of the box, warranty card, or other document that concerns the blocked device and contains a readable IMEI.

Launch Dr.Web for Android and select Statistics. The statistics window displays the number of processed files and information about all actions performed by the anti-virus components. It is possible to reset the statistics (Menu→Clear statistics), or save the log to a file (Menu→Save log).

Launch Dr.Web for Android and select Statistics. Tap Menu and choose Save log on SD card. The DrWeb_Log.txt file will be saved into the /Andoroid/data/com.drweb/files/ directory and a corresponding notification will be displayed. If you want to send a support request, use the web-form at https://support.drweb.com/support_wizard/. To attach a file to your request, tap Browse, select the file you need and press Open. To send the request, tap the Send button.

To avoid downloading a huge amount of data via the mobile Internet, temporarily disable it for an application. To do this:

  • run Dr.Web;
  • open the Firewall component;
  • click on the “Applications” tab;
  • select the application you need;
  • in the “Access to data transfer” section, click on "Mobile Internet" so that it becomes inactive.

When you need to download a major update, for example, via free or home Wi-Fi, you can use this same method to allow the application to use mobile traffic to connect to the Internet.

To view applications whose network access parameters were specified in the Firewall:

  • run Dr.Web;
  • open the Firewall component;
  • click on the “Applications” tab;
  • take note of the applications marked with the red gear icon.

If present, this icon indicates that the application settings in the Firewall were changed or that an active rule was set for it.

The floating window containing traffic-usage information is disabled by default because it takes up screen space, which may not always be convenient when working with a mobile device. When no acute need to control traffic exists, the window can be disabled, but when the amount of traffic and where it is coming from is important to know, it is better to have this data on view.

To enable the display of the floating window:

  • run Dr.Web;
  • open the Firewall component;
  • click on the “Limit” tab;
  • select "Current traffic information";
  • place the floating window on the screen so that it does not bother you while you are working with your mobile device.

Immediately after this option is selected, the floating traffic-information window will appear; in the future, it will appear on top of other windows.

For user convenience, network traffic-usage information is displayed in two ways.

To obtain full information on application network activity while the Firewall is in operation:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Applications" tab.

To view data pertaining to an application you are interested in, select the application from the list—the settings window, containing complete information, will open.

The user can also control this information via the floating window—we've described how to enable it here.

If you need to prevent an application from accessing a website, you can do this on the Dr.Web Firewall’s "Traffic" tab:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Traffic" tab;
  • select the application you want to prevent from accessing the website;
  • from the drop-down list containing connections used by applications, select the connection that needs to be blocked;
  • you will see a pop-up menu that lets you add an “allow” or “block” rule. Select "Add blocking rule".

The firewall will now automatically block access to this resource.

If you want to restore access to a previously blocked resource, you can do this by removing the corresponding blocking rule.

You can also explicitly specify an address that you don’t want any programs connecting to. To do this:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Applications" tab;
  • select the program you want to keep from accessing the website;
  • in the newly appeared window, in the "Rules for IP addresses and ports" section, select "Block connections from list";
  • click on "Add rule", and in the "New rule" window, specify the server address and the connection port you need to block access to;
  • click OK to finish creating the rule.

The firewall can restrict the use of mobile traffic and, if necessary, block an application's access to the Internet via a selected connection type: Wi-Fi, mobile Internet, and in roaming.

To configure the connection types that applications can use to connect to the Internet:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Applications" tab;
  • select the application you need;
  • in the "Access to data transmission" section, specify the connection types that the application can use to connect to the Internet.

To limit the use of mobile traffic:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Limit" tab;
  • select "Limit mobile Internet";
  • in the newly appeared window, indicate how much mobile traffic (in megabytes or gigabytes) you can use for a specific period (day, week, or month), and click “OK”.
  • you will see a window where you can specify the amount of traffic you’ve already used prior to the current moment—if you’ve already used some traffic from the current period (for example, you installed Dr.Web in the middle of the month). Specify the amount that you have used, and click “OK”.

With this option, you’ll find it very convenient to receive notifications informing you that you are reaching your limit. To enable these notifications, select the “Notifications” checkbox in the “Limit” tab.

Since limited Internet plans are usually offered for a specific amount over a specific period (for example, 100 MB per 24 hours or 5 GB per month), the traffic limitation option can be configured to prevent users from suddenly and significantly exceeding their usage limits.

To configure a limit for the mobile traffic you use

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Limit" tab;
  • select "Limit mobile Internet";
  • in the newly appeared window, indicate how much mobile traffic (in megabytes or gigabytes) you can use for a specific period (day, week or month), and click “OK”.
  • you will see a window where you can specify the amount of traffic you’ve already used prior to the current moment—if you’ve already used some traffic from the current period (for example, Dr.Web was installed in the middle of the month). Specify the amount that you have used, and click “OK”.

With this option, you’ll find it very convenient to receive notifications informing you that you are reaching your limit. To enable these notifications, select the “Notifications” checkbox in the “Limit” tab.

Two of the tools incorporated into the Firewall can be used to view current network activity.

The first one is the floating window, which, in minimised format, displays the total amount of traffic used and, in expanded format, displays the list of applications currently using an Internet connection.

If the floating window is disabled, do the following to get the latest network activity information:

  • run Dr.Web;
  • open the Firewall component;
  • click on the Firewall's "Traffic" tab.

Here, the user can find information about the applications and services currently using an Internet connection and the amount of traffic they are using.

If, for some reason, you have to completely block an application’s access to the Internet, the best solution will be to prevent the application from being able to transfer data.

To limit any kind of network activity for an application, do the following:

  • run Dr.Web;
  • open the Firewall;
  • click on the "Applications" tab,
  • select the program whose Internet access you want to limit;
  • in the newly appeared window, in the "Access to data transmission" section, disable the use of Wi-Fi, mobile Internet, and roaming for each application in the list.

To create a rule that restricts or allows an application to engage in any kind of network activity, do the following:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Applications" tab,
  • select the program for which you want to create the rule;
  • in the newly appeared window, go to the "Rules for IP addresses and ports";
  • create an “allow” or “block” rule, as described below.

To create a blocking rule:

  • select "Block connections from the list" from the drop-down list;
  • click on "Add rule";
  • in the newly appeared window, enter the IP address (in the ххх.ххх.ххх.ххх format) and the number of the port (e.g., 225) to which you need to block access;
  • click "OK".

If necessary, you can repeat this operation for all the addresses you want to block access to. All other connections will be enabled by default. This operation mode can conveniently be called "Using the blacklist".

To create an allowing rule:

  • select "Allow only the connections from the list " from the drop-down list;
  • click on "Add rule";
  • in the newly appeared window, enter the IP address (in the ххх.ххх.ххх.ххх format) and the number of the port (e.g., 225) to which you need to allow access;
  • click "OK".

If necessary, you can repeat this operation for all the addresses you want to have access to. Please note that all other connections will be disabled by default. This operation mode can conveniently be called "Using the whitelist".

For each application that uses Internet access, the Firewall collects statistics related to incoming and outgoing traffic.

To view statistics:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Applications" tab;
  • select an application you are interested in, and in the newly opened window, go to the "Statistics" section.

Here, users can find complete traffic information (incoming and outgoing) for the application and a network-usage diagram. Users can see how much data the application received during a defined period.

If you need to delete an existing rule:

  • run Dr.Web;
  • open the Firewall component;
  • click on the "Applications" tab;
  • select the application for which you want to change the rule;
  • in the list of rules visible in the newly appeared window of the "Rules for IP addresses and ports" section, tap the line that you want to delete, and drag it in any direction. The line will switch to the choice "Edit" or "Delete";
  • click on "Delete" to remove the rule or on "Edit" to replace it with a new one.

All Firewall actions are logged and recorded in the Firewall Log. The report contains the following information about applications and actions involving them:

  1. Application name.
  2. IP address, port, and protocol via which the data was exchanged.
  3. Date and time of connection (for TCP) or time taken to receive data packets with the corresponding amount of traffic (for UDP). For example: 21/11/2017 22:19:39 — 21/11/2017 22:19:42.
  4. Local address and local port. For example: src: 192.168.0.102:55512.
  5. Incoming and outgoing traffic (bytes) or the number of blocked packets. For example: in:124 out:79 or blocked packets:1.
  6. The identifier of the application on the device associated with this traffic (User ID). For example: uid=10011.
  7. Number of network congestion incidents (for TCP only). For example: traffic jam=0. Traffic congestion is a special situation when a client program fails to offload a TCP buffer, and that can be the cause of data transfer slowdowns over the network.

To open the Firewall Log, run Dr.Web, open the firewall, and then click on the icon in the form of the vertical ellipsis. Select "Log".

Note that data related to application network activity is stored in a separate Application log that is created separately for each application.

After this, the Firewall starts operating. By default, all network activity is allowed except the use of the Internet in roaming. To manage traffic at your own discretion, you will need to configure the Firewall.

Since monitoring and recording all network application activity is one of the main tasks of the Firewall, the Application Log stores all the information about application-specific network activity:

  1. Time an event occurred
  2. Resource name
  3. Resource IP address
  4. Protocol via which the connection was established
  5. Connection status
  6. Amount of incoming traffic
  7. Amount of outgoing traffic

To access the Application log, do the following:

  • run Dr.Web;
  • open the Firewall;
  • click on the "Applications" tab;
  • select the application you need, and in the newly appeared window, click on the icon that looks like a vertical ellipsis. Select "Application Log".

The Call and SMS Filter protects against phishers and vishers. But fraudsters can ask children to disable the restrictions their parents have established in this component.

Dr.Web Parental Control will reliably protect your children provided you ensure that they cannot tamper with the Call and SMS Filter settings.

In the Parental Control's Components tab, check the box next to Call and SMS Filter.

This setting won't allow the user to bypass Call and SMS Filter restrictions, and the user will receive calls and SMS according to the settings established for this component. For example, if the Filter is configured to allow calls and messages from the whitelist only, the user will only receive calls from numbers on that list.

When trying to sign in to the Filter settings, the user will see this window:

Learn more about the Call and SMS Filter settings from our video tutorial.

Dr.Web for Android doesn't block outgoing calls.

The anti-virus places suspicious and infected files into the quarantine folder. Suspicious files are quarantined to be sent to Doctor Web's virus laboratory for analysis, infected ones are isolated if curing is not possible for some reason.

Solution:

It defends your Mac from all types of malicious programs—including those created specifically for OS X. With the growing popularity of OS X, malware tends to target specifically this operating system. Incidents involving large-scale botnets comprised of infected Macs did occur: such Trojans as BackDoor.Flashback.39, Trojan.SMSSend and Trojan.Yontoo.1 still pose a threat to unprotected machines.

With Dr.Web for OS X., you can protect your system from these and many other malicious programs created to infect Macs as well as other operating systems. However, bear in mind that, while an update containing a corresponding virus definition has arrived, no anti-virus can protect your Mac against new malware, which hackers tested against latest versions of anti-virus engines. To protect against such malicious programs, you need to use advanced security tools and, of course, be careful when you visit certain sites.

Yes. The first virus for an Apple computer was created in 1982. The first virus for Mac OS X (Mac.Leap) appeared in 2006. In early 2009, the Trojan Mac.Iservice infected machines that comprised the iBot zombie network. In 2012, half a million of computers were connected to the botnet created by the Trojan BackDoor.Flashback. It was Doctor Web who first discovered this zombie network.

An attacker does not necessary need to hack into your computer to install malicious software. In most cases, unwanted programs get onto Macs due to careless of users when they visit legitimate sites, such as news portals. They can be compromised, so that infection gets onto computers of visitors regardless of their OS—in most cases, the target platform is detected and selected automatically.

Two simple conditions must be met for a system to get infected with BackDoor.Flashback.39: Java Virtual Machine must be installed in the system, and a user must load a compromised webpage in the browser.

Trojan.SMSSend family programs can be easily downloaded from various websites under the guise of a useful application. Today, adware for OS X is also rather common. For instance, Trojan.Yontoo.1 gets onto a Mac, if the user agrees to download and install a browser plug-in from certain sites, or downloads it under the guise of a media player, a program to improve video playback quality, a "download accelerator", etc.

There are also e-mail and removable data storage devices—the traditional media that spread malware with no regard to the operating system.

It is a botnet of infected Macs which took shape with emergence of the Trojan Mac.Iservice in January 2009. To date, it has several thousand computers and has managed to manifest itself in a number of DDoS-attacks.

For evaluation purposes, you can use the trial version. Download the distribution from Doctor Web's site at download.drweb.com/demoreq. The period of a demo license is 30 days.

You can also use the free scanner Dr.Web Light for OS X. The scanner incorporates state-of-the-art technologies to detect and eliminate viruses. You can use it to check your system, whenever you need to. However, Dr.Web for OS X is a more feature-packed product as compared with Dr.Web Light for OS X. It includes Dr.Web SpIDer Guard file monitor to scan files in real time.

According to the documentation, OS X 10.7 and above are supported.

Dr.Web for for OS X protects against viruses whose definitions are present in the Dr.Web virus database. They can be written to infect OS X as well as other platforms.

The non-signature detection technology Origins Tracing and heuristic analyser help neutralise threats yet unknown.

Every day the Doctor Web virus monitoring service collects more than 250,000 new malicious programs, the most dangerous of which have been developed by professional virus writers who are members of criminal organizations. These programs focus on stealing money from single companies (or a series of “targeted” companies); the creators of these programs know what security systems are in use, and devise their malware accordingly.

It is commonly believed that by installing a protection system on a mail server, one can reduce the inflow of spam and the number of viruses in a company network, and speed the delivery of important emails. But apart from solving these problems, a modern mail server anti-virus also affords the opportunity to delete previously unknown malicious programs from mailboxes. Only by installing an anti-virus on a company mail server can one escape situations in which the server becomes a source of infection. An anti-virus can’t protect a server file system, because such anti-viruses can’t cure databases, including mail server databases.

Any mail server restricts the capabilities of the anti-virus that is installed on it. For example, the widespread MS Exchange mail server transmits for analysis only parts of an email, not the whole thing, which significantly complicates the analysis, including the analysis for spam. For increased effectiveness, it is strongly recommended that mail traffic filtering be transferred to a separate server that is independently capable of receiving and transmitting email messages. This simultaneously improves the quality of scanning and (in some cases) reduces the cost of licensing the mail server. For this purpose, an additional Dr.Web component—SMTP Proxy, which is the part of Dr.Web Mail Security Suite—should be used. This component extends the product’s features, e.g., it allows source addresses to be checked and system user authorization and many other features to be employed.

The latest malicious programs, undetected by all heuristic mechanisms, reach the virus monitoring laboratory, and thus their victims, only after criminals have begun spreading them.

It is imperative to take into account the probability of criminals being able to bypass a company’s security systems and access its network (or employees’ PCs) and also the possibility of criminals being able to impact the protection systems in use, with the goal of stopping their operation.

To minimize risks to mail servers in particular, user mailboxes should be scanned regularly with an anti-virus to check for the presence of previously unknown malicious programs.

No anti-virus can detect the newest malicious programs 100 percent of the time. Even tests designed to detect malicious programs created after the latest anti-virus update say nothing about an anti-virus’s capacity to reveal the ‘infection’ created by criminals familiar with the anti-virus. Such anti-virus programs will not be detected by an anti-virus right up to the moment the necessary update is received.

That’s why the choice of an anti-virus should not be based on “test” results, but on an understanding of the following features of an anti-virus system:

  • An anti-virus has to have a reliable system of self-protection— criminals must not be able to disable the anti-virus (or one of its components).
  • Anti-virus updating and control systems must be completely under the control of the anti-virus’s self-protection system and must not use system components that are not under its control.

Once a company’s computers fall into a botnet, they often become a source of spam, and that harms the company’s reputation among its partners. Using Dr.Web Mail Security Suite and Dr.Web Desktop Security Suite will significantly reduce a company’s risk of becoming compromised by being blacklisted and disconnected from the Internet for acting as a spam bot.

A system for scanning mail traffic must be installed on the server as well as on the work stations, because incoming and outgoing messages go not only through a company’s mail server, but also directly through employees’ PCs (via SMTP, pop3/imap4 and closed links). In addition, the mail server (or the programs installed on it) can create mailings, including unwanted messages.

For evaluation purposes, you can use the trial version. Download the distribution from Doctor Web's site at http://download.drweb.com/demoreq. The demo license period is 30 days.

You can also take advantage of the Dr.Web LiveDemo remote testing service by filling out an application at https://download.drweb.com/live_demo. It should be noted that when testing a product via Dr.Web LiveDemo, the accompanying step-by-step instructions on how to test the product’s basic functionality are tremendously helpful.

The following routes of infection are typical for embedded systems:

  • An infected company intranet, if embedded systems can be accessed from it;
  • Vulnerabilities that exist due to the absence of security updates;
  • Employee removable data-storage devices (including those that have been used for purposes other than embedded systems maintenance);
  • Hacker-owned removable data-storage devices, if the hackers have unauthorized access to ATM equipment compartments;
  • Internet sites visited by company personnel during maintenance periods.

Therefore, anti-virus protection that includes a traffic control module and an access restriction module for removable data-storage devices and Internet resources is essential for embedded systems to operate normally.

Yes. Dr.Web ATM Shield can be used not only for conventional OSs—Windows® XP Professional, Windows® Vista, Windows® 7 and Windows® 8—but also for Windows® XP Embedded, Windows® 7 Embedded, and Windows® 8 Embedded.

It must be remembered that some devices may lack various operating system components. This is a feature of Embedded OSs.

Dr.Web ATM Shield was developed with low-end platforms in mind¬¬¬. Dr.Web ATM Shield can run on an embedded device with just 512 MB of RAM.

It should be noted that Dr.Web products, including Dr.Web ATM Shield, are distinguished by compact virus databases and small size updates that make it possible to protect remote devices with ‘narrow’ Internet channel or a company network.

Dr.Web ATM Shield is required in all embedded devices that are subject to the requirements of PCI DSS and STO BR RF, and in all systems that can be infected through unknown vulnerabilities.

A peculiarity of the way embedded devices work (including ATMs) is that you cannot carry out updates (specifically, updates to the OS and applications launched on them) on them that may at some point require a device reboot as soon as update data is available — even if the system is busy.

Therefore, Dr.Web ATM Shield has two types of updates: virus database updates (that don’t require system restarts) and updates for Dr.Web ATM Shield’s basic components, including the drivers. Basic components updates, carried out when new types of malicious programs appear, may require a reboot of the protected device.

Because updates that potentially require a system restart can only be carried out during routine maintenance checks, it’s essential for employee home and work PCs to be protected by an anti-virus in order to prevent the newest malicious programs from penetrating removable data-storage devices used for routine maintenance.

Dr.Web ATM Shield conforms to the anti-virus program requirements of the Federal Law on Personal Data (No. 152-FZ), FSTEC Russia’s orders No. 17 and No. 21, and other regulatory demands in the sphere of personal data protection.

When applied, Dr.Web ATM Shield meets the anti-virus program requirements of PCI DSS v2.0 and v3.0 standards.

PCI DSS standards require only the fact that an anti-virus is being used and don’t make any claims about the functionality and features of the solution being used. Moreover, these standards stipulate the requirements for protecting devices in general, not their separate components. Therefore, the certificate isn’t provided for anti-viruses.

‘But Symantec has a PCI DSS certificate of compliance!’

Symantec has more than just anti-viruses in its portfolio. And the certificate you mentioned doesn’t belong to anti-virus software.

No, you cannot, because Dr.Web CureNet! requires the Wizard to be installed on a LAN PC. This is, however, a great advantage of Dr.Web CureNet! — and you can launch the utility from USB data storage

In order to update Dr.Web CureNet!, you need to log into the Dr.Web CureNet! user personal area and download the latest version from there. Since a PC from which a LAN is scanned might not have an Internet access or its an access blocked by the provider, we strongly recommend to download an actual Dr.Web CureNet! version before scanning your network. Unique Dr.Web CureNet! distribution files are generated for each user.

If the Dr.Web CureNet! serial number is not registered yet, please register it on this page. At the final stage of registration a link to download Dr.Web CureNet! personal distribution file will be generated.

If the Dr.Web CureNet! serial number is already registered, go to Dr.Web CureNet! personal area and download your Dr.Web CureNet! personal distribution file.

You can register it on this page. At the final stage of registration a link to download Dr.Web CureNet! personal distribution file will be generated.

Register the serial number for the valid Dr.Web Enterprise Suite license.
You are allowed to use Dr.Web Enterprise CureNet! free of charge as long as the Dr.Web Enterprise Suite serial number is valid. However, your Dr.Web CureNet! personal distribution file will only be valid for 1 day. Therefore, you will have to register the serial number every time you need Dr.Web CureNet!. Every time a new Dr.Web CureNet! personal distribution file will be generated for you.

Dr.Web CureIt! is used to scan individual PCs and can fulfil needs of small companies. However, if there are many computers in the company, scanning each of them will take a lot of system administrator time and distract employees form their work. Dr.Web CureNet! allows performing scanning remotely over a network in the background so that a user can remain unaware of it. System administrator can operate from the single computer thus minimizing anti-virus influence on the performance of computers being scanned.

Dr.Web Enterprise Suite is designed to permanently protect the network. It is a very powerful product rich of numerous features. In order to use Dr.Web Enterprise Suite one has to deploy it on all hosts while with Dr.Web CureNet! you won’t need to deploy or install anything. Moreover, scanners will remove themselves from target hosts upon completion of scanning.

Download the program distribution demo file to evaluate Dr.Web CureNet! Remote curing is not available in demo version so you need to purchase a license to download fully functional Dr.Web CureNet! version.

The product is licensed per number of workstations on which scanning followed by curing will be performed for 10, 30 or 365 days of use. Such license periods are used because Dr.Web CureNet! is designed for regular scanning but not to provide resident protection.

Yes, you can. Dr.Web CureNet! is designed to operate in a network environment protected with other security products.

No anti-virus can detect all malicious programs currently in the wild, let alone the fact different anti-viruses vary significantly in terms of detection and curing capabilities. The number of viruses in the Internet is huge and new species appear very quickly. Regular local network “health” checks with Dr.Web CureNet! will help you verify reliability of your anti-virus software and cure computers in emergency situations when your anti-virus fails to neutralize a threat.

You can use Dr.Web CureNet! for regular scans of your local network hosts if they are not protected by any other anti-virus, or if you suspect that the installed product doesn't detect some viruses.

Caution! Dr.Web CureNet! is not designed to provide constant anti-virus protection but perform only one-time scans. It doesn’t prevent malicious programs from infiltrating into a network between scanning sessions.

The user is displayed a notification informing them that they can continue to work in the enhanced protection mode (while other operations will be unavailable) or run Dr.Web CureIt! in the standard mode. When running in the enhanced mode, you can't switch to the standard mode until scanning is completed.

Self-protection of the Dr.Web anti-virus is activated at an early startup stage. New stealth algorithms allowing the utility to remain unnoticed by viruses rule out the possibility of blocking its operation before this point.
