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.

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.

Click Ok.
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.

Version 6.0

Right-click on the Dr.Web icon in the notifications area and select SpIDer Gate–>Settings from the list (if this item is unavailable, you should first switch to the Administrator mode). In the next window, open the Log section and use the slider to set the Extended mode. Press Ok to confirm the changes made.

SpIDer Gate

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.

In fact, the component does not consume traffic. The component checks it while passing it through itself. It processes as much traffic as is generated by the applications that have accessed the Internet and the data that has been received/sent over the network.

Technically, it looks like this:

To check traffic, the anti-virus installs its Internet traffic filters in the protected system and presents itself as a proxy. This filter must be the very first one so that malware cannot process the traffic before it does. For example, in order to conceal that it is transferring data. Third-party monitoring systems also install similar counting filters, but they process traffic after the anti-virus filter because such filters always work consistently. That's why the dwnetfilter process will always be seen as the main consumer of traffic.

On its own initiative, the dwnetfilter component does not connect to the Internet, it only intercepts connections from other applications.

To exclude the false effect that the dwnetfilter component is consuming traffic, you need to exclude it from your traffic control program, if this option is available. It makes no sense to track application traffic separately or their total traffic via the proxy (dwnetfilter).

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.

  • Click on the spider image in the system tray.

Send links to web-site mistakenly rated by the module as undesirable to Doctor Web's laboratory via the web-form on our website.

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...

    • close the "Message filters" window.
  • 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.

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.

The firewall is a program that controls the exchange of data between your PC and the rest of the network. The firewall's main job is to monitor application-generated network activity and prevent hackers or malicious programs from trying to send information from your PC to the network or, vice versa, to accept it from a remote source without authorisation.

In this mode, the firewall can be trained to respond to attempts made by programs to access the Internet.

Upon detecting programs making attempts to access network resources, Dr.Web Firewall checks whether filtering rules have been set for those programs. If the rules haven’t been specified, the user is prompted to either choose a single action for the firewall or create a rule that will be used in the future to process such an application's network activity.

If the firewall is blocking your ability to work with the network, you need to do the following:

  1. To reset the settings, click on the Dr.Web icon in the system tray, and in the Dr.Web menu, select Security Center. Click on the drweb lock icon in the lower-left corner of the window, and then on — drweb gear in the upper-right corner. In the Manage settings section, select Change → Restore defaults, and click on OK.

    Important! This action will reset all of the user settings for all the Dr.Web components, and you will need to configure them again.

    After that, when you try to access the Internet, you may see requests from the firewall (to create a rule, to block once, to allow once). Create allow rules for selected applications by clicking on the button Create rule → Allow → OK.

    For more on how to train the firewall, refer to the documentation

  2. Please contact our technical support service. Attach the report created by the DwSysInfo utility to your request.

    To generate a report:

    1. Download and save the utility on your PC: https://download.geo.drweb.com/pub/drweb/tools/dwsysinfo.exe
    2. Launch the saved dwsysinfo.exe file.
    3. Click on the Generate report button.
    4. Wait for the report-generation process to complete.

To prevent a specific program from connecting to the Internet, create a new rule. Click the Dr.Web icon on the taskbar, and select Security Center → Files and Network. Click on the drweb lock icon.

In the UAC dialogue, click on Yes, and enter the administrator password, if necessary.

Select the Firewall section, and click on Change in the Application rules.

In the newly appeared window, click on the drweb plus icon to add a new rule.

In the next window, enter the path to the application's executable file, and in the drop-down list Launching network applications, select Block. Then select Block all on the Access to network resources list.

Click on OK to have your changes go into effect.

The notification window’s appearance indicates that a processing rule has not been set for the application to which the firewall has reacted. You can do one of the following:

  • Allow once — the application’s network activity is allowed for the duration of the current session. After the PC is restarted or you want to use the program again, the firewall will prompt you to allow the Internet connection again.
  • Block once — this blocks the program’s network activity. Only for the current session.
  • Create rule — when you configure a rule for an application, the firewall will automatically follow this rule. By selecting this option, you will see a window that lets you choose a course of action:
    • Allow network connections for the application on port *port number*
    • Block network connections for the application on port *port number*
    • Allow all network connections
    • Block all network connections
    • Create custom rule — you can create a new firewall rule for the current program.

Note. Always try to create rules to automate the firewall's operation.

To prevent a specific program from connecting to the Internet, you have to create a new rule. Click on the Dr.Web icon on the taskbar, select Security Center → Files and Network and click on the drweb lock.

In the UAC dialogue, click on Yes, and enter the administrator password, if necessary.

Select the Firewall section, and click on Change in the Application rules.

In the newly appeared window, click on the drweb plus icon to add a new rule.

In the next window, enter the path to the application's executable file, and then in the drop-down list Launching network applications, select the action you need:

  • Allow — when you try to run the network application, the firewall will allow this action.
  • Block — when you try to run the network application, the firewall will block this action.
  • Not specified — when you try to run the network application, the firewall will issue a request.

Then select the action you need from the Access to network resources list:

  • Allow all — any network activity will be allowed for the program.
  • Block all — any network activity will be blocked for the program.
  • Custom — you can manually configure all the parameters for the program’s network activity.
  • Not specified — every time the program tries to access the Internet, the firewall will issue a request before connecting.

Click OK to have your changes go into effect.

If the firewall is operating in interactive mode, there is no need to manually configure rules — it is easier to configure access for each application at the time of its initial network activity, directly from the firewall notification window.

Click on the Dr.Web icon on the taskbar, select Security Center → Files and Network, and click on the drweb lock icon. In the UAC dialogue, click on Yes, and enter the administrator password, if necessary.

Then, toggle on the switch to make the Firewall component active — its frame will turn red.

To reset the settings, click on the Dr.Web icon in the system tray. In the Dr.Web menu, select Security Center. Click on the drweb lock icon in the lower-left corner of the window, and then on drweb gear — in the upper-right corner. In the Manage settings section, select Change → Restore defaults, and click on OK.

Important! This action will reset all the user settings for all the Dr.Web components, and you will need to configure them again.

Dr.Web Firewall has three operating modes:

  • Allow unknown connections — all unknown connections are allowed. Protection is not active.
  • Allow connections for trusted applications — rules for known applications (with a valid digital signature) 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 the network, the firewall will prompt the user to choose an action.
  • Block unknown connections — all unknown connections will be blocked without prompting the user.

The user can configure the mode in the firewall's settings. If a rule has already been set for an application, the firewall will follow it.

A parent process is a process or an application that can run other applications. Users can configure rules for parent processes in the window used to create or edit rules for an application with the help of the drop-down list Launching network applications.

Click on the Dr.Web icon on the taskbar, select Security Center → Files and Network, and click on the drweb lock icon. In the UAC dialogue, click on Yes, and enter the administrator password, if necessary.

Select the Firewall section, and click on Show additional settings. In the Operation parameters for known networks section, click on Change. In the next window, the user can define a set of predefined rules for each network connection.

  • Allow all — all packets are allowed.
  • Block all — all packets are blocked.
  • Default rule — rules that describe the most popular network configurations and common attacks (used for all interfaces by default).

Click on the Dr.Web icon on the taskbar and select Security Center → Statistics → Firewall.

This firewall element manages the traffic flow via the selected protocols by allowing or blocking packets according to specified conditions. The packet filter is a basic means of ensuring your computer’s security; it operates independently of applications.

Download this script, save it to your desktop and run by double-clicking on the file. On netfilter.log file will appear on your desktop. Attach this file to the corresponding request, and send it to Doctor Web's technical support service.

Dr.Web Firewall is a Dr.Web anti-virus software component, and it is impossible to install the firewall without the anti-virus.

A digital signature is a code that verifies that a program has been received from a particular source and has not been changed. At the same time, a signed application is not necessarily secure, so users should be careful when installing any software, even signed software.

This could be malware. It is recommended that you launch a full anti-virus system scan.

At home, when you need to protect only one computer against network attacks, the packet filter configuration is not required. The fact is that the firewall database contains a substantial number of rules, and these rules are activated as they are required. If, for any reason, a rule is absent, the firewall will request the action.

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.
