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 When the installer detects an outdated version, it will remove it.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.

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

  3. The Registration Wizard dialogue will open. Enter your first serial number.

    #drweb

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

    #drweb

    To add the terms of your current license and new license together, select I will specify the previous license, and in the subsequent dialogue, enter the serial number of your current license.

    #drweb

    #drweb

    If the license's validity period is three months or longer and the new license will be valid for at least 12 months, 150 days will be added to your new license.

    • If your have a Dr.Web license whose period was three months or longer but the license already expired, select I don't have previous license and in the window that opens enter its serial number or specify its key file.

      #drweb

      #drweb

    • If you do not have such licenses, click on the link I do not have any previous license.
  4. Fill out the registration form, and click Next.

    #drweb

  5. Your license has been activated successfully. Press OK.

    #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.

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.

Single-user licenses and OEM
