Licensing

Permissions to use Dr.Web for Linux are granted by the license purchased from Doctor Web company or from Doctor Web partners. License parameters determining user rights are set in accordance with the License agreement which the user accepts during product installation. The license agreement contains information on the user and the vendor as well as usage parameters of the purchased product, including:

•Other restrictions (for example, number of computers on which the purchased Dr.Web for Linux is allowed for use).

For evaluation purposes users may also activate demo period. After successful activation, demo period provides users with full functionality of the solution for the whole activated period.

Each Doctor Web product license has a unique serial number associated with a special file stored on the user computer. This file regulates operation of Dr.Web for Linux components in accordance with the license parameters and is called a license key file. Upon activation of a demo period, a special key file, named a demo key file, is automatically generated.

If a license or a demo period are not activated on the computer, Dr.Web for Linux components are blocked. Moreover, updates to virus databases cannot be downloaded from Doctor Web update servers. But you can activate Dr.Web for Linux by connecting it to the central protection server as a part of the anti-virus network administered by the enterprise or Internet service provider. In this case, operation of Dr.Web for Linux and updating are managed by the central protection server.

After a license is purchased, updates to product components and virus databases are regularly downloaded from Doctor Web update servers. Moreover, if the customer encountered any issue when installing or using the purchased product, they can take advantage of technical support service provided by Doctor Web or Doctor Web partners.

You can purchase any Dr.Web product as well as obtain a product serial number either on the online store or from our partners. For details on license periods and license types, visit the Doctor Web official website at http://www.drweb.com/.

License registration is required to prove that you are a legal user of Dr.Web for Linux and activate Dr.Web for Linux functions including virus database updating. It is recommended to register the product and activate the license once installation completes. A purchased license can be activated in one of the following ways:

During activation, it is required to enter the serial number. The serial number is supplied with the product or via email when purchasing or renewing the license online.

If you have used Dr.Web for Linux in the past, you may be eligible for a 150-day extension to your new license. To enable the bonus, enter your registered serial number or provide the license key file. Otherwise, if you select an option to renew the license but do not provide the previous license data, the period of license validity will be reduced by 150 days.

If you have several licenses for using Dr.Web for Linux on several computers, but choose to use the product only on one computer, you can specify this and, hence, license validity period will be automatically extended.

To obtain a demo period for 3 months, register on the Doctor Web official website and provide the requested personal data. After registration completes, you will receive an email with a serial number for Dr.Web for Linux activation. Demo period for 1 month can be received in the Registration wizard window of License Manager. To obtain a demo period for 1 month, you do not need to provide your personal data.

You can start registration or obtain a demo period from the License Manager window at any time by clicking the Get new license... button on the page with information on the current license.

To activate a license using the serial number or request a demo license, a valid Internet connection is required.

Another demo period for the same computer can be obtained after a certain time period.

When a demo period or license is activated via License Manager, the key file (license or demo) is automatically generated on the local computer in its target directory. If you register on the website, the key file is sent by email and you need to install the key file manually.

If a key file is lost but the existing license is not expired, you must register again by inputting the personal data you provided during the previous registration. You may use a different email address. In this case, the key file will be sent to the newly specified address.

The number of times you can request a key file is limited. One serial number can be registered no more than 25 times. If requests in excess of that number are sent, no key file will be delivered. To receive a lost key file, contact technical support, describe your problem in detail, and state personal data you entered upon serial number registration. The license key file will be sent by email.
