Licensing

Permissions to use Dr.Web for Linux are granted by the license purchased from Doctor Web company or from its partners. License parameters determining user rights are set in accordance with the License agreement (see https://license.drweb.com/agreement/), which the user accepts during product installation. The license 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 a demo period. If activation terms of the demo period are complied with, a user gains rights to use Dr.Web for Linux with full functionality 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 the 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 (including cases when a validity of a purchased license of a demo period is expired), anti-virus functions of the Dr.Web for Linux components are blocked. Moreover, updates for the Dr.Web virus databases and components cannot be downloaded from Doctor Web update servers. However, you can activate the 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 the product 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 its partners.

You can purchase any Dr.Web product as well as obtain a product serial number either from our partners (see the list of partners on https://partners.drweb.com/) or in our online store https://estore.drweb.com/. For details on license periods and license types, visit the Doctor Web official website at https://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.

To renew the license, enter your registered serial number or provide a previous license key file. Otherwise, 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 Dr.Web for Linux 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.

The Registration Wizard of License Manager opens upon the first Dr.Web for Linux startup (usually Registration Wizard starts once installation of Dr.Web for Linux completes). 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 the registration wizard is unavailable (for example, due the absence of operating system GUI), you can use thecommand of license management of the command line interface drweb-ctl, which allows to obtain the demo key file or license key file for the serial number of the license registered (including the serial number of demo period, obtained by email). The description of drweb-ctl can be found in user manual.

•At Doctor Web official website https://download.drweb.com/doc/ (Internet connection is required).

•You can view a PDF file in the /opt/drweb.com/share/doc directory (the suffix in the name indicates the language).

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