Licensing

The rights to use Dr.Web for Linux are granted by a license purchased from the 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 Dr.Web for Linux installation. The license contains information on the user and the vendor as well as usage parameters of the purchased product, including:

•a list of components licensed to the user;

•a Dr.Web for Linux license period;

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

Each Doctor Web product license has a unique serial number associated with a special file stored on the local 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.

You can activate a demo period for evaluation purposes. Upon activating the demo period, you gain the right to use the installed copy of Dr.Web for Linux with full functionality for this entire period. At that, a special key file named a demo key file is automatically generated.

If there is no valid license or a demo period is not activated (including cases when a license purchased earlier or a demo period is expired), anti-virus functions of Dr.Web for Linux are blocked. Furthermore, updates for the Dr.Web virus databases cannot be downloaded from Doctor Web update servers. However, you can activate the Dr.Web for Linux by connecting it to a centralized protection server as a part of an anti-virus network administered by an enterprise or an internet service provider. In this case, anti-virus functions and updates of the product instance installed on the computer are managed by the centralized protection server.
