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 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:

•List of components licensed to the user.

•Dr.Web for Linux license period.

•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 you correctly activate the demo period, you gain the rights to use the installed copy of 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 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 Dr.Web for Linux 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 centralized 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 centralized protection server.
