Licensing

To use Dr.Web, activate a license. To use Dr.Web for a long period of time, activate a license. You can purchase a license with the product or on the Doctor Web official website. A license allows to take advantage of all product features during the whole period. Parameters of the license key file are set in accordance with the software license agreement.

If you want to evaluate the product before purchasing it, you can activate a demo period. It provides you with full functionality of the main components, but the period of validity is considerably restricted.

Demo period is available for:

•For 3 months. For that, register on the Doctor Web official website and receive a serial number.

•For 1 month. For that purpose, no serial number is required and no registration data is requested.

Key File

The use rights for the Dr.Web are specified in the key file.

The key file has the .key extension and contains the following information:

•List of licensed anti-virus components

•Licensed period for the product

•Availability of technical support for the user

•Other restrictions (for example, the number of remote computers allowed for simultaneous anti-virus check)

A valid key file for Dr.Web satisfies the following criteria:

•License is not expired

•All anti-virus components required by Dr.Web are licensed

•Integrity of the key file is not violated

If any of the conditions is violated, the key file becomes invalid and Dr.Web stops detecting and neutralizing malicious programs in files, memory and email messages.

If during Dr.Web installation, a key file was not received and no path to it was specified, a temporary key file is used. Such a key file provides full functionality of Dr.Web. However, on the SpIDer Agent menu, My Dr.Web and Updater items are not available until you either activate a license or demo period or specify a path to the valid key file via License Manager.

It is recommended to keep the key file until the license or demo period expires.
