Key File

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

Licensed period for the product
List of licensed anti-virus components
Other restrictions (for example, the number of remote computers allowed for simultaneous anti-virus check)

There are tree types of key files:

License key file is purchased with Dr.Web and allows you to use the software and receive technical support. Parameters of the license key file are set in accordance with the software's license agreement. The license key file also contains information about the user and seller of the software.
Demo key file is used for evaluation of Dr.Web. Demo license is completely free and provides full functionality of the software but has limited duration – 30 days (if it is a promotion license key file — 3 months).

 

Note

Demo key files for the same computer cannot be received more often then once in 4 months. For a promotion license key file — only once a year.

 

Temporary key file is used if you do not install a valid key file during installation. This key file provides full functionality of Dr.Web, however updating is not available until you install a license or demo key file. Furthermore, the My Dr.Web and Update items of SpIDer Agent menu will be inaccessible.

A valid license key file satisfies the following criteria:

License is not expired
All anti-virus components required by Dr.Web are licensed
Integrity of the license key file is not violated

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