•Licensed period for the product

•List of components the user is allowed to use (e.g. the anti-spam feature can be enabled only in the «Anti-Virus&Anti-Spam» version)

•Other restrictions (e.g. users number limitation for the license)

A valid license key file satisfies the following criteria:

•License is not expired

•The license applies to all components of the product

•Integrity of the license key file is not violated

If any of the conditions is violated, the license key file becomes invalid, Dr.Web stops detecting the malicious programs. License violation is registered in the Windows Event Log and in the text log of plug-in.
