It seems that Kaspersky Lab they took as an example Microsoft, when they decided to offer free, until the end of the year, anti-virus for Windows 7.

This decision of Kaspersky, to offer license free beta is welcome for users who are not Kaspersky customers. The strangest part is for users who have bought licenses by Kaspersky and which must be extended until the end of the year. It is known that Kaspersky offers licenses for limited periods.
I bought a Kaspersky Anti-Virus license almost a year ago. Expiry date keydegree is somewhere at the end of next month. When I installed Kaspersky Anti-Virus Beta for Windows 7, I had a little surprise.

Incorrect Activation Code.

I contacted support from Kaspersky Lab and I told them that I have a license bought from them and I would like to activate it on Windows 7 / Kaspersky Anti-Virus 8.0 Beta.
Response:

Hello,
We are not support Windows 7 before official release of this OS.
Best regards,
Kaspersky Lab Support Team

Good like that. They do not offer support for Windows 7, and we do not extend licenses until the final version is released. More accurate, Kaspersky Anti-Virus is free for all users until the end of the year. As far as I understand, Kaspersky Anti-Virus for Windows 7 is also compatible with Windows XP & Vista. :)
I wonder which Windows 7 user will buy KAV by the end of the year.
