Win 7 beta and Kasperski 8.0 anti-virus beta for Win7

I've been running the beta since it came out.......also Kasper 8.0 beta since it came out.
Well, Kasper recently I went to delete it.

My Win 7 CRASHED AND BURNED. So far I have not been able to revive it.

I see no mention of these items together on this site. I do not know if this is true for the RC.
