Kaspersky probs

Well, Kaspersky is probably the best Antivirus. Whenever I install, then restart it crashes my PC, I mean 1GB RAM, Core 2 duo E6400 @ 2.13 GHz
and cant’ handle Kaspersky, but can handle all latest games mostly.
Whats wrong?
Answer #1
Have you unistalled it and try too install it again ?
And yes i think it is the best anti virus
EDIT: I dont see why you can run it, I use kaserpsky with these specs…
1.40 Ghz
256mb ram
And your specs are much better
