No solutions so far I see, I will probably change my anti virus then.
Btw in task manager I saw, that svchost.exe is always doing some activity, and taking about 5-10% cpu, is this normal, there might be a reason why kav is showing those messages. In older windows 7 builds I was getting these messages too, but very rarely once a day or so, but now its like every 20 seconds. Can someone answer me why?
