i personally use norton, just becasue of free yearly updates. McAffe doesnt do that but its better. It once cleaned my machine from over 700 viruses. Well, did not xactly saved me, i already had every single one of them
But it cleaned it up! It had some problems with other viruses though, so i spend most of my time getting rid of viruses by hand, i call it AMIGO-FREESTYLE
lol.
Anyways, what i would suggest, is go 2 ur task manager, and look for suspicious tasks. Usually they would use a lot of resources.. ram/cpu. But sometimes they dot really bother doing that, and bringing users attention to them. Sorry for this essay
lol. Just find suspicious tasks, and go on google, look it up, and c 4 urself. Then its Cleaning-Time!!!
