P.S. is the free version really that good or would it be better if I opted for the paid version?
I have tried the free version. My company also uses the paid version. There is not much difference. It's more a matter of being able to set it to run at certain times, update, etc.
I currently use Avast. It seems a lot of people these days are using Avast or AVG. Both have free versions and both are rated pretty high.
As I said I already have McAfee installed because I get it for free from comcast
A friend of mine has the same deal. She just got hit with a really nasty Trojan and has had to shut everything down. The free version she has of McAfee doesn't scan emails or P2P apps. I think her daughter was downloading crap off of Limewire.
I can't speak for AVG, but the free version of Avast works with private messengers, email, P2P, real time..it can do a full scan in boot. For a free app, it covers a lot and hasn't let me down yet.
