Note: All of this is a strong opinion. If you want to fuck me because I'm wrong of any aspect, it's your own fault.
Yeah, there are alot odf AV's out there. You have the worst, N0rton, you have the OK, McAfee, PCillin, AntVir, etc.
But the ultimate BEST and FREE Antivirus is:
Avast!
Reasons:
1. It finds more viruses and deletes them better then N0rton ever will.
2. Updates ONLY TAKE 5 SECONDS ON DIAL-UP!!! (for the virus definitions, that is, program updates take like 5 minutes...)
3. It does not hog up my memory, disk space, or slow down my computer when it is running.
4. IT'S FUCKING FREE!!! All you have to do is register (for free) every year.
If you can find an AV as good as this, tell me.
Personal notes:
1. It took out over 700 viruses on my friend's computer, who is a K@zaa lover. (you know that crap that lingers on K@zaa)
2. So far, I got 20 people to change from N0rtons to Avast, and loving it.
3. I put it on every single PC that I fix/repair, and all my computers.
