What is the best antivirus program of 2007-08?

I'm trying to look online for the best antivirus program of 2007-08, and I don't know what to do because every website I go to has different top tens, and I don't know which one to trust. Up until now I've been using Trend Micro, so I don't know, any advice?

What is the best antivirus program of 2007-08?norton antivirus

AVG beyond any shadow of doubt and it's free.

I had norton and got a virus, i had Mcafee throug aOL and uninstalled it.

Get AVG
from a consumer reports of last year i read that for Viruses (not spyware) BitDefender Was The Best
I don't know the best, but i know the worst. And they are:

~Norton

~McAfee

~ZoneAlarm

Why worst? one of the many reason's is, they slow your computer down (they really do), it's hard to get rid of them (they try to stick in your machine even if you do uninstall them), and last but not least, almost all hackers/viruses know that one of those antivirus software is running in your computer. They know how to get away with it. And even if you always update your virus definitions, it would take them a couple of days to find out about these new viruses. And before they make a cure for it, it already has infected your computer. You might be able to clean/remove it later, but the damage has been done.
