What is the best antvirus?

according to me norton is really good and its infact the best one

I use AVG-FREE here at work on our network and also on all my other 7 computers at home. I have every operating system in play. With Norton my Windows 95 had conflicts. With McCafee my Windows ME had conflicts. With some of the other antivirus programs listed here I had conflicts in windows 98 and 2000. So, I installed AVG-free on all those computers and have been using this antivirus for 3 years with zero conflicts on windows, 95,95,me,2000 and xp. So AVG gets my vote and it is FREE!

i reckon using Trend Micro PC-cillin anti-virus. It's really good. I have been using it for 2 years now. It's the best for PC.

i never try but i read some site who say that AntivirusKit is the best after it's Kaspersky but he uses a lot of RAM and he is slow NOD32 is almost like kaspersky but he is the antivirus that takes the less RAM in your pc,so nod32 is very very good...a lot of test prove that

McAfee the best..

Im using Norton Anti-Virus and works fine with me.

I think KIS is the best!
