The best anti-virus at the moment

Have been using Avast for 2 years now with no problem..

kaspersky is the best

my vote goes to NOD32 !!

Norton FTW! I use the Internet security package . Cant beat it .

I agree with UKMAN that AVG Free edition coupled with spybot and registry mechanic and ad-aware do an excellent job.

Spybot is free to download www.spybot.com and ad-aware also has a free version .

I think NOD32, because it's easy on your computer, it's fast, clean and effective. And those are pretty much the things i value!

I have been using Avast (along with spyware doctor and registry mechanic and ad-aware) and i must say is great!!

NOD 32 all the way

AVG antivirus I'd say: http://www.freeapps.co.uk/apps/avg
Or ubuntu linux: http://www.ubuntu.org - then you don't have to worry about viruses :)

Never used anything other than NAV.
