Everyone will agree Avas,nod32 and AVG are the best choices. They are all pretty the same just diffrent name + interface. ;O I recommand Avast, since it's simpley simpley to use + you have everything you need.
Avira and Nod32 seems to be by far the best at detecting unknown malware (with AVG at the other end of the spectrum), while the difference is a lot smaller for known malware.
nod32 is way over those crap progrems...
avg is only good with his anti spyware.
nod32 can track every virus who mutant
every major site declare that nod32 is the best out there and it allmost doesnt take resource on pc
