Yep I think you probably know by now AX, I agree 110% with that. Nod32 has consistently performed in tests for over half a decade now, and has never failed to achieve 100% in Virus Bulletin and AV Comparatives tests (the industry standard for virus scanner checking).
It can even in most cases, detect new virus's that arnt yet known thanks to it's industry leading heuristic technology, Threatsense.
The other major winning aspect for Nod over all other Antivirus software, which in itself is worth having it for, is the tiny memory footprint it uses and non-intrusive way in which it works. There is nothing worse then having antivirus software that uses a mass of memory and literally rapes you're CPU for no reason, even moreso when they are actually pretty lame at defending you in the event of a virus, like Norton etc...
I am now using ESET Smart Security and have been for a good 6 months or more. It includes Nod32 but also a pretty strong and "quiet but clever" firewall, adware and spyware filters, and spam protection. Perfect security package imho.
