i think kaspesky is the best.
i'm using KIS2011 and works fine.

Nod32 ...heard it's programmed in assembler --> fast

i like using microsoft ant-virus, haven't had any problems with it.
i always test any new software within a virtual machine first.

NOD32 gets my vote...light on the system and does a great job..

kaspersky 2011 total security is best antivirus (:

Going with Nod32, cant go wrong with it.

I use Avast full edition about 1 year and is pretty good.

Voted for Nod32 and kaspersky, Eset nod32 isn't the best in 0-day virus detection tests, but when we speak about speed nod32 is the winner

avast is my favourite antivirus

I use Norton 2010
