anti-virus

Hey /comp/,
     I jut got a new laptop and I need a free antivirus program for it. What should I get? I've heard about this nod32 but it's only a 30 day trial and all the torents/cracks/etc. are questionable. Any advice?

ok, i'm using nod32, and i ran past my 30 day trial
All it means is
"Lol, delete it, or else you suck D:"
But it works fine
