Recommendations on antivirus software?

nod 32 is best but expensive

Don't use antivirus, it slows down your pc. Instead, just den't get a virus.

Avast

AVG + Comodo Firewall, you can't go wrong with that :)

The NoScript addon is your best line of defense.
From what I've been told, Anti-Viruses only detect 40% of viruses / spywares. Basically I think they are pretty worthless. Just be careful when you browse.

AVG :P

MSE + Malwarebytes + Adblock

Avast! latest + MS Windows Defender + smart use of Internet!

MS Essential

NOD

ZoneAlarm Antivirus+Firewall by CheckPoint worked great for me but Avast is working well too... Anyways I'd always choose NIS full version over free software

I started out with Trend, then Avast, now MS Security Essentials. Whichever one you choose, don't use more than one. It can cause all sorts of conflicts with your machine and well, just don't.
