go for NOD 32…its great
+1 for NOD32
another vote for the Nod 32
use it with zone alarm firewall..
Antivir is the best
+1 for NOD32 . its very lite compared to others n extremely effective . 
BTW wats the price for original copy of NOD32 ?
ya sure… 1gb for a anti-virus is definitely not resource hungry!!! 
NOD32 anyday ..
Paid: Nod32, Kaspersky
Free: Antivir, AVG
i am using now trend micro pccillin..and it works fine..it can really recognize different viruses, spywares and malwares..try it!!approve to be the best 100%..
$30 i think, NOD32 + ZA = best combo
AVG Free + Adaware 2007 keeps both my systems fine…
Edit : so many nod32 and KAV fans!..
Me too using avg since last 4-5 years…no probs at all…+ using avg antispyware/Adaware SE personal/S&D spyware…works fine…not even a single virus infection all these years.
+2 for NOD32
PROBLEM WITH KASPERSKY IS
IT BLOCKED MY REDIFFMAIL,RESOUCE HOG,AND INTERFERING WITH SOFTWARE INSTALLATION
AVG =NO
AWAST=NO
KSAPERESKY=RISKY for system (resource hungry- as i hear)
ZA=NO
NOD32=EXCELLENT so far and very low resource requires (don’t know exactly how but no problem with so far in last 7 months)
GO FOR NOD32
