Norton Anti virus is best

i think AVG 7.5 is good

symentac corporate edition 10.0

I am using AVG Free Edition.. why? because its free to download, and it only consume few memory.I seldom use norton anivirus, because it consume large amount of memory...specially during start-up/boot-up.It's not advisable to use norton for slow computer..If you want to use norton better upgrade ur PC..
