anti-virus programs?!?

AVG is my choice. It is light weight and a good antivirus. There is two types of edition for AVG. One is professional and another one is personal. The personal edition is also good for antivirus. But the professional edition has the a good firewall and antispyware and email scanner, which are not present in the personal edition. Any one can download the personal edition and can upgrade it to professional edition with a very low cost than other antivirus products. The updates are also small in size. So my choice AVG.

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..
