Good free antivirus software?hp

AVG free edition

Good free antivirus software?mcaffee

there is no such animal. My sister had that VGA and when she finally took it into a shop, it had over 400 viruses and adwares! Believe me, the 40 bucks for norton is well worth it.
do not use norton, honestly it is so annoying, it keeps asking if it can do stuff every 10 seconds, i had to uninstall it.

use AVG free or if you want to buy it use normal AVG
use AVG, its free
if you have comcast internet you can use mcaffee for free. Lavasoft Ad-Aware is free, and it's really good to for removing adware.

I've also used AVG, but it seems to quit out on me and stop detecting anything. I think it's pretty crappy.
Spybot is good also.

Use Avast AND a program called CCleaner

That should take care of your system really well. I've been running 'em for almost two years and never had one single problem.
AVG and Avast are two common downloadable anti-virus programs.
Avg free with spybot search and destroy make a good free combination.
Avast!

I just installed AVG today after refusing to pay Norton's rediculous annual renewal fee.
