There are some pretty good free anti-virus softwares out there. I'd say by this chart, AVG and Avast are the best free ones.

These all basically got the same ratings.
The question is, is paid really worth it vs a free anti virus? I've been using McAfee but my sub is up and I don't know if I want to pay for another year (and another after that, etc). They are offering me a renewal for $39.99.
What do ya'll use?
