Avast, Avg, and clamwin are most known. Don't forget spyware protection though. Very important these days. Best freeware program for that is Spybot Search and Destroy. Microsoft also offers a free anti spyware program called Windows Defender.

i don't really trust in free antiviruses cos i use paid one (nod32), but you can get free anti-spyware at http://www.2-spyware.com/review-spybot-s...
They're many free Aunti Virus protections, but those are not protective compared to the costly ones. You will still get viruses and spyware with these free programs. Some people say Free Anti Virus protections are as great as the costly ones, which is totally wrong. McAfee has found more than 90 viruses on my computer when I used to use the free ones, which never detected the viruses.

I would say pay for McAfee. Norton is terrible in my opinion.
AVG. You can go to this link http://free.grisoft.com/ With best regard.
