Firewall and AntiVirus for Windows

I mostly use mac, so it can be easy to forget about firewalls and antivirus software. Anyhow, I reloaded my windows based laptop and started searching for free software. Here's what I found:

For free firewalls, the best in early 2010 are:
1) Comodo
2) Online Armor
3) ZoneAlarm

For free antivirus, the best in early 2010 are:
1) Avast
2) Avira
3) AVG

The best paid antivirus programs for windows are:
1) BitDefender
2) Kapersky
3) Norton

For Mac's, the best antivirus programs are:
1) Norton
2) VirusBarrier X5
3) ClamXav <-- free


My findings are based off of reviews from CNET, PCMag, PCWorld.
