+1 to those above. I'll add Avira (except for the splash page that prompts you to pay for the full version). I am a big fan of Comodo for firewalls/AV...but I'm an even bigger fan of Online Armor. It will do it all...and just a week or so ago they gave the full version away for free at giveawayoftheday.com. Both Comodo and Online Armor take something as complex as a firewall, and make it easy to use for those folks who don't normally deal with that stuff. Online Armor is highly rated..and to be honest, I'd pay full price for the full version. Comodo was great too, but it wouldn't work with PlayOn, and I got tired of waiting for an update to fix it. Oh yeah..if you need to clean malware, superantispyware.com has fixed everything I've thrown at it. I can't say the same for Spybot and the like.
