Well to add to the free AV and Firewalls, Comodo, one the leading SSL company's, has released a full on security suite, for free. These are much better than any of the other free options (in my opinion), and even most of the paid. I have removed Norton 2007 from 5 PC's and installed this already, and its actually on par with Norton, but without the cost. The firewall and anti virus, have this neet little feature, if something seems suspicious to the programs, it will ask if you want to upload the file to there server so there techs can test it and check the code, and they will then release an update if the file is to be trusted or not to everyone who uses the product. And unlike some other firewalls, that have failed at the system, this ones learning system is actually very intelligent. It will make rules based on how you actually use programs that access the net, and not just based off pops asking if you want to allow or deny.
All the security you will need!
