for free anti-virus I recommend avast free 5.0. Its what i used before upgrading to the pro. the free version is just as good. the only thing missing from the free is firewall, which you can download several excellent free firewalls( i recommend and use pc tools firewall, ashampoo, online armour, and zone alarm are all excellent. stay away from outpost, its a headache), the anti spam blocker(which most emails already have), script shield, and process virtualization. out of all of those, only the sandbox(process virtualization) is worth paying for. But as long as I had the free version i never once got a virus or malware. They have an excellent web shield(better than aviras i think) that stops anything bad before it can connect or load. If you have an older single core computer, be sure you disable some options in the file system shield, like scan documents when opening and writing, or it will really slow down your system. The number and quality of the other shields are good enough(if you stick with the default settings) that you dont need the file system shield to scan every file everytime you open it or execute it. Avira is a good second choice, however I did get some malware once that avira did not catch, so i switched to avast. Avasts user interface is ten times better looking than aviras simple and ugly one. Another good second choice is AdAware free, as it contains not only anti virus engine, but protects you from malware and spyware as well. I know several IT guys who use only AdAware and spybot and no AV program and swear by it. as long as you are smart about where you surf. I would still recommend using Avast free. it cant hurt and can only help you.
