I'm sure we've covered this before but what do you guys find to be the best antivirus setup? I'm looking for something with limited system resources impact. Aka something that will not slow my PC down much if at all. I just had an episode with some crap that I have no idea where it came from. My usual spyware programs and windows firewall did jack to protect me and had a heck of a time working it out. I luckily downloaded a program or two that helped before the virus took over my browser and blocked all but its websites. All this programs will probably work if I have trouble again but I'd rather one set of programs that are meant to work together.
