I use Norton System Works and upgrade every two years and keep the antivirus subscription up all years. I use this so that I also have Norton Utilities which has saved my machine several times and which I use for just general tuneups at least once a week. I've also never been knocked out by any malware of any sort; no virus, no trojan, no worm, none of that sort of thing.
