Trend Micro is excellent as well, it's just not as well known

NOD32, Norton Antivirus 2009, Norton Internet Security 2009 are my favorites. Low on system resources and a tiny footprint.

And one can purchase Norton Antivirus for $0.00 after rebate, or $20.00 after rebate for Internet Security from Fry's (at least last time I checked).

antivirus in general is completely useless if your D has any common sense at all. i've never used it once, and no viruses ever.

Neither do I, but I wouldn't call it "common sense." Plus, on a large university network, it's probably best to have an antivirus.

A lot of college networks won't let you in if you don't have an antivirus

While common sense is the best defense against viruses, it'd be quite reckless to go without it. You never know when you might get unlucky, or there's some odd security hole that gets exploited. Although anti-virus may have it's faults too, it's a good second line of defense.

However, I wouldn't be paying for one. I've been using Avast and AVG free edition (both of which are free for personal use) for serveral years, and they've been reliably keeping my computers running virus free and at tip-top performance; that is, just as fast as they were when they were brand new.

Oh yeah, don't forget about anti-spyware. They're not quite viruses but pose just as much of a problem. If computer viruses are comparable to getting a cold, spyware/adware is comparable to having annoying friends that seriously disrupt your life. Again, I recommend some free tools: AdAware and Spybot.
