Sure, Windows is insecure; but like all things, a chain is only as strong as it's weakest link.
Unknown to most, but the weakest link in the PC-User-Internet chain is most often the user. If you're not running IE and visiting suspicious sites full of pop-ups and ads, you'll be fine.
Using secure software (FireFox), keeping your system patched and up to date, and only browsing trusted sites will keep Windows virus free. I've ran windows for 6+ years without ever running any anti-virus software,and not ONCE did I ever get a virus.
Smart computing habits > anti-virus software.
More often then not, the folks with virus-ridden PC's are the ones browsing shady sites via IE, and thinking "Ohhhh box George Bush to Win an Xbox! Sweet, I'll try it!...*click*" (You know which ad I'm talking about! lol)
