The good news is that, like most virus scares (ever notice that all of the virus warnings come from companies that happen to make their money on antivirus software? In this case, it's Trend Micro, spreading as much FUD as they can), this warning is probably overblown -- even if you are using a browser full of holes like IE, you have to wander off your beaten path of trusted sites to get in trouble. So don't click random links or follow spambait on the forums or in your email, and you'll probably be fine. But again, installing and using another browser is so easy (and will help you so much in the long run) that you might as well give up IE anyway.
Thanks to everybody who sent this in! And yes, I used the old login screen for this post's picture. But don't you kind of miss it?
