Massively nasty windows security flaw, beware

UPDATE: Someone just tried to send me a virus masked as a "Greeting Card." There was a link in the email that said to click it to see my greeting card - the link then pretended it was a link to an image - but if you hovered your mouse over the link without clicking it you see that the link isn't to an image at all, it's to a program. And if you click, you download and run the program. This has to be a virus - anything pretending to be an image (.gif) but really being a program (.gif.exe) is a virus. Just be careful, I almost fell for the thing. If you click the image above you can see what I received, and see the fake link. JOHN

Apparently a particularly nasty Windows security flaw has been uncovered, and this one can screw up your computer by simply visiting a Web page or looking at a picture in your Microsoft Outlook email preview pane. Nice.

Anyway, you can read more about it here.

The Washington Post's blog is linking to an unofficial patch that, while you should use at your own risk, the Post says top security experts are recommending the patch since Microsoft may not have a patch for days. You can find the patch here. Again, use it at your own risk (I did).
