Some of you may be running Windows. If that’s the case you’ll want to install this update right away if you’re using Internet Explorer: Download details: Security Update for Windows XP (KB912919).

Here’s the thing: Internet Explorer is a security nightmare. If you are running Internet Explorer it looks at files with any sort of graphical extension and then ignores the fact that it is a graphical extension with a specific name and then tries to render it how it thinks it should. Thus, if someone runs the Windows Media File exploit on an image ending with GIF (a different graphics format) Internet Explorer ignores that it can’t render the image as a GIF file and runs the Windows Media File executing the attack!

Please, after installing that patch, install Firefox or Opera.
