The Security Mentor

Microsoft just released a patch for the critically dangerous problem that could allow a bad guy to take over your machine by getting you ot look at an image file, or in some cases even if you never look at it.

Pick Windows Update from the Start menu, or you can install the Official patch for the WMF vulnerability from Firefox by following the link and looking for the patch that matches your version of Windows.

I recommend uninstalling the unofficial patch. I recommend doing that first, and not leaving any time between that uninstall and running Windows Update. Keep the unofficial patch around just in case. (It looks like they do the same job in slightly different ways. I'm recommending the official Microsoft patch over the unofficial patch because Microsoft can afford to do more testing than an individual can, and because you have a better chance of getting support if you haven't installed unapproved parts in the guts of your Windows installation.
