The Security Mentor

It's a kind of picture file for Windows, and there's lots of legitimate artwork published that way (Microsoft has published clip art in .EMF files).

You can sleep easy if you've kept your system up to date. Microsoft fixed this bug earlier this year, and Service Pack 2 is immune.
