I would also like to note that either this, or one of the infections it downloads, appears to have the ability to root itself inside random executables on your hard drive. I am already to the point of reinstalling Windows on another HD, and when I attached the infected drive to pull off what files I could, it then infected my new build of XPSP3. It was just a random file (Foxit reader 3.0 installer) that I had stored, and when running it, it did its magic all over again.
