Spyware, viral cleanup disabling system restore
Sorry, but to get into the guts of what I found in the wake of the WMF exploit, I did leave out another important step in the cleanup process. IF you are trying to clean up an infested machine one of the first real goals has to be disabling system restore. (start, (settings,) control panel, system, system restore, and use the checkbox on that sheet, then ok to confirm.) This was one of the first things I did after infection to start the process of cleaning up. Windows uses system restore to keep copies of vital windows files. Unfortunately they can be viral/trojaned files as well.
