Every month or two the XP auto update thingy downloads a Microsoft
Malicious Product Removal Tool, but after the update is completed I don't
see any evidence of anything happening.  Does it require any user input? 
It doesn't show up on the Programs menu anywhere.  Does it just run once in
the background, do its thing, and go away?
