Indeed. I don't know how many people use spybot - it's a nifty little utility. It's got me wondering though - when you opt to perform a full system scan, the program literally searches known viruses, worms, trojans, etc by name. You get a window with the names of the ick it's looking for at the bottom. So, it'll say something like 89% of scan complete....Zlob.download.net (just for example).
I have a 13 year old boy who downloads any free game he can find so I've had my fair share of nasties on my PC. Spybot will only remove some automatically while others can only be deleted by going into the registry manually to delete it, clearing caches, cleaning the registry, and sometimes having to repeat the process a few times over to remove all the registry keys associated with a certain virus.
Just thinking aloud, really, and wondering how spybot's files appear on a hard drive. Hmmm.
