Recently a couple of users on my network were caught with inapropriate materials on their computers. Where there is one there are probably others, so we began digging through more user's machines and found even more. Go figure.

I am looking for a utility or something that I can use to scan my user's computers remotely for images and video. If it can be automated, then that is even better.

Has anyone else had to deal with this kind of problem before?
