going to get my kid a laptop. I want it locked down so he can't install shit on it and get viruses and shit I'll have to clean up later. recommendations for "sandbox" kind of software that'll let him fuck around with IE/firefox, but will undo anything that's installed/allowed when he's done? I thought vmware had something that kind of did this but I can't find what i was remembering. how about something like this? http://www.sandboxie.com/ or any other suggestions?
