I searched but didn't see a quick answer on this...can either of these spyware programs prevent the stuff from being put on in the first place? Sort of like an antivirus that runs in the background. I do some tech support for a local library and it seems more and more lately the public users are finding every site under the sun that loads adult and casino and god knows what else crap onto it. As it is now, I routinely have to go and uninstall whatever crap they've put on, and haven't found a reliable way to keep people from doing it. They're running a mix of NT and win98, and I've pumped up the security settings, etc., but there still seems to be these ones that get through. Thanks!
