These are public computers? Well then first off... there would virtually be no problems if you and home users alike would put some policies in place. Think about it... millions of $$$ in AV and Firewall software yet everyone goes online and does mostly everything else useing full administrative rights and all the default settings right from install. Also the thing about school computers... if your taking care of them then isn't it YOUR job to update?

First off... these people (and malware) should not have ability to edit the registry or make any other major changes to these systems for that matter, none of these computers should automaticly execute anything from removable storage, all ftp tftp instant-messaging & gaming related connections should be dropped... this really pisses people off the most.

I don't even have the clipboard enabled no cut and pasting for you, *******!
