I need a good quality software to protect all PCs of an Network (like Schools, Cources, Libaries, Internetcafes etc).
It must be able to protect whole PC incl. all hard disks and partitions (incl. system partition C).
Is should restore to permitted point after each reboot.
It should be much faster than copy and disk-image. Just couple of seconds allowed.
It must be strong enaugh against all malware, viruses, users etc.
It should be able to let admin user to run windows updates or any custom software update.
