I have an unknown software that resets the computer to the same point after i turn it off. It is set so nothing that was installed after that point in time remains on the computer whether it is a virus or a game. What are some famous softwares that do this? I know schools use this kind of software. I have AVG antivirus and I heard AVG has some option to control this sort of stuff. I think an example of this kind of software is Deep Freeze but I don't think I have that one specifically.
Anyways, how can I look for the one I have? maybe someone can tell me what to do in order to disable this option on AVG?
