It's never impossible to terminate the self-defence of a program. The best self-defence of ANY program I have ever seen or come across so far was Deep-Freeze. What it did is tracked everything the user did in their session and undid any changes on the next startup. The owner would set up the enviroment as they wanted it to be used and then installed the program and at first inspection the computer was fully open but you could fully and completely delete every file and folder on your system drive or any other drive not marked as protected and it would all be back at next startup. A friend of mine managed to get my old high schools install file (with embedded password) and then installed it on my PC when I went to get my dinner and it took me almost two weeks of constant fiddling to remove it without formating (which they also say it protects against but didn't wanna test it out ). Anyone else here every seen or used Deep-Freeze?
