I'm Building a 'Share your computer' kinda app.
The user will login with his info, then after 30 be not able to use the computer.
The problem is that the user sometimes loads a usb drive then kills my program with a simple kill process call.

I want to:
#1 make the program run silent in the background.
#2 make the program not able to be closed by Alt-Ctrl-Del, or Process kill
