so..heres the deal. today i was in study hall, and was not reallly studying, while on the computer (e.g, on facebook). Then, before i knew it, my mouse started to move and it closed all of my programs and i had no control. Somehow, the librarians in the library have a program that can view and control each computer in the library from their desktop. How can i block this from viewing my computer? or how can i turn it back? thanks! (links are appreciated)
