Is my computer haunted?
curious if anyone here can advise me how to test if my recently purchased macbook is infested with some sort of surveillance muck? and if so, how to rid myself of it? every so often while on line a blank box square appears on my screen, as if snapping a screen grab. also, when i write, the text jumps around. i know i'm paranoid but...isn't paranoid the new "of course people are watching you!"
