I am freaked. Spooked. I have a trusty old Mac book. I have no 'chat' applications currently open on my laptap; no skype, no facetime, no photobooth. BUT my little green webcam light on is on.

And it's unnerving me. Is this a hacker thing? I feel like I vaguely remember reading something like that; people would hack into your computer and switch on your camera. Is this a virus?

What should I do?? help me turn this camera off!
