Put tape over your webcam

Yeah, I've been doing this with all my laptops since the first one as well. It's not just that it can be 'hacked', different websites actually try to activate your camera and microphone on a daily basis (you should get the internal microphone of the laptop disabled while you're at it as well).

I don't get it why it's in there in the first place. If you want to input a video separate webcams exist for that purpose to plug into the computer.
