I'm only concerned as I'd recently had a falling out with several internet users who have periodically harassed me and friends. I looked to my webcam, a 'Logitech' of sorts that plugs in and all. It wasn't on my computer monitor, because I'm already skeptical as it is, but was facing my keyboard and hands. The green light was on, signifying that the camera had been activated and was in use. I didn't do this, and there was absolutely no program on that I can think responsible. I did have it face myself at one point for a short period before unplugging it, which was probably a big mistake on my end if something malicious is going on. But I did, and now I am frightful that it could be an issue. Should I really be worried?
