Every time I hit the camera import button in iMovie, I get a file listed that's an ex-Big Brother member from the UK in a compromising position (or two). I don't have this movie on any storage devices connected to my computer and hadn't seen it until it appeared by itself in iMovie. This movie selects itself by putting a tick in the little box under it. Is there 1) a way of finding where this movie lives or gets itself listed? I've deleted all my projects but it still appears; and 2) is this some kind of a Mac trojan horse or virus that's installed itself? I haven't been to any dodgy sites or downloaded anything stupidly. There's nothing in preferences to say where a file can be pulled from or anything like that. Any advice welcome!
