People, ENOUGH of the replies saying "Don't click the popup" or anything like that. THIS HAS NOTHING TO DO WITH CLICKING AN AD. Sorry for the caps but maybe, just maybe, it'll help get through to some people that it's an automatic redirect, far more dangerous.
Think the OP heard enough of "Don't do this, you should have done that" - He knows now, he is primarily using this to inform others to beware of these pop-ups. He is trying to help people, like himself, who doesn't always know what to do when a pop up.. pops up.. So quit the preaching, and give the man some kudos for not just passing it by, but actually letting people know and helping.
