You shouldn't have clicked it in the first place. Titles may be tempting, but look at the file size. It might give you a clue.
If everyone used that logic, the portal would be full of spam with no views. With the new view, the flash could just auto play, so it's a problem with Newground safety, not the user.
If this happened to me, I would first try to do a system restore, then try to find the file myself, and if all else fails, back up all my shit and do a clean OS install.
