A Google search for this message turns up many pages of hits all relating to Adobe Flash Player and going back 5 or more years. Some users even report it locking up their computer. I obviously did not read all the hits but the commonly suggested fix is to be sure Flash Player and any other installed Adobe products are up to date or to remove Flash Player.
