Every time I attempt to connect to the internet I get a dialogue box that asks do you want to allow this programme to make changes? The publisher is Mozilla, and it also tells me that it relates to Firefox software updater. Never had this until about two hours ago! Also seemed to relate to a crash of McAffee, which happened at around the same time.. Don't know much about computers, but what I do know is that this has only just started... Help...??? == This happened == Every time Firefox opened == About two hours ago.
