Hi, I have Norton installed [have had it renewed each year for 4 years] I've never had this before, but a message keeps coming onto my screen now and then from Norton saying 'HIGH DISK USAGE BY WINDOWS MODULES INSTALLER' I haven't got a clue what it means, can anyone explain, I am not very computer savvy so please explain in 'simple terms' it is starting to worry me a tad, many thanks, Joddington
