Sacked off goin to PC World & done the norton scan & found W32 Spybot Worm virus & Quarantined it as it can't be repaired or it seems can't as norton anti-virus surgests be deleted either, as for "DELETING THE VALUE FROM THE REGISTRY" as far as I can see there is no zero byte files in my startup folder & having never had to remove a virus before Nortons instructions are making me twitch in a nervous " what if I remove a legitimate tftp file " type way ..Please if theres any "lets say for example step by step advice" you could offer me to back up Nortons instructions..
