when I arrived at her house I was surprised to see there was no AV software and only the XP firewall! (and this PC was supplied from her IT dept!!). Ran adware & Spybot 3 or 4 times each, they found shedloads of c**p, every time I ran tham they found something differant, but eventually the pop-ups stopped. Uninstalled a corrupt copy of Nero, and hey-presto CPU back to normal!. Have installed NIS 2003 and a fresh copy of Nero and all is well.
Thanks for your import peeps, as always it is much appreciated
So long and thanks for the fish!
