Thanks for the advice Jephree.I created a new account and assigned it to admin,then opened I.E and all was ok.I then followed your link to transfer all details except those mentioned on that page and everything is back to normal so far(all apart from having windows welcoming me to all apparently"new"tasks and giving me helpful hints etc)i can put up with that though.
I hope this helps others with the same issues as well ,as i know from other forums that i am not alone on this problem.Microsoft/windows help pages do not offer much help to the novice as i have been there for the last week or so trying to search and find a fix that someone like Jephree can sort out in less than 24 hours since this was posted.For instance try finding out how to delete the old account that you no longer need in windows or microsoft help pages!!!
Regards and till next time,Johnojones.
P.S. Never open Zips from unknown origin even after a Norton scan!!!
