Thanks for the tip Jen
Much appreciated...still a pain in the ass though and was more difficult than expected because apparently some of it was removed when I did the Hijack This, but not all of it which made the uninstaller a pain.
Anyway, for those interested, the sponsor who loaded it into their sites was MegaPornBucks, which is someone I will be deleting links from and never ever using for anything.
Thanks again Jen....
