Sounds like you caught a nasty case of browser help object. BHO's are what allow 3rd party addons like google toolbars etc to work but can be misused or just (as in this case probably) badly programmed. Get MS anti spyware off the site and look in advanced tools, there is a section to list BHO's if you select them one at a time the right hand window will tell you if microsoft 'knows' them. Delete all that it doesnt. If you been surfing porn with IE dont be surprised if you have got 10-15 unknowns. Various less scrupulous sites use them for tracking since unlike cookies they cant be turned off or removed easily. Do a spyware scan and delete anyway if you dont already have microsoft spyware installed.
