Hi ! manicmurderdoll,
I had the similar situation happen to me a while back not once but twice on two computers.
First, do you have any unwanted toolbars or unknown toolbars on your IE ?
You may want to get rid of any toolbar - Try to downloading ANTISPYWARE from Microsoft - Install it and run the update and let it scan through and delete all files shown to be removed.
Free Antispyware (Beta) - or try this new one

Post back
Cheers !
