Have you tryed going to the Windows forums. to ask about IE 7
also if you are looking up coppyright files with IE, somethig may have come
back at you, like a little worm, Give your system a good scan with more than
one program
Check your system using any of these programs (I reckon using all of them):
http://www.lavasoftusa.com/software/adaware/(free)

http://www.grisoft.com(good free AVG)

http://www.ewido.com(>>now called AVG Anti Spyware<< free 30 day trial -the best in my opinion)

http://www.ccleaner.com/download/(free)

Spybot - Search & Destroy (FREE)

If you can't get rid of it go here and get some free computer help:
