How did you "go back to version 7"??
Do NOT use System Restore to remove/uninstall IE8 or any other application!!
How to uninstall or remove Internet Explorer 8

What anti-virus application or security suite is installed and is your
subscription current? What anti-spyware applications (other than Defender)?
What third-party firewall (if any)? Were any of these applications running
in the background when you installed and/or "went back to" IE7?
Has a(another) Norton or McAfee application ever been installed on this
machine (e.g., a free-trial version that came preinstalled when you bought
it)?
