That's basically a tool for removing the type of crap browser hijacker/malware that can hit IE there as well. If lowered security settings and the methods at these links fail you may be having trouble with IE itself. Lately with IE 7 I suddenly can't see the images stored for posting jpgs here on the forum.
I have to suspect the newer antiphishing filter or Trend Micro's PC-cillin as the actual cause there. That will see the IE can't display page message constantly. Look over the antivirus or spyware removers you are running there to see if that is the source. But I've been hit once or twice with the about blank and a few other hijackers at times. Otherwise a removal and fresh installation of the version of IS you are running should see this corrected.
