You tried deleting your cookies and TIF, and then reseting the HP url??
Also, does it forward you to a different page when loaded, and let me guess, porn??????????, lol
Try this little trick that might work, go to your IE options, change the url to whatever you want, apply, and then change it back to about:blank , and apply, and ok, then load up IE, and see if you are redirected, if not, just go and change the url to what ever you want
