If you cannot search from the address bar and overture.com or igetnet takes over your address bar, download the removal tool from:
http://www.getmikee.com/Downloads.htm
simply save it to your desktop, doubleclick it, click yes.
After doing this, you have your address bar back, like it's suppose to be!
You can delete the file you downloaded. You don't need it anymore.
