Install WinPatrol to prevent home page hijacking
After you remove the hijacker please do yourself a favor and go to http://www.winpatrol.com and download the latest version (free) and install it. I have used it for over a year and my home page never gets hijacked by anything because WinPatrol will let you know something wants to change your home page to... and you just click on No and this tiny little program will protect your computer from this ever happening. I love this program and would not be on the net without it.
