:( That's really nasty. Can you use a self-help guide?
If yes, please try the guide in http://www.geekstogo.com/forum/How-to-fix-Google-Redirects-t267407.html
You will need to download few more tools in addition to the above tools in my previous posts.
If the guide will not help or you want your system analyze, kindly go to http://hjt-data.trendmicro.com/hjt/analyzethis/index.php
Choose one of the malware removal forum in the list and follow the instruction on how to post a log.
