There are probably thousands of links offering instructions on removing the "Google Redirect" malware. Have you tried any of those instructions?
The BEST solution is to restore the system from backups. Assuming you don't have those, the next best solution is to copy important data elsewhere and rebuild the system from scratch. There's really no way for a non-expert to be sure that everything's removed after a malware repair.
If you're going to rebuild a system, be sure you've gotten the license Keys for any installed software, that you've copied your Internet Favorites and any email stored on the PC, that you've got any email account and web site passwords recorded, that' you've got OS and program installations disks, and you've got a list of devices/drivers installed on your PC.
After you've got a clean system, I strongly recommend making periodic system image backups so you can quickly restore it to a clean state. Removing malware is a huge time waster and malware is getting smarter and tougher to remove.
