Forget the recovery disks ...
The only way to make sure you are completely virus free is to reformat and partition the hard drive ... and do a clean install of the operating system.
I used an old Win98 boot diak to format and partition mine ... and then just put in the OS CD ... and rebooted the computer.
Make sure that your system is set to boot from the CD Drive, and Windows will tqake it from there.
