Running the recover disk does not kill off the virus, (Virus's). Windows system restore must be turned off first. If you left it on the virus will load when windows starts up. Some virus sit in memory. Best to shut down the system. Pull the power cord from the power supply & pull your memory. Wait a few seconds & re-incert the memory, plug the power cord back in, than run your recovery disk. After you run the disks update windows. Re-boot as needed.
