You should download a copy of Malwarebytes Antimalware. Install, update, and run it. Reboot your PC into Safe Mode with Neworking. Rerun Superantispyware and Malwarebytes. Reboot into Windows and see if its running better.
If not, you will need to run a Windows repair/replace your system files. You will need your Windows CD to do this. You can also try running 'sfc /scannow' from the command prompt (Click Start>Accessories>Right-click on Command Prompt and choose run as administrator).
