OK, it sounds like you're not running the system file checker scan from an elevated command prompt.
Click the Start button > type cmd
in the start search box > right
-click the cmd icon in the upper panel > select Run as administrator > click Yes at user account control prompt.
You should now see a black screen with white letters called Administrator.
There should be a flashing cursor immediately after C:\Windows\system32>_
Just type in sfc /scannow (there is a space between sfc and /scannow) and click Enter. The system file checker scan should begin. It could take a while so be patient. As I said earlier, if problems are found, run the scan 3 times and make sure you restart the computer after each scan.
And follow the excellent suggestion by mitchell65 to run the WDO scan. You need to create the boot disk on a machine that is not infected or it may not run properly.
