Anti-virus deleted some essential files in windows system and caused this problem. Normally, the loss of advapi32.dll, Gdi32.dll, Kernel32.dll, or/and User32.dll will show this message. Try to copy the files from other computer to fix it.

Another case is the file c:\windows\system32\csrsrv.dll was detected by some antivirus but it is false positive. Please restore the file from virus vault or from other computer.
