You might want to try running RKill to stop any malicious processes that may be blocking anti-malware programs.
Do NOT reboot after running RKill, proceed directly to running MSRT and any scanners you wish to use. Once RKill has been run, R Click on the stand-alone version of MSRT & select "Run as administrator" to see if this will help it to run.

If the registry keys are indeed missing & you cannot access a restore point from earlier, you may wish to consider looking at this tutorial. Options also included are Reset & Refresh.As RKill only terminates a program's running process, and does not delete any files, after running it you should not reboot your computer as any malware processes that are configured to start automatically will just be started again. Instead, after running RKill you should immediately scan your computer using some sort of anti-malware or anti-virus program so that the infections can be properly removed.
