Hello,
If you ran SFC several times, there may possibly be a problem with the SFC. That said, you can run DISM:
- Run Command Prompt as administrator.
- Type "DISM /Online /Cleanup-Image /RestoreHealth" and press enter.
- Be patient.
- After it finishes, restart your computer and run SFC again to see if the corruption comes back again.
The only other option would be to reset your system:
- Press Windows Key and type Settings. Press Enter.
- Select Update and Security.
- Choose Recovery.
- Click Get Started under Reset this PC.
- Choose Remove everything.
- Then, Remove files and clean the drive.
- Choose Next, then Reset.
This will take a significant amount of time to reset your computer to factory settings. Note that ALL files will be deleted, so hopefully, you have a backup of your important files. I would not recommend completing a backup now, as your files may be infected. That said, the infection may return after the reset if any of your files are infected.
