Windows 10: Can't open windows defender

When I open it there only is a window with the logo in it. I repaired it and reinitiated it but doesn't work. I did all the powershell and cmd commands I could but still doesn't work and I heard that you need to download securityhealth but I can't find the file anywhere and the only 3 I found don't work. I tried switching it off and back on same problem occurs and since we can't really manually uninstall it and download it again I am stuck.

how to reinstall windows defender?

The system is infected by miners and other malware, which have deleted your Defender executables completely. A repair installation is suggested.

Before that, please do the following:

• Download FixList.txt
  

• Save Fixlist.txt in the same folder where EnglishFRST64.exe is.
  
• Close all program windows.
  

• Launch the Farbar Scanner tool and click "Fix".
  
• Upload the output log file (FixLog.txt) to your OneDrive.
  

Once done, repair Windows 10. See How to perform an In-place Upgrade with Windows 10 Step-by-Step Guide - Microsoft Community:
