Extract the two files, then copy them to the root of your 'C' drive.
Double click on RegTI.exe, this will launch Regedit as Trusted Installer.
In Regedit, go to File > Import and select sechealth+wscsvc.reg

If you get a success message it's all good so far.

Next run Windows Powershell as administrator and run:

reg delete "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /f;Set-MpPreference -UILockdown 0;

Reboot the computer.

You're welcome :)

If you have the trial activated in Malwarebytes,

Go into Malwarebytes Settings > General tab.

Scroll down to Windows Security Center

Toggle off "Turn off Always register Malwarebytes in the Windows Security Center"

Check that no unwanted exclusions have been set in Windows Defender:

Go to -

Windows Security -> Virus & threat protection

Virus & threat protection settings -> Manage settings -> Add or remove exclusions

To remove an entry, click the drop arrow to the right of the entry and Remove.

Have you removed the malware that did this? If not, please provide Farbar Recovery Scan Tool (FRST) logs for analysis.

https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

Note: If you are using Edge or Chrome, SmartScreen may initially block the download. Click on the three dots next to the warning and select Keep => Click the Delete drop arrow => Keep anyway.

If your computer's language is not English, rename FRST64.exe to FRST64English.exe

Run the tool, leave the default settings, and press Scan.

Zip the logs, FRST.txt and Addition.txt, then upload to a cloud storage service like OneDrive, Google Drive or gofile.io

Post the share link.

It seems like Malware is involved.

Please run Malwarebytes free scan and let me know the result.

When you run SecurityHealthSetup.exe file, does Command Prompt flashes for few seconds?

Well, I can't tell for sure if that's the command prompt or not, but yes, a pop-up flashes for a second
