Download SecurityHealthSetup:
Right click on securityhealthsetup_e16941e14861a6d24750ecdf05c548189b33182a.exe and run as administrator. You should see a couple of command windows flash.
The Windows Security UI should work straight away. If not, restart the computer and give the system a few minutes to initialize before checking.
If that doesn't work, please run Farbar Recovery Scan Tool (FRST) and share your logs.
