Please do the following and upload the respective logs.

Step 1:

Download Farbar Recovery Scan Tool (FRST64.exe)

• Run FRST64.exe and click "Scan".
• Upload the two logs, namely, FRST.txt and Addition.txt, to your OneDrive and share the link here.

Step 2:

Download defender_diag.bat. Right-click on the file, click Properties, Unblock, and OK. Run the batch file as administrator.

The Batch file queries Defender-related settings/Policies and outputs the results to a log file. Upload this log to your OneDrive and share the link here.

Note: Before uploading the log to your OneDrive, edit the defender.log file and remove your Email ID if found.

Hi, shahnawaz. I'm sorry to hear you're having this problem, and I hope I can assist you to find a satisfactory solution.

We can check the file system and if it doesn't work, you can restore a previous version of the system.

Check File System

Type CMD in the start search bar

right click on the command prompt program and select run as administrator

run this command

Dism /Online /Cleanup-Image /ScanHealth

When finished, do this now

Dism /Online /Cleanup-Image /RestoreHealth

Then use this command

sfc /scannow

Restart and verify if works.

You can try restoring your computer to a previous state when Windows Security was working fine. Search for "System Restore" in the Start menu and follow the on-screen instructions to restore your system.
