The Windows Defender Advanced Threat Protection Service service terminated unexpectedly.

Hi Vincenzo,

Are you seeing multiple error events related to the Windows Defender Advanced Threat Protection service (Sense)? You can check Control Panel → View Reliability History to see if the Windows Defender Advanced Threat Protection service is crashing.

I had the same issue in one of my systems. Eventually, I had to delete the Sense service. MSSense.exe Crashes: Windows Defender Advanced Threat Protection Service Executable. This may not be the best advice, but that's the only one that worked. Note that this service doesn't exist on Windows Home editions.

Hello again, I'm not using any third-party anti virus. Also I scanned using the offline scanner like you told me. But the problem still persist. Beside from that there is also shown warning here.

Dear VincenzoCassano,have you installed any third-party antivirus software previously?

If so, I suggest you uninstall them completely for testing;

Try performing an offline Defender scan for threats;

Go to Windows security and click on Virus and threat protection;

Click Scan Options;

Check "Microsoft Defender Offline Scan" and click Scan Now.

Your PC will restart and take approximately 15 minutes;

After the end of the process, restart the PC and check if the problem persists;

See you soon!
