To fix this, you can try the following troubleshooting solutions and see if any of them works.
Solution #1 – Disable any third party antivirus or anti malware
Windows Defender problem can occur when you install other antivirus or anti malware programs on your PC. Even though Windows Defender stops itself from getting any signal from other antivirus, there just some times when a problem can occur because of some internal error, you can disable it to see if the problem still persist or not. And if the problem gets fixed after doing that, then you may have to reinstall the third party antivirus.
Solution #2 – Turn on the Windows Defender service
Based on the error message, the Windows Defender service has been stopped, so of course, you have to turn it on by using the Windows Services Manager. How? Follow these steps.
Step 1: Type in services.msc in the search box of your Taskbar and then tap Enter to open it.
Step 2: After that, check the status of the services below:
- Windows Defender Advanced Threat Protection Service
- Windows Defender Antivirus Network Inspection Service
- Windows Defender Antivirus Service
- Windows Defender Security Center Service
As you can see, the Startup type for the Services above should all be set to Automatic and they should be started as well. If it’s not, you have to turn that Service on.
