Windows 10: Why Real-time protection of Microsoft Defender Antivirus is showing " You're using other...

Real-time protection of Microsoft Defender Antivirus is showing " You're using other antivirus providers " even when I have no other antivirus installed on my PC. I had Norton antivirus in past, but I have completely uninstalled it and also used its uninstaller 2 times. I tried almost all troubleshooting steps but still the issue persists. Please help.

Cannot turn off Real-Time Protection in Microsoft Defender Antivirus

Thanks for clarifying. No clue as to what the OP's issue is.

BTW I just tried mine (turning off RTP) to make sure it was still working on Pro....

 

Defender will only do periodic scanning, no real time protection

Hello,

This issue may happen if other security software, such as antivirus, anti-spyware, or anti-malware programs, are fully or partially installed on the computer. Windows Defender automatically turns off if you install another antivirus app.

Let us uncheck security messages for Virus Protection and Spyware, kindly follow the steps below:

• Press the Windows key + X, then select Control Panel.
• Click on Security and Maintenance.
• Click the Change Security and Maintenance Settings.
• Uncheck Spyware and unwanted software protection and Virus Protection.
• Click OK.
• Restart the device for the changes to take effect.

After the device restarted, make a full system scan using Windows defender.

To turn on real-time protection, do the steps below:

• Select the Start button, then select Settings.
• Click on Update & Security > Windows Defender.
• Turn on Real-time protection.

Update us on the results.

Regards.
