Windows Defender Not On

Hi,



Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated.



I would suggest you to try the below methods and check:

Method 1:

I would suggest you to run virus scan to make sure the computer is free from virus.

The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove virus, spyware, and other malicious software. It works with your existing antivirus software.

• Select “Run as Administrator”.

Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

If you are getting any error codes please list those, that will be helpful in helping you.

As torre suggested, might be a good idea to do a reset or even a reinstall.

Windows 10 Windows Defender versus Microsoft Security Essentials

Hi Bryan,

Microsoft Security Essentials was upgraded to Windows defender and it was a default security software from Windows 8. You cannot have both as they are one.

Since you get this annoying popup at the startup i suggest you to disable any Microsoft Security Essentials entries in Startup tab.

• Open the Task manager. by pressing Press CTRL+Shift+ESC.
• click on Startup tab
• Right click on Microsoft Security Essentials entry and click on Disable.

Restart the computer and check if that helps.
