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.
