Windows 10: Windows Security Essentials and Defender keep turning off

Windows Security Essentials and Defender keep turning off. When I try a Quick scan it always stops with the message:


"Your PC couldn't be scanned. This program's service has stopped"


The Support info gives:

"Error code: 0x800106ba"


This only started happening today. I've tried uninstalling and reinstalling MSE but no change. I don't have any other anti-virus software installed.


Any ideas?


Thanks.

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.

 

Windows 10 - Security Essential installed and Defender turned off - cannot uninstall Essential

My Windows 7 has Security Essential installed. Upgraded yesterday to Windows 10 and keep getting message that Defender is turned OFF.

OK, I found out that no way to turn it ON, all greyed. Guess it must be conflicting with Security Essential. No way to turn off Essential. Tried uninstall it but keep getting funny eroor, "you cannot install Essential in this PC". I am not install, in fact
I am uninstalling ...

So this" Catch 22'' situation is due to Defender vs Essential fighting inside my PC while there is nothing I can do

1. I cannot turn off Essential

2. I cannot uninstall Essential

3. I cannot trun on Defender as long as Essential is in control

Any idea on how to get out of this situation?

Windows 10 Windows Defender versus Microsoft Security Essentials

I do not have Microsoft Security Essentials in that startup list. I only have Ms Security Client User Interface and Windows Defender User Interface in the list.
