Windows 10: Windows Security/Defender won't stay open

Often, when I'm away from my computer, my Windows Security/Windows Defender antivirus software closes itself, even though I prefer for it to be open all the time. I've checked the settings in the program, but can't find anything related. Advice? Thanks in advance.

Windows Defender Security Center Won't Stay Open

Thanks @Hydrate! Followed Step 3 of Option 2 and rebooted ... problem solved!

I'll keep an eye on it for the next couple of days and if all stays good, I will mark this thread closed.

 

Windows Defender Security Center Won't Stay Open


When I open Windows Defender Security Center, it opens and then closes itself.

I’m running Windows 10 Home, v1703, with the latest updates.

I run Norton Security as my primary AV & firewall with the latest updates.

I did a system reset in the last couple of months.

I have the latest Defender updates according to: https://www.microsoft.com/security/p...tions/adl.aspx

Defender seems to be functioning, but generating the following errors:

• Event ID 3: The Windows Security Center Service was unable to establish event queries with WMI to monitor third party AntiVirus, AntiSpyware and Firewall.
• Event ID 16: Error while updating Windows Defender status to SECURITY_PRODUCT_STATE_ON.
• Event ID 1000:

I have tried options 3 and 5 in this tutorial: Turn On or Off Windows Defender Real-time Protection in Windows 10. Options 1 and 2 aren’t available to me since the settings window won’t stay open. Option 4 isn’t available for Windows Home.

As I said above, AFAICT, Defender seems to be working, but the Defender Security window won’t stay open and it’s generating a lot of errors.

Any suggestions for troubleshooting and/or fixing this issue?

None of your screenshots work. I suggest uploading them to tinypic.com or imgur.com and then posting a direct link within your post please.

Screenshots would be helpful.
