Defender updates failed error code: 80070005

Question

Split from this thread.

This didn't work for me though I have no other anti-virus or anti-spyware installed.

What else can I try

Answer 1

@scottjameswilson -

Can you post a screen shot of the following log file with the error code from here : \windows\temp\mpsigstub.log

You should see the same error code (80070005) in the log.  This will help me understand when you see access denied error.

Answer 2

If you haven't already - can you try executing the following command (from an elevated command prompt) : "%programfiles%\windows defender\MpCmdRun.exe" -wdenable

If this doesn't work - do let me know what 'Virus Protection' is displayed in the 'Security' section of Security Center.  Windows Defender will not launch if there is a 3rd party registered.

Answer 3

I also tried the following suggestion:

1.      Press Windows Key + R

2.      Type regedit

3.      Locate the following path *HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS DEFENDER*

4.      Right Click this file and select permissions

5.      Press Advanced

6.      Where it says owner press change

7.      Change the owner to your username

8.      Now press applythen ok

9.      Select Full Controlfrom the permissions menu

(Click the Windows Defender folder)

10.  Find the value Disable AntiSpyWare and Disable Antivirus and set these values to 0

(Explanation: double click each and where the 1 is put 0 and press ok)

11.  Open services.msc

12.  Find Windows Defender

13.  There should be 2 services: Windows Defender Serviceand Windows Defender Network

14.  Right click each and press start

15.  After you have started both restart your computer

16.  Run Windows Defender

Do keep us updated.

This did not work as user but as admin it worked for two minutes or until reboot and then the registry entries were back to 1,1

I repeated it three times with the same results each time.
