Error DC040780


Recommended Posts

Hi there,

Every time I boot my PC, I get this error "security center failed to validate caller with error DC040780".

I'm on Windows 10 home 64bit 1809 ( build 17763.316 ) and using immunet

Security center says it can't check the virus protection status and I have to open immunet for more information.

Both Immunet and my PC are working fine.

Hi Jon79, have you tried to add exclusion rules for Immmunet's processes which are sfc.exe, iptray.exe (and freshclam.exe if you have the ClamAV module enabled) to Win 10's Security Center?

Info on how to create custom allow rule sets for Security Center can be found at this Microsoft Knowledge Base article if you're not sure how this is accomplished. https://support.microsoft.com/en-us/help/4028485/windows-10-add-an-exclusion-to-windows-security

Hi ritchie58,

thanks for your answer, but I think your suggestion is to set an exclusion on Windows Defender rather than on Security Center. Well, I can't do it because Immunet disables Windows Defender, so "Manage settings" is not available.

I think the problem is that Immunet can't set itself as provider of virus and threat protection in the security center, so the security center can't check Immunet status.

In attachment you can see the difference of security center icon with Windows Defender and with Immunet

Hi chaozz,

it could be, but with other AVs I only got the "status unavailable" on "virus & threat protection", with Immunet I also get the error on Event Viewer.

By the way, it's not a big deal, as I said both Immunet and my PC are working fine (my PC is super fast actually :) )

as of right now, I cannot re-produce this error at all.
Though, it could be because I am using an older windows defender (I am upgrading the version right now)
I've made sure that SecurityCenter is running-

googling shows a ton of people having issues with any anti-virus product installed along side windows defender though, which is what @chaozz said.
It could very well be Windows SecurityCenter not playing nice. Though, I will still try and get this to error for me.

Thank you very much for reporting this Jon.  I've successfully reproduced it, and at this point my only advice is to  steer clear of win 10  1809.   as far as I can MS pulled it  after release due to driver incompatibilities and potentially deleting user data when upgrading from previous versions.  I was able to obtain a 1809 iso through MSDN  and it ended up bootlooping  during install  of both home& pro win 10 versions (installing to vmware workstation).   I had to use a workaround  just to complete the OS install:  https://luyentap.blogspot.com/2017/10/windows-installation-cannot-proceed.html.  After that I was able to  install Immunet and repro your bug.
