Windows 10: Can I disable defender since I have McAfee?

I am getting the error "Security Center failed to validate caller with error DC040780"


one of the answers (thread is locked) is to Disable defender.


I have subscription to McAfee, both antivirus and firewall and it is up to date.


Running services.msc and in elevated mode, all controls are grayed out for both Defender antivirus as well as the firewall.


I don't think I need more than one antivirus. This is Windows 10 pro with latest 1909 feature.

Conflict between McAfee and Windows Defender

Did you ask McAfee support (McAfee) and/or in their forum (McAfee Support Community)?

Try to

• uninstall McAfee
• run their removal tool (see List of anti-malware product removal tools )
• reboot
• re-install McAfee

In case Windows Defender is still not disabled after doing the above steps, either

disable Windows Defender manually (see the Answer-marked post of GreginMich in

this thread)

or

use a REG file (see Option 2 here: Windows Defender - Turn On or Off in Windows 10 )

 

How do I remove/disable McAfee and Defender so I can run AVG?

I noticed on my computer I have both mcafee and defender...defender doesn,t appear in the list of programs, I believe it is part of the operating system..Does anyone know how to disable it. I understand it isn,t a strong protector...Mcafee does appear
in my programs and I could delete it. I would like both of them to go away so I could put on AVG....

any suggestions

McAfee and Windows Defender

When a different antimalware protection product is installed, Windows Defender is disabled to make sure the two products do not interfere. In other words, McAfee tells Windows that McAfee is now protecting the system, and Windows therefore turns off Windows
Defender.

There should be an uninstall entry for McAfee if you'd like to remove the trial. Go to Start | Settings | System | Apps & features to find McAfee's entry. Once you click on it, there should be an Uninstall button that'll kick off the uninstall steps.
