MBAM disables Windows Defender after WinUpdate 1903 installed

Recommended Posts

Running M3 v3.7.1 on 64x Win10 Pro.

 

I installed Windows Update v1903 tonight and, now Windows Defender AV is disabled and Windows Defender AS is enabled. Also, Windows Defender is no longer listed in context menu of File Explorer. Before installing this WU 1903 update, Windows Defender was fully enabled along side of MBAM real-time protection and custom scanning with Windows Defender was an option in the File Explorer context menu. Yes, I have rebooted several times after Windows Update.

The following is from a FRST log:

AV: Windows Defender (Disabled - Up to date) {D68DDC3A-831F-4fae-9E44-DA132C1ACF46}
AV: Malwarebytes (Enabled - Up to date) {23007AD3-69FE-687C-2629-D584AFFAF72B}
AS: Windows Defender (Enabled - Up to date) {D68DDC3A-831F-4fae-9E44-DA132C1ACF46}

 

Please tell me how to re-enable Windows Defender and add it to the context menu.


Thank you

DW

Change Malwarebytes to never register in the action center.

Hi Jerry,

Thanks for the quick reply.

Both MBAM and Windows Defender are now showing in the context menu. FRST log shows the following (no menti0on of MBAM):

AV: Windows Defender (Enabled - Up to date) {D68DDC3A-831F-4fae-9E44-DA132C1ACF46}
AS: Windows Defender (Enabled - Up to date) {D68DDC3A-831F-4fae-9E44-DA132C1ACF46}

When I set Action Center to "Never Register" I saw a notification saying Windows Defender and MBAM are both turned off. That's obviously false with respect to WD, however, I'm not sure that MBAM is still fully active (providing real-time protection). Here's a shot of my MBAM Dashboard:

Please confirm that MBAM real-time protection is indeed still fully active.

Thank you,

DW

Hello,

Setting Malwarebytes to "never register" in the Windows Security Center has no impact on the Real-Time Protection provided by the program.

The issue you've encountered is something we're aware of and will be providing a fix for in an upcoming version of Malwarebytes. Note that when Windows Defender is the only other security product installed, the expected default behaviour is for Malwarebytes not to register in the Windows Security Center. The fact Malwarebytes did register when set to default settings is the issue that we will be addressing.
