Windows Defender keeps stopping

[nobodyuknow]

This is happening on multiple W-8.1 64-bit PCs, some with Office but others without. I install Windows. I run Windows Defender. I install MBAM 3. Days later (there's no pattern), I try to start Windows Defender but it tells me that it cannot start. The only solution is to deactivate MBAM, update Windows Defender and run scans, reboot, reactivate MBAM. This has happened since the first version 3 and on all versions since.

The worst part is that Windows Defender never notifies me that it has stopped. The only way I know I know is when I try and start it.

I also have a W-7 64-bit system with Bitdefender Free and MBAM 3 that does not appear to have this problem.

 

Any suggestions?

Change this setting to never register.

Thanks! I will change that on all systems immediately.
