Windows Defender "sees" MB as not running after last update

[dg1974it]

I'm running W10PRO with latest patches (for Meltdown/Spectre).

After the restart, now Windows Defender complains about MalwareBytes and says that it's not running (text is in italian, sorry):

but MalwareBytes is running and up-to-date (I hope! no update if I do the "update now" manually):

any ideas?

I'm also running Avast Premier but didn't found any issue with Windows Defender.

Currently, this is expected behavior with Windows Defender Security Center. Could you check your "Security and Maintenance" section to make sure everything is registering correctly?

 

To get to Security and Maintenance, go to the following:

Control Panel > System and Security > Security and Maintenance

 

Thank you

in Control Panel -> System and Security -> Security and Maintenance everything is "Ok", but when I clink on the link in the red box:

a window pops up saying that MalwareBytes is "Disabled" (and all the below buttons are disabled).

Prior to the latest Windows Update (http://www.catalog.update.microsoft.com/Search.aspx?q=KB4056892) I never had this issue (and I never saw that window in the Control Panel).

oookey.

I don't know what happened, but after I took those screenshot, I decided to reboot my PC, and now Windows Defender doesn't complain anymore and under Control Panel now MalwarBytes is "Enablad".

well... why? LOL!

Could you get us some logs just so we can double-check and ensure everything look ok. Check my signature for information on how to get logs. Make sure to get FRST and MB-Check logs. 

Also, ensure Avast has Malwarebytes set in exclusions as that can cause some issues.

I've generated the logs but I think there are too many "personal" information in those txt.

I don't think that attaching the mb-check-results.zip file in a "public" forum is a "smart" idea.

There is nothing in them to harm you but please pm the zip file to @vbarytskyy if you are concerned. Might make the fix take longer since only he can see those and offer advice.

ok, here the logs.

 

PS: I never had to "exclude" MB files in Avast since 2014 when I installed both programs on my PC, so I didn't change anything this time. After another shutdown -> power on, everything looks still fine. Windows Defender is "all green", MB is "active" and "all green", etc. I don't know why after the KB4056892 for two days Windows Defender was complaining about MB not being active.

Yes, as I said at post #4.
I don't know why after the KB4056892 for two days Windows Defender was complaining about MB not being active, but since yesterday everything is working.

Thanks for the update and your continued support of Malwarebytes.
