url.dll getting quarrantined

Recommended Posts

We have an Export to Excel function on our ERP that apparently nobody has used to this point - so the new guy that first tries it ends up getting a popup saying that MWB is quarantining url.dll - I've atatched screenshots of the messages.

 

The question is, do I just create a blanket exception on url.dll or is there a better way to get around this?

Also, I'm getting a "failed to restore from quarantine" message. when I try to restore it.  How do I get around this?

Additional into... I found that if I disable "Protection for Office WMI abuse" under anti-exploit protection, it works.  So how would I go about correcting this without opening this up wide open?

Urgh sorry, not that setting but rather "VBA 7 Abuse".

 

Wish we could EDIT our posts in this forum rather than keep adding replies :)

OK well it's not that either then.  I disabled the option, saved the setting, then cycled the service and it seemed to work but after a reboot it's back to being blocked, so I suppose something is happening with cycling the service which is not blocking it right away.

No problem at all.  Thank you for the update, I am glad you were able to resolve the issue.  In the meantime I have made a note of your report and will be submitting it to the Product team for review in case any changes need to be made to correct the FP/detection.

Hello @Kernel

Glad you were able to get this resolved.  When you get "Failed to restore from Quarantine"  you'll want to verify that the endpoint is indeed online and communicating with the cloud console via the "Malwarebytes Endpoint Agent Service."

Warm Regards,

I would also suggest that it is possible that the endpoint needs to be rebooted prior to restoring an item from quarantine as often times Malwarebytes will mark active items quarantined for Delete On Reboot and prevents them from being restored prior to a reboot taking place in order to avoid accidentally removing a file completely with no backup copy existing in quarantine.  I don't know if that is the case in this instance but I suspect it could be.
