Access History in hive?...

[shiromar]

Getting a bunch of events showing up I want to be sure isn't a sign of a larger issue. 

This is what I'm seeing in Event Viewer

The access history in hive \??\C:\PROGRAMDATA\MALWAREBYTES\MBAMSERVICE\S-1-5-18-11122018180023188-ntuser.dat was cleared updating 0 keys and creating 0 modified pages.

Greetings and welcome,

Unless I am mistaken, I believe those .DAT files being referred to are backup copies of your system's registry hives created by Malwarebytes during a scan of the system (something it does to allow it to scan all user accounts on the system and their associated registry hives to detect/remove malware regardless of which user account that malware may be installed under) which Malwarebytes then deletes once the scan completes if no threats are detected.  I believe it is a safety measure and also has something to do with how Malwarebytes handles deleting items detected under other/offline user accounts for scans so it shouldn't be anything to worry about.

With regards to mwac.sys, this is the Malwarebytes driver used for the Web Protection component so it is normal for it to show up and register/activate and load into memory whenever Malwarebytes loads its protection and I also believe that it reloads this driver whenever Malwarebytes is started and may also unload/reload the driver following any database updates to refresh the Web Protection database and clear the cache (to add the new blocked sites into memory and remove any from memory which may no longer be blocked following database updates).

I hope this helps explain things a bit, and if anyone from the Malwarebytes staff has any further insights and/or corrections, then I concede to their knowledge as my personal knowledge on the subject is somewhat limited, however I did work for Malwarebytes in the past so I am familiar with much of its technology, however things may have been changed since that time and there may be more that I am not aware of.

Please let us know if there is anything else we might answer for you or assist you with and if you have any further questions about these entries.

Thanks
