I didn't find a clear answer to my two queries and would be grateful to the community for answering them:
Malwarebytes Endpoint Security was purchased in January 2018 which continued use of the product. MBAM is date stamped 2016-02-09 version 184.108.40.2062. For reference, if it helps, I clicked on the link in my original order and included a screenshot of the files.
I would have expected an update as my licence expires 2019 - is 220.127.116.112 still the latest version?
In addition, as I run MBARW alongside MBAM (unmanaged), I remember reading last year that was to be integrated but see no such option to enable/disable in MBAM and my presumption is that because its an older version it doesn't have this feature?
