I had the same false positives as documented here and in another thread. I found the source.
Looking at my log, my issue started earlier this month. The event always showed up every 12 hours. Once at 1:34 AM and 1:34 PM. so, I went and looked at Windows Scheduler.
Repeating task every 12 hours at 1:34 AM and PM was Brother PowerENGAGE. (It's written by a third party vendor. This same software is also included with drivers for certain Epson printers).
The day my events started showing up also happened to be on September 10th.
PowerENGAGE is a marketing tool produced by Aviata. It provides no actual function for the printer itself. The word salad on their website talks about "expanding your marketing universe". This program has its own entry in add/remove programs.
I uninstalled it last night and the alerts have stopped. If you are still getting these alerts in Malwarebytes, look in add/remove and see if you have Aviata PowerENGAGE installed. If so, uninstall it and see if this solves the issue for you.
I hope this is helpful.
