I've used Malwarebytes (Pro version) since it was first developed. Personally, I've had very good experiences with the program over the years, except for its constant problem of failing to automatically update. And, it does not matter what "Scheduler" settings I use (I have it set to "Realtime"). Sure, you can right-click on its System Tray icon and click the "Check for updates" option, but this certainly is not an ideal option -- particularly when one is *paying* for the "Pro" version of the program. This issue seemed to be briefly addressed in the previous version (1.60) however, it has defaulted back to this behavior with the current 188.8.131.520. I wish this ongoing issue would once-and-for-all be remedied by Malwarebytes' programmers, because it's getting tiresome. As a computer technician, this is a key concern because my clients oftentimes will not remember to update the program.
