It has been three days since I reinstalled Malwarebytes Anti-Ransomware Beta using the instructions above in this forum topic, and it seems to be working normally now. It no longer drops protection spontaneously, and it is operative every time I reboot without having to turn it on manually. When it says I am protected the green dot is present, as opposed to before when it would say I was protected in one area of the window but not in another area of the same window with a red dot present and not letting me start protection. Thanks for the help. If it misbehaves again, I'll report it in this forum topic.
