I have used Malwarebytes for scanning my systems many times in the past, and have been very grateful for its availability. About a week ago, I again wanted to make sure there's nothing untoward on my sytem, so I updated as usual and scanned, but this time said yes to the activation of a 14 day trial of the full version. Soon I had to realize I was more or less unable to use the internet in any meaningful way, as many actions were blocked. No warning messages were displayed, but disabling Malwarebytes enabled these functions again. So I disabled all TSR aspects of Malwarebytes, keeping only scheduled scans, every 3 days at night. This evening I was playing a game, and was just about done with some heavy fighting the AI, when a popup flashed. I had just enough time to see "Malwarebytes" and "quarantine" and "reboot" (or was it "restart"?), and the screen turned blue, "Shutting down" (in fact, the German version) with dots circling. At that moment I realized I had made a number of changes to a Word file still running in the background which I had not saved. After reboot, I checked how such behaviour could be avoided in the future. I was unable to locate any type of corresponding switch or setting, nor was I ever asked whether I want this to happen. Unbefrigginglievable. I may have made major mistakes in the process, but I do believe Malwarebytes should set up the program more foolproof than that.
