I've been having the same problem ever for several months since I got this computer (Lenovo 310, Windows 10) and had Malwarebytes Premium installed. I have version 3.0.6. Sometimes it doesn't happen for days, sometimes several times a day. The "turn on" button in the error message doesn't do anything. In the protection settings, web protection is OFF. If I turn it on, it says "starting", and only once have I ever seen it switch to ON. But at least that stops the error message pop-up for a while.I've tried some of the tings I've seen on-line about changing the start-up settings and rebooting, but they don't help.
