I have this issue on numerous customers computers. It only happens after installing (clean) or upgrading to Malwarebytes v3. It does not occur on all PCs but it seems more prone to occur on laptops which are (soon if not already) more common than desktops. Thanks to nickcydiaa for the work-around, I am now able to perform a full scan on the impacted systems. I have not found a common factor for this issue, impacted systems have different OS, hardware, AV (or none), clean installation vs upgrade, etc. Version 2.xx worked on many of these systems, this only occurs with v3. I can check the left boxes for what to scan for but the Drive boxes cannot be checked on systems with or without touchscreens. The work-around makes it appear the issue is with the App not responding correctly with the mouse location/button press combination.
