Many thanks. As it is shown under "General Settings", I had assumed that meant start Malwarebytes with windows, not just the protection. I think the wording is poor and the general appearance of the program could be improved. It wuld also help if the taskbar icon changed a little when acticve protection is disabled. However the scanning and updating is very good. I have also noticed that if the active protection is enabled, some programs will not start at all, including Roboform. I assume that this is a conflict between NOD32 and Malwarebytes. I therefore use Malwarebytes as a scheduled daily scanner.
