Hello There was an issue with corrupted database packages earlier today that affected some 64-bit systems resulting in disabling the real time protection for these machines. This problem has since been addressed. To get things working normally again simply open Malwarebytes and click on "Current" next to where it says Updates in the Dashboard and it should download and install working databases. If it is able to successfully update but protection still is not working, then please try right-clicking the Malwarebytes tray icon next to your system clock and select Quit Malwarebytes. Open Malwarebytes once again from your START -> Programs menu or from the shortcut located on your Desktop. If the issue persists, then please try restarting your PC. If you have any further issues, please let us know. Thank you again for all your patience, we really appreciate it and thank you for using Malwarebytes. *_Customer Success_* !https://www.malwarebytes.com/images/staff.png!
