After upgrade of MB from 2.2 to 3.0.5 the Realtime Protection Service will not start. It remains at "Starting" until the application is closed down. When re-opened, the service no longer says "Starting" but is now just off. All other services appear to be functioning. Also, scans take only a fraction of a second before they complete, reporting 0 items scanned.
I have uninstalled both the old and new versions, rebooted several times, removed by hand any old Malwarebytes program folders and registry entries. Re-installed MB 3 and still have same issue.
I am running Windows 7
