I faced problems with MBAM 3.0.6: "Unable to connect the service". Using F-Secure Safe. Both programs are "latest versions" and OS is Windows 10 (Finnish) with the latest upgrades.
Problem is not, I think F-Secure: Both safes run smoothly until W10 Update last week. Something caused "too long startup procedure" to Malwarebytes service. Not even "delayd start" was successful.
My quick patch was a .cmd file on desktop (run 'As administrator'):
net stop "Malwarebytes Service" /y
net start "Malwarebytes Service" /y
After restarting the service, it takes som 30sec to MBAW 3 start normally.
