In my opinion, it appears that Malware ver 1.37 with the paid protection module has a problem. I believe the problem can be narrowed down to the mbamservice.exe program. I've followed all of the instructions for a clean install, uninstalling malawarebytes, downloading and running the mbam cleaner program. I've also excluded the appropriate folders and files from scanning by my antivirus software as instructed to from this forum. Thought everything was working fine...but NOT. After a few days, I'm now seeing problems at boot up. Mbamservice terminated unexpectedley and would not start. Windows event viewer reports: The description for Event ID ( 1 ) in Source ( MBAMService ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: MBAMService, mbamservice.exe: LoadLibrary failed with error code 998. Now trying to load the normal Malwarebytes program I get Error loading database line #0 (0) OK, Malaware tech support team... its really time to step up to the plate and look into the problems with mbamservice.exe from version 1.37. Apparently this is a whole new version with major upgrades. As a computer technician, I am responsible for managing the integrity of about 200 computers for various clients. 100 of them use Malware bytes paid version ... 33% are reporting problems, lock ups, etc. where I've had to uninstall and/or disable the software to get the computer going. I liked the product (past tense) until version 1.37. Now I'm about ready to move on. Tech support: I'm willing to work with a couple machines to isolate the problem but I don't have the luxury of traveling to all my clients to isolate the problem on all computers, and my clients are getting angry that I sold them a poor product. Clearly, there is an issue with mbamservice in version 1.37 Let's get problem fixed or revert back to the engine from version 1.36. Thank you
