computer freezeing after latest update

[k9cop]

when ever I shut down malwarebytes via ctrl alt delete after I right click exit on task bar icon to exit, my computer will stop responding, this has never happened before last update .

This is quite normal. The service mbamservice.exe is not supposed to be stopped after the protection module has been enabled, even if the protection module is later disabled. The reason being that it uses a kernel mode filter, and killing it can cause system instability, such as the system freeze you mention (I've seen similar behavior on my own systems, even with several previous versions of Malwarebytes in testing).

If you do not want the service to be using CPU/RAM (but still wish to use the Scheduler), then I would recommend unchecking Start protection module with Windows. in the Protection tab.
