After uninstalling Malwarebytes Anti-Malware from a domain-joined computer, you may get the following error each time the computer reboots:

BusinessMessaging.exe - System Error
The program can't start because Qt5Widgets.dll is missing from your computer. Try reinstalling the program to fix this problem.

To resolve the issue, you need to manually remove a registry key using regedit:

  • On 32-bit, navigate to the key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
  • On 64-bit, navigate to the key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run

Remove the value with name Malwarebytes Anti-Malware.
