What’s MB-SupportTool.exe (Malwarebytes Support Tool)? Is it safe or a virus?

MB-SupportTool.exe is the main executable for the Malwarebytes Support Tool, developed by Malwarebytes Inc. This utility is designed to assist users in troubleshooting, repairing, and, if necessary, uninstalling Malwarebytes software from their systems. It's particularly useful when standard uninstallation methods fail or when deeper system diagnostics are required. The tool can perform a clean removal of Malwarebytes products, gather logs for support, and reinstall the application if needed. It's commonly used in both personal and business environments to address issues related to Malwarebytes installations.

If you find MB-SupportTool.exe on your system, it's likely because you or someone else installed it to manage or troubleshoot Malwarebytes software.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
