What’s VGAuthService.exe (VMware Guest Authentication Service)? Is it safe or a virus?

VGAuthService.exe is a process created by Broadcom Inc which functions as the VMware Guest Authentication Service. This service is responsible for authenticating users and managing communication between the host system and guest operating systems in a VMware virtualized environment. It ensures that the guest operating system is allowed to run on the host system and facilitates secure communication between the host and guest systems by managing user authentication.

VMware is a company that creates software for running multiple operating systems on one computer.

A virtual machine (VM) is a software-based emulation of a physical computer that runs an operating system and applications independently from the physical hardware.

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.
