What’s dbus-daemon.exe (dbus - FreeDesktop message bus system)? Is it safe or a virus?

`dbus-daemon.exe` is a core component of the D-Bus (Desktop Bus) system, developed by the FreeDesktop.org project. It facilitates inter-process communication (IPC) by providing a message bus system that allows applications and services to communicate with one another. Typically, it is used in desktop environments like K Desktop Environment (KDE) to manage and coordinate system events and processes, such as hardware notifications, application requests, or resource sharing. By acting as a middleman, it ensures efficient and standardized communication between applications and system-level components, enhancing the functionality and integration of the desktop environment.

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.
