What’s MapSource.exe (MapSource Application)? Is it safe or a virus?

MapSource.exe is an application developed by Garmin International intended for managing and transferring GPS map data. It allows users to view, edit, and transfer maps, waypoints, routes, and tracks between a computer and compatible Garmin GPS devices. The program provides tools for trip planning, navigation customization, and organizing geographic data visually using detailed maps. It enables users to install or update maps on Garmin devices, ensuring accurate and updated navigation. While MapSource has been largely replaced by newer software like Garmin BaseCamp, it was a key utility for older Garmin GPS devices to manage geographical information efficiently.

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.
