What’s mousinfo.exe (MousInfo.exe)? Is it safe or a virus?

mousinfo.exe is a diagnostic tool included with Microsoft's mouse and keyboard software, such as the IntelliPoint or Mouse and Keyboard Center packages. It is designed to verify that your computer is correctly receiving signals from your pointing device. The utility displays real-time data on button presses, scroll wheel movement, and cursor coordinates to help troubleshoot hardware issues.

You have this file because you likely have Microsoft-branded peripherals or have installed the specific drivers and customization software for them. It serves as a testing interface where you can confirm that every physical input on your mouse is being registered by the operating system. It is usually found within the installation folders for Microsoft hardware utilities.

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.
