What’s setx.exe (Setx - Sets environment variables)? Is it safe or a virus?

Setx.exe is a command-line tool in Microsoft Windows that is used to set environment variables in the system or user environment. It allows users to modify the system or user environment variables permanently or temporarily.

By using setx, users can define new environment variables or modify existing ones, which can affect the behavior of various programs and processes on the system.

This tool is commonly used by system administrators and power users to manage and configure the environment variables on Windows systems. It provides a way to automate the process of setting environment variables, making it easier to customize and control the system 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.
