What’s unrar.exe (Command line RAR)? Is it safe or a virus?

Unrar.exe by WinRAR GmbH is a command-line tool designed to extract files from RAR archives. It allows users to unpack and retrieve compressed data within RAR files directly from the command prompt, making it suitable for automation or use in scripts. As a lightweight and non-GUI tool, it solely focuses on decompression (unpacking) rather than creating or modifying RAR archives. The application is widely used to access archived content on systems without graphical interfaces or when users prefer scripting solutions. It supports various RAR file formats, including older and modern versions, ensuring compatibility and efficient extraction of data.

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.
