What’s tar.exe (bsdtar archive tool)? Is it safe or a virus?

The tar.exe by Microsoft Windows is a command-line tool that is used to create, modify, and extract tar archives. A tar archive is a collection of files and directories that are bundled together into a single file.

This tool allows users to compress and decompress these archives, as well as perform various operations such as adding and removing files. It is commonly used in conjunction with other commands and utilities to manage and transfer files and directories in a more efficient and organized manner. Additionally, it allows for the preservation of file permissions and directory structures, making it a useful tool for creating backups and transferring large amounts 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.
