What’s lib.exe (Microsoft® Linker Stub)? Is it safe or a virus?

Lib.exe is a command line utility developed by Microsoft Corporation that is used to create and manage static libraries in the Windows environment.

It allows developers to create libraries containing object files which can be linked with other programs to provide additional functionality. The tool can also be used to add or remove object files from an existing library, update time stamps, and perform other library-related tasks. Lib.exe is a valuable tool for developers who need to manage and organize their code into reusable, shareable components, and is commonly used as part of the software development process in Windows-based environments.

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.
