What’s memtest.exe (Memory Diagnostic)? Is it safe or a virus?

Memtest.exe is a utility program by Microsoft Windows that is used to test the memory (RAM) of a computer system for errors.

When run, it performs a comprehensive scan of the system's memory to detect any potential issues such as bad memory cells or corrupted data. This tool is helpful in diagnosing and troubleshooting system instability or crashes that may be caused by faulty memory. It provides a non-destructive way to thoroughly test the integrity of the computer's memory, ensuring that it is functioning properly and reliably.

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.
