What’s resmon.exe (Resource Monitor)? Is it safe or a virus?

Resmon.exe, or Resource Monitor, is a system utility in Microsoft Windows used to monitor and analyze system resource usage in real time. It provides detailed information about CPU, memory, disk, and network usage, helping users identify processes or applications consuming significant resources. Resource Monitor displays performance metrics like disk activity, memory consumption, and network connections, allowing users to terminate processes or troubleshoot performance issues. It is particularly useful for diagnosing system slowdowns and ensuring optimal performance. Accessible through Task Manager or directly via "resmon.exe," this tool is essential for advanced system management and maintaining system health.

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.
