What’s tcpview64.exe (Sysinternals TcpView)? Is it safe or a virus?

Tcpview64.exe, part of Microsoft’s Sysinternals suite, is a 64-bit Windows utility designed to provide detailed information about active TCP and UDP network connections. It displays processes on a system along with associated network endpoints, including local and remote addresses, ports, connection states, and the process owning each connection. This tool is useful for monitoring real-time network activity, troubleshooting connectivity issues, detecting malicious activity, and managing network resources. By offering a user-friendly interface, TcpView enhances the visibility of network behavior over what Windows' built-in Netstat command provides, making it valuable for IT professionals, system administrators, and security analysts.

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.
