What’s tcpvcon64.exe (Sysinternals TcpVcon)? Is it safe or a virus?

Tcpvcon64.exe is a command-line utility developed by Microsoft as part of the Sysinternals suite. It provides detailed information about active TCP (and optionally UDP) network connections on a system, including the local and remote addresses, connection states, and the processes associated with those connections. It is a lightweight, 64-bit version of the "netstat" tool, offering similar functionality with improved efficiency and integration with Sysinternals tools. Tcpvcon64 is primarily used by administrators and advanced users to monitor network activity, troubleshoot connectivity issues, or analyze processes involved in network communication on Windows systems.

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.
