What’s windivertctl.exe? Is it safe or a virus?

Windivertctl.exe is a command line tool developed by Cloudflare, Inc.

It's used to manage the Windows Packet Divert (WinDivert) driver, which is a user-mode packet capture and manipulation library that allows applications to capture and/or manipulate network packets in Windows. With windivertctl.exe, users can install, uninstall, enable, and disable the WinDivert driver, as well as manage its settings and filters. This tool is particularly useful for network administrators and security professionals who need to perform packet-level analysis, filtering, and modification on Windows systems. It provides a convenient way to control and customize the behavior of the WinDivert driver to suit specific network monitoring and security requirements.

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.
