What’s iissetup.exe (IIS Setup)? Is it safe or a virus?

The `iissetup.exe` file is associated with Microsoft Windows and is responsible for the installation and configuration of Internet Information Services (IIS), the web server platform provided by Windows. IIS allows users to host and manage websites, web applications, and services on their computers or servers. The executable helps set up required components, configure the services, and integrate IIS with system resources. It often runs during the initial IIS setup or when adding IIS as a feature to a Windows system. Proper execution of `iissetup.exe` ensures stable operation of IIS for hosting web-based content and applications.

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.
