What’s IISexpressSVC.exe (IIS Express Service)? Is it safe or a virus?

IISexpressSVC.exe is a process associated with Lansweeper, a network management and asset discovery tool, and is identified as "IIS Express Service." It functions as a lightweight version of Microsoft's Internet Information Services (IIS) used to locally host the Lansweeper web interface. This service facilitates communication between Lansweeper's database and the web console, allowing users to access and manage network information through their browser. By using IIS Express, Lansweeper provides a self-contained environment for web services without requiring a full IIS installation, simplifying deployment and ensuring compatibility with Windows systems for seamless performance of administrative tasks.

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.
