What’s coregen.exe (Microsoft Common Language Runtime native compiler)? Is it safe or a virus?

The coregen.exe is a software program developed by Microsoft and is part of the Windows OS itself, and compiles CLR.

The Common Language Runtime (CLR) is a key part of Microsoft's .NET Framework. It acts like a virtual machine, overseeing the running of .NET applications. The CLR uses something called just-in-time compilation, which means it takes the program's intermediate code (a kind of half-way step code) and turns it into instructions that the computer's CPU can understand and run.

Below are 4 simple steps you can take to see if the coregen.exe process is safe or malware.

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.
