What’s Bootstrapper.exe (Bootstrapper.exe)? Is it safe or a virus?

Bootstrapper.exe is a generic executable file developed by Microsoft Corporation, typically associated with the installation or initialization process of software applications. It acts as a setup program framework that prepares the necessary resources and dependencies required for a software application to run or install properly. Bootstrapper.exe is often seen in software deployment processes using technologies like the Microsoft .NET Framework or Visual Studio, where it ensures prerequisite components, such as libraries or runtime environments, are installed before the main application. Being an essential part of the setup utility, it facilitates smooth software installations across compatible 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.
