What’s PPTVIEW.EXE (Microsoft Office PowerPoint Viewer)? Is it safe or a virus?

PPTVIEW.EXE is an executable file developed by Microsoft Corporation that functions as the Microsoft Office PowerPoint Viewer. It allows users to view, read, and print PowerPoint presentations (PPT and PPTX files) even if they do not have Microsoft PowerPoint installed on their computer. The application provides a simple interface to open slideshows and view them in full-screen mode, preserving the formatting and animations. However, it does not support editing or creating presentations. This tool is particularly useful for users who need a lightweight way to access PowerPoint files without requiring the full Office suite.

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.
