What’s BingChatInstaller.EXE (Microsoft Bing)? Is it safe or a virus?

BingChatInstaller.EXE is a file used to install Microsoft's Bing Chat application on a user's computer.

When run, it asks the user to switch to Bing as the default PC search engine, and this notification may appear in other browsers besides just Microsoft Edge. For example, it may appear in Chrome, according to screenshots seen on Reddit.

Many people have reported on Reddit and other websites that they find Bing pop-ups from Microsoft annoying. To stop the Bing pop-up ad from constantly appearing on your PC, install the free SpyShelter app, then next time the ad appears search for BingChatInstaller.exe in SpyShelter, then click its app icon, then click "Quarantine".

Now the Bing ad can never appear again because the BingChatInstaller.exe is no longer allowed to start, and can no longer install these types of ads on your PC.

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.
