What’s BCILauncher.EXE (BCILauncher)? Is it safe or a virus?

BCILauncher.EXE is a program created by Microsoft that's made specifically to launch the Bing Chat Installer app BingChatInstaller.exe.

Then after BCILauncher.exe launches BingChatInstaller.exe, the Bing Chat Installer can make Bing your default search engine if you accept the change to Windows. This launcher appeared in the KB5033372 Windows OS update.

Many people have reported on Reddit and other websites that they find this Bing pop-up from Microsoft annoying. To stop this Bing pop-up ad from constantly appearing on your PC, install the free SpyShelter app, then next time the ad appears search for BCILauncher.exe in SpyShelter, then click its app icon, then click "Quarantine". Now the Bing ad can never appear again because BCILauncher.exe is no longer allowed to start.

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.
