What’s InstallFlashPlayer.exe (Adobe® Flash® Player Installer/Uninstaller 11.3 r300)? Is it safe or a virus?

InstallFlashPlayer.exe by Adobe Systems Incorporated is an executable file designed to install or uninstall Adobe Flash Player, a software application that enables the playback of multimedia content, interactive features, and animations embedded in websites or applications. The version mentioned, "11.3 r300," refers to a specific release of Flash Player. The application manages the installation process to integrate Flash Player into browsers or systems, allowing them to render Flash-based content. It also facilitates the removal of Flash Player from a system if uninstallation is required. Given Adobe has discontinued Flash Player, this file is obsolete and unsafe to use today.

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.
