This move by Adobe is a great step toward securing Mac users from known vulnerabilities in Flash, and will ensure that users will always be running the latest versions. Therefore, if you suspect a computer may be affected by malware and are investigating the system's various LaunchAgents and LaunchDaemons folders, if you see the presence of the "" file that targets the "fpsaud" program then do not be alarmed. While this update scheme is beneficial, it might at first glance appear alarming to some people who have researched Flashback and other recent malware attacks on OS X, where malicious programs have used similarly named launch agent files that have targeted small updaters and installers in similar ways. The installation of the new version is silent, so users will not be prompted to download, and will instead be automatically updated to the latest version. When fpsaud opens it will check the current version and the available version for the presence of an updated Flash player version, and will then install it if needed. This causes the system launcher (launchd) to open a small program called "fpsaud" (likely standing for Flash Player Silent Auto Updater) which is located within the Adobe Flash install manager utility. The automatic updating works by using a launch daemon called "" located in the /Library/LaunchDaemons/ folder. By default it will have Flash automatically download and install the latest version. When installed, the updater will request that you choose from the 3 autoupdate options. The update behavior options can be changed in the Flash Player system preferences pane. If you choose the option to updates automatically, Flash will check for updates on a daily basis and install them in the background.

When you download and install Flash 11.3, the installer will offer you to have Flash automatically update, only notify you of available updates, or never check for updates. To tackle this and work to keep most people keep up-to-date with Flash, Adobe has implemented this new background-updating feature.
