Yahoo Messenger

What is Yahoo Messenger?

Is a downloadable casual PC game distributed by Yahoo! Games.

Overview

Yahoo Messenger is a program developed by Yahoo!. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. It adds an extension to the user's Internet Explorer web browser. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The software installer includes 35 files. A majority of the PCs this is running on, most OS versions are Windows 7 (SP1). The distribution of this has mostly been seen in the United States.
