It is a legitimate program used to help remotely identify and repair problems in computers.I have used it on occasion when I had no personal access to an "ailing" computer and the owners of the computers needed assistance. There are two versions - one installs in your computer as a program and the other is downloaded to the desktop where it can be accessed.

Look in Control Panel and look for the icon on your desktop.
