Depending on your definition of "dangerous". It is a useless resource hog and can cause crashes. This file is part of the Transponder spy/ad ware. It pulls ads from the Internet and puts up at least two pop ups every time you start Internet Explorer. To delete, you must first unregister it and then reboot your computer.
