(Microsoft)
Microsoft Agent Server. Microsoft Agent Server is an ActiveX control which software developers can use to add character animation to their software or web pages, text to speech facilities, or end-user voice commands capability. In layman terms it is Microsoft software which other programmers can use to talk to you, display a talking animated character, or listen to voice commands from you. The most famous of those animated characters is that "paper clip" Microsoft Office assistant which most users turn off.
Recommendation :
If it is running in your Task List then it is because some software you are using requires it. Leave alone.
