MessageApp

What in the world is "MessageApp"? It causes me problems
with shutting down my computer, making it take forever
because it says it didn't close properly. I
never 'opened' it to begin with. I think its a bug that's
been causing a lot of problems with the other programs I
use. I need to know what it is and how to get rid of it
if its nothing necessary. Thanks in advance! Please
respond at because I'll never make it
back to this page...took forever to get here to begin
