It's almost certainly unwanted traffic. These ports are used by the
messenger service (something internal to Windows, not to be confused
with Windows/MSN Messenger). It allows a pop-up message to appear on the
desktop, hence spammers are trying to use this to send spam straight to
the desktop.
I get a few thousand of these per day blocked by my firewall - a common
source address appears to be 218.83.155.175.
