This is a cross post out of general interest to security basics.
Firstly you have to wonder why someone is running this service.
I personally only found out after using a ports traffic analyzer. I will
pass the url for the program on if you want it but do not want to be seen
to plug if against the rules of the forum. :-)
Secondly Windows Millenium installs the service without telling you that it
has done so when you do a basic install.
Remove it using Control Panel, Add/Remove progs ,windows setup.
communications, ckick on Universal plug and pray, (sic) and then apply.
