My old desktop computer is running Windows XP. New one is on the way, but for now I'm still using the old one. Recently, when I boot up Windows has taken to starting MSN messenger without my permission. If I close the pop-up Messenger window, I get a message telling me the Messenger is running in the background so I can receive messages. Of course, nobody sends me messages, and I don't WANT to receive messages.
How can I kill this -- permanently?
