Eddy, if you read the article I posted, you would have seen that it states that it is the Messenger service built into Windows, not any form of "Instant Messaging" service, such as MSN Messenger, AIM, YIM, ICQ, or any other equivalent.
This is a service built into Windows that allows users to send/receive broadcast messages within a local network. You can send yourself a message by opening a DOS prompt, and typing the following:
This communicates over IP, and is an integral part of Windows. Thus you cannot remove the Messenger service (well, you can, on NT/2000, but you need to remove the "Workstation" network service, and then you're looking at a probable rebuild). This is also the reason why I suggest that blocking the specific messenger port on the firewall would help, not least because your own in-built notifications will still work, whilst those coming from outside the machine will not.
Like I said, I'm looking into it, but don't bother removing your IM services as this will merely inconvenience you without solving the problem.
