Strange PNR error

Specs: Windows XP
Ok so I have been running one anti virus tool on my PC after another after getting this error, and am absoutely worrid about it.

Suddenly got a pop up window saying "The PNR number has a maximum limit of 45 characters. Please contact.." went on about contacting administrator.

It was a grey popup window, with no heading, so not sure if it was from an app, or web browser, etc. Also, there was only an OK button at the bottom and no option to cancel. I am paranoid about hackers etc. Has anyone seen this sort of message before?

It could be someone using the "Messenger" service to send hoax messages to your desktop. This service has nothing to do with MSN Messenger or Windows Live Messenger.

The service was included for office network environments to send messages from one terminal to another, but it's also being used to send spam messages over the internet.

All home users should disable it (it's disabled by default in XP-SP2 & SP3). You can disable it this way:

Start >> Run - type SERVICES.MSC

Scroll down till you find MESSENGER

Double-click it.

Set 'Startup type' to DISABLED

If 'STOP' button is not greyed-out, click it to stop the service.

Click 'OK'

If that service was being used for those pop-ups, you shouldn't get them any more.
