This morning I found something odd sitting on my desktop, it was a spam ad but this was done through Messenger Service(not MSN Messenger). I didn't really think much of it at the time but later I found reference to it in Event Viewer. What I want to know now is how do I stop this type of message. I had to reinstall recently due to ha hardware failure so I am still tweaking my settings back to the way they were, this may be why this has never happened before. If there is something I need to disable or a firewall setting I've forgotten about. Below is the Info from the message from Event Viewer. Event Type: Information Event Source: Application Popup Event Category: None Event ID: 26 Date: 10/15/2002 Time: 3:02:07 AM User: N/A Computer: COMPUTER Description: Application popup: Messenger Service : Message from WEBPOPUP05 to 18.104.22.168 on 10/15/2002 3:02:07 AM U N I V E R S I T Y D I P L O M A S Obtain a prosperous future, money earning power, and the admiration of all.

The Messenger Service was enabled, I clearly remember disabling it a few days ago while making some other changes, anyway, this service allows anyone to send messages to your computer using your IP. The service doesn't even check the source of the message.
