The first and last ones tell u how to stop it: "NOTE: TO BLOCK THIS TYPE OF WARNING DISABLE WINDOWS MESSENGER SERVICE". I'm surprised they put it there. Go to Administrative Tools, and then Services. The service you want to disable should be called "Windows Messenger" or just "Messenger". I somehow remember it being called "Windows Messenger", but on my computer, it's now being called "Messenger". Whatever the case, that's how to stop it. What you're seeing is actually a message sent to your computer from across the internet, so anti-spyware programs won't help.
