popups

There have appeared these strange pop-ups on my computer, saying it's a Messenger service at the top of each pop-up. They appeared first some days ago, and the first one said that I had to visit some link(www.messengerservice.info) where I would find tools to remove this Messenger Service. Now...

Anyone notice that some pop-ups have found a way to defeat the blockers? Or is just me?

Hi everyone, I am having a problem with "Gator" Corporations legal virus on my fathers computer. It has embedded itself into the registry- so it is not on the hard drive. He has Windows 2000 Pro, and the Microsoft Messenger has been disabled. We have also tried Spybot, etc. Nothing works...
