You know what, I figured out how to turn that off...but am reluctant to do so...I now have my XP firewall on, in addition to my McAfee...

Here is a question...when this happens again, I should be able to do a "control alt delete" and see if my messenger is the one they are using, right? If it's not...if it's just a pop-up add looking like one, it'll just say Internet Explorer...right? Like when I do "Control Alt Delete" right now, one of the applications says "Posting Comment-Microsoft Internet Explorer" for what I'm doing right now...

Does that make sense? I think I should be able to see what is happening when I do Control alt delete...

Yes, doing "ctrl-alt-delete" when a message appears should tell you what application is causing it, whether it's IE or Messenger Service. From the screen picture you posted, I strongly suspect it's Messenger Service. Hopefully the XP firewall will stop them from happening any more.
