Errr... I don't see what's the mistery here.... TribalFusion if the ad provider I use on msgplus.net. They are the one who display the banner on top of the page as well as the popup.
TribalFusion doesn't try to connect on your computer 5,000 times, they just display a banner on my site, there's no more interaction than that. As a side note, I would suggest you to be a little less paranoid and stop monitoring this kind of things, i's not worth the tiem you put in it
