Rob -- just to clarify (because my attempt at explanation was pretty ham-fisted), I didn't mean spyware. I actually just meant the pop-up ads themselves. These are just typical pop-ups like you would get at any site, just that they are scripted in a way that refers to general system info on your computer. If you see one of thses ads, it does not mean that anything has been secretly installed on your computer, nor does it mean that any private info is being sent from your computer. They're more like Mad Libs. Again, I wish I could find something to explain it better...

(by the way, my coding is the previous post is incorrect, but it gives you the general idea...)
