This isn’t particularly true to what “type” of site it occurs on.(whcih I assume you guys are pointing at Pron).
This is from another forum that I posted when we where working on this situation, which basiclly turns out there are several versions of that crap out there, and all of them but one pretty mych requires you to do alot of work to rid yourself of it, or a reinstallation of the OS.
So you where asking what someone was doing when they get thi initial popup screen for this, well I just got one, the vista version of it.
I was looking at this page http://linuxappfinder.com/alternatives and click “next” at the bottom right and it popped up instead of going to the next page. no idea as I do not know code of anything, (even conduct, lol) as to why when I clicked the next button on that page made it pop up…just a tidbit of info.
I tried to replicate it and it didn’t pop up the second time there.
here is the link to the oricinal posting of this, hope this helps you out:
