Replying to weird freakin problem

every time i'm on newschoolers i get a porn popup and it happens like every 10 mins. it's a seperate window that pops up. this thing only comes up on newschoolers, no other site on the web. i've cleared my cache, ran spybot and ad-aware and i ran hijack this and it's still there. but only with newschoolers!! what is this?
