experiencing a page redirect on forum list page

[Grimstitch]

hi, just wanted to report a problem that i'm having whenever i load the page http://www.conceptart.org/forums/

the first time i access the page in any given day, i get a redirect warning popup that seems to be coming from some image or other, and a (porn) site called live jasmin appears in my browser history. it may be that an invisible frame has opened because it doesn't matter whether i click yes or no, still creates a link in my history, but that does not happen if i ctrl alt delete instead. also, it only happens in IE so far so an obvious solution is just to use another browser, but thought i would let you guys know about it anyway. happening to anyone else?

took a pic with my phone, since didn't want to click anything on the screen - can upload it in a moment

We've had this reported before but on the home page. Hopefully the soon to be upgrade will sort it out. I don't see it when I log on - it might me a good idea to run some malware programs on your computer in the mean time.
