Today I woke up and find out, two of my sites are showing a pop-under advertisments. I tracked it with http://tools.pingdom.com and find the javascript which is causing it. banners?tid=SWTMPOP&tagid=2
and this is where it leads me to, http://clktag.com/adServe/banners?tid=SWTMPOP&tagid=2 im not using RevenueHits on my site
How can I find out where it is and how to get rid of it.
