While doing the paid emails at Cash Desks, I ran across several bad ones. In particular, the Insurancesite email:
http://cashdesks.com/scripts/runner.php?EA...803140620023524
has an iframe for Pay-Ads disguised as a banner
(code below)<script>ads_id="2599";b=window.document;b.write('<iframe src="http://www.pay-ads.com/ads.php?usr='+ads_id+'" width=480"'+'" height=60"'+'" frameborder="0" scrolling="no">Your browser does not support IFRAME</iframe>');</script>
This Pay-Ads "banner" then proceeds to run numerous autosearches through over a dozen hidden iframes and javascript commands including Luxemil, findsprint.info, we-ads, dxptp, i-e-search.com, upperhits.com, isearchmoney.com, cb-search.com, nbcsearch.com, feedwithus.com, mygole.com, and adtris.com.
This is the fourth paid email today at CD which has crashed my browser. I finally got annoyed enough to take 30 mins and go through the code for these pages. You may want to carefully check all the email ads you have running. I don't notice this problem yesterday or the day before so someone at these search engines added the bad stuff to their pages today (primarily the SEs run by the same people as insurancesite).
Good Luck.
