Not a direct answer, but something better than an ad-blocker: Mozilla browser - free, stable and very good. Has both a built in popup stopper and a built in ad blocker.

If you use Mozilla, and see an ad, just right click on it and tell it to block images from that server: thus you miss out on doubleclick and similar and after a couple of weeks end up with an impressive list of blocked ad servers. It is even possible to download these lists from the net and be blocked immediately.
