If you are using Mozilla Firefox, there is an add-in (under 'Tools' and 'Adblock' that will do the trick. Unfortunately you have to update it for different websites you use frequently, but it is very quick and
If you are using Internet explorer the option is again under 'Tools' and 'Pop-up Blocker'.
OOH! I had this and it was getting worse and worse. Yesterday it was up to 15 in a couple of minutes. CiD adware and they still got through the pop-up blocker. I'm with aol and I contacted their interactive helpline and they sorted it-- yesterday, as it happens. PC was infected with spyware virus. Had to go to control panel, add/remove programs, and then unistall the messenger application. Sorted. Try it.
Ah yes! I was going to add that you might have to run it past an addicted DD first!! Which is worse? Her or the pop-ups?! OR, you could uninstall it, then re-install it. Perhaps that would stem the flow for the time being.
