Probelm is still there. I deleted Limewire from my computer and then put spybot in there and cleaned out my computer. I have then reinstalled Limewire from the official site---just as I had the first time---and I am still have pop-unders. No where near as many as at first but they are still there and they weren't there before I downloaded Limewire. There is something happening during the download of Limewire that is letting this get into my computer. And the main page clearly comments on no Adware.

I guess I'll just have to remove Limewire from my computer and do another cleaning and not use it again. It's a shame as Limewire seems to be quite good from what little I have used it but the ads are intolerable.
