The pop-unders are believed to be less intrusive and thus make for better overall advertising results than the pop-ups according to some behavioral studies. The whole reasoning behind the development of pop-under adware is that as the pop-ups ads became something more and more common many users developed the useful habit to close down the pop-ups as soon as they begin to appear, thus avoiding even a look at them. This is an especially tricky practice as it makes it that much harder to determine the exact website that caused the pop-under adware to appear. Unlike pop-ups, the pop-under will not immediately disrupt and alert the user of its existence, but only when the “covering” windows get closed down.

The pop-under adware opens a new window under the currently active browser windows. In addition to the regular adware, there is what is called pop-under alternate adware. If you notice the symptoms of Pop-up Adware inside your browser, you ought to quickly find and remove the source of those symptoms.
