How do I stop pop-up and pop-under Internet ads?

Advertisements on the Internet can be invasive. To get your attention, they are sometimes programmed to pop up in front of your current browser window, obscuring the content you want to see. Even worse, sometimes they will "pop under" your window, so that you don't see them until you minimize your browser. These ads are not only annoying, but it can interfere with your computer's performance. The good news is, most modern web browsers provide options for blocking these types of ads.
