Pop-ups are annoyances that are meant to make you want to visit the websites they represent or to make you accidentally click on them so that you are taken to those websites. On a pop-up screen, there may be an advertisement or a game that offers a prize if you win. Often, a website will have pop-ups that show full nudity or partial nudity, and many times, you’ll find out that on the other end of the pop-up is a virus or some other form of malicious software that will infect your computer and cause more pop-ups to appear or destroy your system. To avoid pop-ups, you’ll have to adjust the Pop-up Blocker on your Web browser’s Internet options.
