Internet pop-ups can be an annoying distraction when you are trying to read your favorite website or play an online game. Not only can they be a nuisance, they can also tie up valuable system resources and if the pop-up was not coded properly, it may cause your browser or even your entire computer to freeze. Luckily all of the major Internet browsers offer some form of pop-up blocking. Once you activate the blocking feature, then the Web pages you visit will no longer be allowed to display pop-up windows unless you give them permission. Warnings Writer Bio
