Pop-ups are those annoying advertisements that - as the name says - pop up on your monitor as you surf the Internet. Their main purpose is to attract visitors to advertisers’ web sites or to collect e-mail addresses.

These pop-ups are usually caused by something called Javascript, which is a simple programming language built into the web page you’re visiting.

Some pop-ups are useful. Sometimes a user clicks a link on the Web page and a small window will open asking a user to fill in information or giving a user more information. Music sites often use pop-ups to play tunes in a specialized player window. This can be a completely legitimate use of pop-ups and is quite different from the pop-up advertisements that appear unbidden.

JavaScript can control the size of the window and the elements displayed. The status bar or the menus can be hidden, making it impossible to navigate away from the pop-up. Your only options are to close the window using the ‘x’ box in the top right corner or to click on the ad and be taken to the advertiser’s web site. Annoying, huh?

Some of these pop-ups can cause other problems as well. They may be poorly programmed, or they may be intentionally malicious and can cause many windows to be opened. And when you close one, several more open to replace it. When this happens, the only way to get rid of them is to close the browser.

A relatively new kind of pop-up is created using Flash and can be programmed to follow your mouse or to float on the screen as you scroll the window.

One of the more notorious uses of pop-ups is in adware, which often opens pop-ups related to the web pages you’re looking at, even if it’s not from that website. This adware is supported by advertising, which is why it uses these pop-ups to get your attention. It usually comes along with some other program, which may actually be useful, and gets installed at the same time. If you don’t read the license agreement closely when you install it, you might miss the fact that this is going to happen even though they tell you (although it’s usually hidden somewhere in the middle of the agreement, where most people never see it).

Another form of pop-up is called the pop-under. It opens a window behind the main window and you won’t see it until you close your main browser window. These types are less annoying, but can still be a pain.

The main problem with pop-ups is the nuisance they cause, and almost every web browser has some kind of pop-up killer included these days.

You can also get specialized pop-up killer software that will catch most of the pop-ups that the browsers miss, giving you an almost 100% pop-up free internet experience.
