What is a Pop-Up?
A Pop-Up Window is a web browser window that is smaller than standard windows and without some of the standard features such as tool bars or status bars. Many legitimate advertisers on the Internet use windows that pop up in the middle of your screen to display a message. They might also open when you click a link or button on a Web site, and they might open either over or under the window you wish to view. Some pop-ups are helpful. For example, if you click an image to see a larger version, it might open in a pop-up window. Unfortunately, some pop-up windows can contain inappropriate content or can be a way for you to accidentally download dangerous software (called spyware or adware) onto your computer.
