A pop-up window is a type of window that opens without the user selecting “New Window” from a program’s File menu. Pop-up windows are often generated by websites that include pop-up advertisements. These ads are produced with JavaScript code that is inserted into the HTML of a Web page. They typically appear when a user visits a page or closes a window. Some pop-up ads show up in front of the main window, while others show up behind the main browser window. Ads that appear behind open windows are also called “pop-under” ads.
Regardless of where pop-up advertisements appear on your screen, they can be pretty annoying. Fortunately, browser developers have realized this and most Web browsers now include an option to block pop-up windows. If you are noticing pop-up windows appear on your computer when your browser is not open, you may have an adware program running on your computer. The best solution to this problem is to run an anti-spyware program that will locate and remove the malware from your system.
Pop-up ads are forms of online advertising on the world wide web intended to attract web traffic or capture email addresses. Pop-ups are generally new web browser windows to display advertisements.
