How to Clear Pop Up's on My Computer
A pop-up is a window that opens on your screen as you are viewing content on a website. Usually these pop-ups appear out of nowhere. A main reason you have a pop-up on your screen is that you have clicked a link on a web page. The pop-ups are usually a form of advertising. Some popups might display fake warnings that your computer is infected with a virus, tricking you into clicking a link to purchase their software. You can clear pop-ups by turning on the pop-up blocker built into the web browser you use.
