The basic concept of a pop-up is a window that appears out of nowhere as you are viewing content on the web. Generally, there are two types of pop-ups. The first type appears when clicking on something on the web. The second type appears at random. The second type is usually the most aggravating. More often than not, these busy windows exclusively display ads for content the user has no interest in. Sometimes the advertisements are offensive or even worse, adult oriented. A pop-up could also be a malicious program in disguise such as a Trojan horse. Please watch the video below to see how to stop pop-ups on a Windows based PC.
