Pop ups are generated by advertisements on websites. Some modern advertisers use annoying techniques like the "forever" cookie, a piece of information stored in your browser, to monitor and track your movements across the Internet, then providing a pop-up advertisement applicable to your consumer profile. These advertisements get annoying, and that is why most modern Web browsers provide pop-up blocking function. To make sure that pop-up blocking works, you also need to clear your browser cookies before enabling the blocker.

- If you continue to experience pop-up advertisements and your web browser's pop-up blocker is enabled, then the advertisements are not coming from your web browser and are likely a part of malicious software installed on your computer. Many of these types of pop-ups are phishing scams to extract your personal information and financial details, some may even be potentially harmful viruses. Use your system's virus scanner to attempt to remove the malicious software. If the virus scanner is unsuccessful you should have your computer looked over by a professional since some malware code can embed itself further into your system than a virus scanner can detect or remove.
