Google Chrome occasionally displays a pop-up window in front of your browser when you visit websites. Typically, it's an advertisement aiming to persuade you to buy something. What should you do to prevent this from occurring?

Pop-up windows are annoying, but they aren't always a sign that your computer is infected. The pop-up blocker in Chrome can be enabled to stop them. Antivirus and anti-malware programs don't deal with pop-ups unless they are linked to malware. The majority of pop-ups are not associated with malware, they are just coded into the website. Pop-ups cannot be blocked by a firewall, either.
