What is a pop-up?

A pop-up is a small window that appears over other windows on your computer screen. It is typically used to display advertisements, alerts, or other information. Pop-ups can be triggered by a variety of events, such as visiting a website, clicking a link, or hovering over an element on a web page.

Some pop-ups are designed to be helpful, while others can be annoying or even malicious. For example, some pop-ups may provide you with information about a special offer or alert you to a security risk. Others may try to trick you into downloading malware or signing up for a subscription service.

You can control the behavior of pop-ups in your web browser settings. Most browsers allow you to block all pop-ups, or to only allow pop-ups from specific websites. You can also disable pop-ups for specific types of content, such as ads or social media widgets.

If you see a pop-up that you don't want, you can usually close it by clicking on the "X" button in the corner of the window. You can also press the "Alt+F4" keys to close all open windows.

If you are concerned that a pop-up may be malicious, you can scan your computer for malware using a security scanner. You can also report malicious pop-ups to your browser or security software provider.
