Detailed explanation-1: -When hackers create fake website pop-up ads to try and infect your device with malware, it’s called malvertising. Some malicious pop-up ads are easy to avoid. You don’t click the link or call the phone number. But thanks to the science of steganography, hackers could embed malicious code directly into the pop-up ad.
Detailed explanation-2: -Adware can automatically get downloaded to your system while browsing any website and can be viewed through pop-up windows or through a bar that appears on a computer screen automatically.
Detailed explanation-3: -If you see a pop-up that looks suspicious, don’t click on it. Hackers can make pop-ups look like they’re from a legitimate website, but clicking on them can still lead to your computer getting infected with malware. Instead, try to close the pop-up by clicking the ‘X’ in the corner of the window.
Detailed explanation-4: -If you’re seeing the pop-up ads on every website you visit, or if your browser’s homepage has been changed unexpectedly, it’s possible your browser has been infected by a type of malware known as adware. Adware injects ads into web pages in such a way that they can’t be blocked.
