Remove Windows Warning Alert

Windows Warning Alert, which shown in your web browser, is a popup alert to try and get you to either buy “Windows Defender” or to call the number 1-833-820-8247. There is a legitimate program called Windows Defender that is installed when Windows is installed; however, if your computer is infected with a computer virus, there was be a fake version, known as randomware, on your computer. If you are just getting popups, and they are due to the websites you are visiting, you can close out, but we recommend that you at least check to see that there aren’t any vulnerabilities in your computer. Below is how the website looks.

It reads “Windows Warning Alert” and “Please call us immediately at” and “Do not ignore this critical alert”. Remember, as this is your own computer, it is important for you to secure your data and act to remove any virus from your computer that may compromise the system.

If the popup continues to come, if could be from a malicious add-in. In Firefox and Chrome, it likely hides as an extension; in Internet Explorer, it likely hides as an Add-on.

Issues like this can be quite frustrating, and it best to remove issues like this to protect your information and data in the computer.
