Mo21.biz is a fake website usually displayed on computers, phones or tablets that have accepted to send advertised notifications from the Mo21.biz site.

Mo21.biz is a website set up by cybercriminals to display unwanted ads. Ads through Mo21.biz are displayed via push notification functionality in your web browser.

If you have accepted ads from Mo21.biz, these ads are displayed in the bottom right corner in Windows or through the web browsers such as Google Chrome, Firefox, Microsoft Edge and Safari.

If the Mo21.biz website is displayed in your web browser, then you have been redirected via a rogue ad network to the Mo21.biz website. In most cases, users do not visit the Mo21.biz directly, but a redirection to Mo21.biz is created through an ad network.

The Mo21.biz tries to convince users to accept notifications after the referral. The message displayed to mislead users usually contains texts like “Click here to continue” or “Verify that you are not a robot”. They are misleading messages that trick you into clicking on the Allow button that appears in the web browser at the same time. In reality, you are not accepting a referral but accepting to allow push notifications to be sent to your computer, phone or tablet.

You must remove the Mo21.biz notifications from your computer. The notices sent through Mo21.biz redirect the web browser to various dangerous ads that might infect your computer.

Most of the ads sent through Mo21.biz are based on misleading texts. However, some ads promote adware programs and malware programs that may further infect your computer with malware.

If you continuously see ads that redirect to Mo21.biz, I recommend checking your computer for malware, more specifically adware. Adware programs are known to continually display ads to trick users like you into clicking on them. Therefore, check your computer for adware immediately and remove adware programs from your computer as soon as possible. Removing adware can also instantly stop Mo21.biz ads from appearing on your computer.

Make sure to remove the Mo21.biz notification permissions first from your web browser settings.
