'Your device has been infected with 27 viruses' Pop-Ups

The 'Your device has been infected with 27 viruses' pop-ups are deceptive messages that try to trick users into thinking that their devices have been infected by multiple threatening viruses. A large portion of these pop-ups appear to target iPhone and iPad users, but it is likely that their creators also have created fake pages used to target Windows and Android users as well.

The message targeted at iOS users, in particular, are cleverly designed to mimic the design of legitimate iOS menus and alerts, therefore leaving users under the impression that the alert is legitimate. However, the 'Your device has been infected with 27 viruses' pop-ups are trying to lure victims into downloading a piece of software from a non-trustworthy source. The application they download poses as a security tool, but it may end up being adware, a Potentially Unwanted Program or a more harmful application.

You should never trust random browser alerts telling you about active viruses on your system – these are usually used to involve you in scams or to get you to download shady software. The 'Your device has been infected with 27 viruses' pop-ups are fake, and you should ignore their contents entirely.
