If you don’t know what the “adult player” app is then you have nothing to worry about. If you do then you just might get into some trouble.
Adult Play is a pornographic app on Android that snaps secret pictures of its users. Then it blocks their phones and asks for a ransom in order for the phone to be used again.
Such “ransomware” apps
are similar to viruses that attack computers. However these apps bombard the users with ads or take unfortunate photos of them and then ask them for a certain amount of money.
