The "You Are An Idiot" virus, also known as "Idiot Virus" or "YouAreAnIdiot," is a type of malware that infects Android devices. Once installed, the virus displays a full-screen message on the infected device, taunting the user with the phrase "You are an idiot" or similar variations. The message often includes a countdown timer, claiming that the user's device will be wiped or locked unless they complete a series of tasks or pay a ransom.
