you are an idiot virus

The "You Are An Idiot" virus (officially known as Trojan.JS.NoBrain) is an iconic joke program malware from the early 2000s. Although it did not destroy files or steal data, its operation was extremely intrusive and could lead the system to a critical freeze. The main purpose of the virus was to psychologically irritate the user and demonstrate vulnerabilities in browsers of the time (mainly Internet Explorer). After activation, a black and white, pulsating animation of three smiling characters appeared on the screen, accompanied by a looped, joyful singing: "You are an idiot! Ha-ha-ha-ha-ha!" The real maliciousness of the virus was revealed when trying to close the window. Using the "X" button or the Alt+F4 shortcut launched a script that opened several new, smaller windows that "escaped" the mouse cursor across the desktop. Each subsequent attempt at closing intensified this effect, which led to an avalanche of processes. As a result, the RAM and processor were completely overloaded (so-called fork bomb), which forced a hard restart of the computer. Today, the virus has cult status on the Internet. Modern browsers, thanks to pop-up window blockers and better JavaScript management, are resistant to it, but in its heyday it was one of the most recognizable jokes that could effectively paralyze work on Windows 95, 98 or XP systems.
