How Did I Get Infected With YAAI Trojan Virus?

This Trojan typically enters systems when users visit a specific website associated with the “You Are An Idiot” prank. The site launches multiple bouncing browser windows with looping audio and repetitive taunts. These windows keep duplicating, eventually consuming system resources until the computer slows to a crawl or freezes entirely. In many cases, users are forced to reboot or use Task Manager to regain control.

What the YAAI Trojan Virus Does to Your System

While YAAI doesn’t steal data or encrypt files, it’s designed for maximum disruption. The virus can create system entries that allow it to reopen or re-trigger after reboot. It may drop files into obscure folders like AppData or Temp and create startup or scheduled task entries to persist in the background. These tricks make it harder to remove unless all components are eliminated.
