“U.Z.A. Operating System” Wallpaper screenshot“U.Z.A. Operating System” Wallpaper a symtpom of a worm, U.Z.A. O/S Eliminator. U.Z.A. O/S Eliminator is a worm that uses the autorun feature in windows to replicate itself on different computers via removable drives.

U.Z.A. O/S Eliminator changes your desktop wallpaper to a black graphic with white lettering reading “U.Z.A. Operating System,” and adds an icon next to the clock in the system tray. U.Z.A. O/S Eliminator blocks your access to task manager and adds what looks like a folder labeled My_Personal_Data to the root of your USB/removable drive. This folder is actually an executable file that simply hides behind a folder icon. With the autorun feature activated on your system, U.Z.A. O/S Eliminator then propagates itself into every computer it is attached to. Pretty nasty, huh?
