Remove U.Z.A. Operating System Wallpaper
. Removal instructions
“U.Z.A. Operating System” Wallpaper is usually a sign that user’s computer is infected with a worm called U.Z.A. O/S Eliminator. The worm uses Windows auto-run feature in order to replicate itself on other computers via removable drives.
Once active, U.Z.A. O/S Eliminator changes default desktop background to black with the following white text: “U.Z.A. Operating System”. It also may add an icon next to the clock in the system tray. However, the most important thing is that U.Z.A. O/S Eliminator creates a folder named My_Personal_Data on user’s removable drive. This folder is actually an executable file. If the auto-run feature is activated, U.Z.A. O/S Eliminator then replicates itself into every computer it is connected to. We strongly recommend you to remove U.Z.A. O/S Eliminator from the system as soon possible. Removal delay can only worsen the situation.
