Disguised as an Operating System, this virus affected millions of PCs in late 2007 to early 2008. It used constant annoying pop-ups to numb the user to PC warnings. After a month of hitting "Allow" or "OK" -regardless of the content of the pop-up message- a user would inadvertently allow their PCs to install more "features" and spyware (disguised as UPDATES) to their PCs until the slowed down to a snail's pace. This virus also sent the PC "Shut Down" function into obscurity, forcing more users to contribute to botnets by leaving the PC in sleep mode and the botnet code in RAM.
The only known removal method of this virus is a complete re-install of a competing OS or an earlier Microsoft OS.
