The Conflicker Worm, which is also known as Downup, Downadup, or Kido was first appeared on October 2008.  The worm targets systems
which run the Microsoft Windows operating system (e.g. Windows 2000/2003, Windows XP, Windows Vista and Windows 2008). Scientists
believe that Conflicker was able to propagate through the Internet and infect more that 10 millions connected systems. The worm was
programmed to communicate with its Bot servers on the 1st April 2008.
