A description of how Conficker spreads

Conficker (also known as Downup, Downadup and Kido) is a computer worm that first showed up in October 2008. It targeted the Microsoft Windows operating system.[1][2][3] It is not known where the name "conficker" came from. "Internet experts" have guessed that the name comes from a mix between two different words: "configure" and "ficken", the German word for "fuck".[4]

Conficker was believed to be the worst computer worm since the SQL slammer worm in 2003.[5] It was estimated 15 million computers were infected with Conficker.[6][7] The virus was supposed to get worse on April 1, 2009, which caused many people to worry about it. However there were no bad effects.[8]

On 13 February 2009, Microsoft offered a $250,000 USD reward for help with finding and arresting the people who created the computer worm.[9][10][11][12][13]
