The CodeRed worm, discovered in 2001, quickly spread to immense proportions, clogging the Internet with its many requests and bad Engrish.
One thing I didn't mention - the Worm only defaces the website if the language is set to US English, and it reverts the defacement after a week. Also, if the file C:\notworm exists on a PC infected by CodeRed, the worm enters a non-stop period of sleep.
