The ILOVEYOU worm, also known as VBS/Loveletter and Love Bug worm is considered the world's most damaging computer worm yet. It is written in VBScript by a Filipino college student. It began in the Philippines on May 4, 2000, and spread across the world in one day, infecting 10 percent of all computers connected to the Internet and causing about $5.5 billion in damage. Most large corporations, including the Pentagon, CIA, and the British Parliament shut down their e-mail systems to get rid of the worm. Link
