Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Happy99 is a computer worm for Windows. It first appeared in mid-January 1999, spreading through email and usenet. The worm installs itself and runs in the background of a victim's machine, without their knowledge. It is generally considered the first virus to propagate by email, and has served as a template for the creation of other self-propagating viruses. Happy99 has spread on multiple continents, including North America, Europe, and Asia. Happy99 was described by Paul Oldfield as "the first virus to spread rapidly by email."show more
