2Welchia was and continues to be the most unusual worm in the history of the Internet, since it was originally developed not for harm, but, on the contrary, for help. It is noteworthy that with the help of Welchia it was supposed to detect such a virus program as Blaster. However, the worm behaved extremely unpredictably - it infected all computers, killed the virus, and then destroyed itself.
3And here is the most dangerous virus Blaster, which was not so terrible at all, just the media paid a lot of attention to its existence in its time. Created a worm 18-year-old boy Jeffrey Lee Parson, who managed to find a gap in vindousovskoy (Windows XP) protection. The worm wrote a funny phrase on the screen: “Billy, how is it possible, stop making money, better modify your software”. For such a mockery of Bill Gates, the court sentenced Jeffrey to one and a half years of imprisonment.
four.Slammer (“The Prison”) is a super-fast-spread computer worm that managed to infect 75 thousand computers in some ten minutes. It is noteworthy that the creator of the virus crammed into the code only about two hundred bytes, nothing more.

7. Elc Cloner.This old (1982 writing) virus is the work of the Elk Cloner, only a high school student. Elc Cloner infected computers through floppy disks - after every fiftieth of the download, the virus forced the screen to show a rhyme written by its talented young creator.

9. ILoveYou.This email virus is quite original. And in view of the fact that it caused enormous damage to millions of computers, ILoveYou is called the most dangerous virus in the history of the Internet, because since 2000 it has managed to infect more than 50 million computers in just nine days, and also forced the Pentagon and the CIA to close their computers.
