A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. The original may modify the copies or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable medium. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. A Trojan horse is a form of malware that presents itself as a legitimate program. In contrast to viruses, Trojan horses do not insert their code into other computer files. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms. Furthermore, some sources use an alternative terminology in which a virus is any form of self-replicating malware.

Almost all computer viruses originate from the companies that sell anti-virus software. This has always been the case. These people make millions from the trade. Its the mafia of the internet and computing. We are forever paying protection money.

Yes, they are made by people. As for why, you'll have to ask them, but presumably it's because of the notoriety it involves.
Note that a lot of viruses are not made by expert programmers, but "script kiddies" who use readily-available toolkits.
