Bug are developed by people who want to trigger harm to others, or who desire to acquire control over another person's computer system. The easiest method to produce an infection is to take some existing code and modify it somewhat. This new code can then be distributed to others, who might unsuspectingly run it by themselves computers. When the infection is running, it can do anything its creator wants it to, including deleting files, stealing information, or sending out spam.
