Another new type of virus has been gaining popularity in the past few years, and that is the “… virus” or, put simply, a hoax. Rather than actually writing a virus, a hacker sends an email to every address he has. The email claims to be from some well-known antivirus center and warns of a new virus that is circulating. The email instructs people to delete some file from their computer to get rid of the virus. The file, however, is not really a virus but part of a computer’s system.
