Worms, viruses, Trojan horses, logic bombs, and spam are types of cybervandalism. Define each and ...

Cybervandalism ranges from sending destructive viruses and worms to hacker attacks designed to destroy important computer networks. A computer virus is one type of malicious software program that disrupts or destroys existing programs and networks, causing them to perform the task for which the virus was designed. Computer worms are similar to viruses but use computer networks or the Internet to self-replicate and send themselves to other users, generally via e-mail, without the aid of the operator. A Trojan horse looks like a benign application but contains illicit codes that can damage the system operations. A logic bomb is a program that is secretly attached to a computer system, monitors the network's work output, and waits for a particular signal such as a date to appear.
