A computer virus is a form of malware when it is executed, replicates by adding copies of itself into other computer programs, data files, or the boot sector of the hard drive; when this replication achieves, the artificial areas are then believed to be "infected". Viruses frequently act out as some type of harmful action on infected hosts, also as stealing hard disk space or CPU time, entering private information, humiliating data, showing supporting or amusing messages on the user's screen, spamming their contacts, or logging their keystrokes. On the other hand, not all viruses hold a negative payload or try to conceal themselves - the major feature of viruses is that they are self-replicating computer programs which install themselves without the user's permission.

The Trojan Horse is a story from the Trojan War about the subterfuge that the Greeks would enter the city of Troy and stop the disagreement. In the canonical version, after having 10 fruitless years, the Greeks created a huge wooden horse, and hid a chosen amount of foreced men inside. The Greeks acted like they were sailing away, and the Trojans pulled the horse into their city as a victory trophy. That night the Greek force snuck out of the horse and opened the gates for the rest of the Greek army, which had sailed back under cover of night. The Greeks entered and damaged the city of Troy, determinedly finishing the war. Metaphorically a "Trojan Horse" has come to imply any trick or stratagem that causes a target to provoke an enemy into a tightly protected space. It is also connected with "malware" computer programs presented as useful or harmless to tempt the user to install and use them.

Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, while viruses almost always corrupt or modify files on a targeted computer.
