Malware

Viruses

A virus is a piece of malware that is designed to spread across a network. The virus will remain dormant on a computer until it is executed, then it will spread to other programs on the computer and potentially to other devices.

Trojan Horse

In Greek Mythology the Greeks used a large wooden horse to infiltrate the walls of the city of Troy. During the war the Greeks gifted a huge wooden horse to the Trojans as a sign of peace and pretended to retreat. The Trojans accepted the gift and brought it in to passed the walls to the centre of the city. During the night, when the Trojans were asleep, Greek Soldiers crept out of the horse and took over the city.
