The malware that appears as a harmless object but attacks its victims at the slightest opportunity is called a "Trojan horse". It is named after the wooden horse that was used by the Greeks to enter the city of Troy in ancient mythology. Trojan horses are malicious software programs that are disguised as legitimate programs, such as games or utility software. When a victim downloads or installs the Trojan horse, it can carry out a variety of attacks, such as stealing personal information, modifying or deleting files, and giving hackers unauthorized access to the victim's computer. Unlike worms, which can spread on their own, Trojan horses require the victim to execute them. Macro viruses are viruses that infect documents, and logic bombs are programs that are designed to execute a malicious action at a specific time or under certain conditions.
