Why are some computer viruses called Trojan hores?

Some Computer Viruses are called Trojan horses because they disguise themselves as legitimate software to trick users into downloading or installing them. The term is derived from the ancient Greek story of the Trojan War, where Greek soldiers hid inside a deceptive wooden horse to infiltrate the city of Troy. Similarly, Trojan viruses often appear benign but carry malicious code that can harm the user's system or steal information once activated. This deceptive nature makes them particularly dangerous in cybersecurity.
