trojan

word

Definition

A 'trojan' is a type of computer program that looks harmless but actually harms your computer, often by stealing information. It can also refer to the ancient Greek myth of the 'Trojan Horse', used to trick and invade the city of Troy.

Usage & Nuances

Most commonly, 'trojan' refers to malware ('trojan virus', 'trojan horse') in technology contexts; rarely used in daily conversation unless discussing computers or ancient history. Don't confuse with the noun 'Trojan' as a person from Troy. In computers, a 'trojan' does not replicate itself (unlike a virus).
