Is a Trojan horse a special virus?

Answer 1

A Trojan is a worm that is usually disguised as a desirable download that when executed drops other worms on your computer. Hence the name Trojan horse. A Trojan is not technically a virus because it cannot reproduce itself.

Answer 2

A Trojan horse isn’t a virus, but it’s a type of malware. Unlike viruses, Trojans don’t replicate themselves. Instead, they disguise as legitimate software to trick users into installing them, giving attackers access to systems or data.
