Why are some computer viruses called trojan horse

Trojan malware takes its name from the classical story of the Trojan horse, because it imitates the technique to infect computers. A Trojan will hide within seemingly harmless programs, or will try to trick you into installing it. Unlike viruses, Trojans do not self-replicate by infecting other files or computers

NOT MY CONTEXT!!

The original Trojian Horse was created in ancient Greece during the Trojian War. The army created a wooden horse that was sent as a gift to Troy. But the horse was full of soldiers ready to fight once they entered Troy's gates.

A Trojian horse virus works in a similar manner. It is a virus disguised as some thing you want (i.e. a video game), but when you download it to your computer the virus is realeased and does what is was coded to do.
