Ilott is a Trojan virus that exists at present. Trojan virus is called "Trojan horse" because it originated from the Greek myth "Trojan horse massacre". In ancient Greece, an army besieged Troy, which could not be captured for a long time. So someone presented a plan to make a two-foot-high wooden horse, pretending to be a fighting horse god, and let the soldiers hide in the huge wooden horse. The big troops pretended to retreat and left the Trojan horse at the gates of Troy. After learning the news of the clearance, the city dragged the "Trojan Horse" into the city as a strange trophy, and the whole city drank and reveled. In the middle of the night, the soldiers and civilians in the city fell asleep. The soldiers hiding in the wooden horse opened the secret door, swam down the rope, opened the gate and set fire everywhere. Ambushments swarmed outside the city, and troops were inside the city, burning and looting Troy. Later generations called this big Trojan horse "Trojan horse". Now the hacker program borrows its name, which means "once infiltrated, there will be endless troubles." A complete Trojan horse program generally consists of two parts: a server program and a controller program. "Trojan Horse" refers to the server program with Trojan Horse installed. If a server program is installed on your computer, people with controller programs can control your computer and do whatever they want through the network. At this time, all kinds of files and programs on your computer, as well as the account and password used on your computer are unsafe.
