A trojan horse is a type of malicious code or program that, when performed, reproduces itself by customizing other computer programs and placing its own code. When this duplication prospers, the impacted locations are then said to be infected with a virus.
Viruses frequently spread out by producing a copy of themselves on a user's computer without the user's knowledge or permission. Oftentimes, viruses will be spread out by email attachments or by files shared on peer-to-peer networks. Once a virus has actually infected a computer, it can infect other computers on the same network.
Some viruses are programmed to spread themselves in a method that might trigger serious damage to a computer system. An infection might erase files, fill a tough drive with useless information, or corrupt system files. In many cases, an infection may even show a message or image that is developed to frighten the user.
