A trojan horse is a type of harmful code or program that, when carried out, duplicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the impacted areas are then said to be contaminated with a virus.
Infections typically spread out by developing a copy of themselves on a user's computer without the user's understanding or permission. Oftentimes, infections will be spread out by e-mail accessories or by files shared on peer-to-peer networks. As soon as an infection has actually contaminated a computer, it can infect other computer systems on the exact same network.

For example, an infection may delete files, fill a hard disk drive with useless data, or corrupt system files. https://thefishandthechip.com/?p=628 In many cases, a virus may even show a message or image that is developed to scare the user.
