A Trojan Horse, also known as Trojan, is malicious software or code that controls your computer system. Upfront, it looks legitimate, but it is created to cause damage, steal, or commonly inject a degree of harmful action on your network or data.
It serves as a bona fide file or an application to deceive you. It generally tricks you into loading and implementing the malware on your computer system or device. Once it is installed, the Trojan performs the action it has been created for.
What is the Trojan Horse?
The Trojan Horse is often referred to as a virus; however, the term is a misnomer. Viruses have the ability to replicate themselves. However, a Trojan Horse cannot. The user needs to execute the Trojan Horse, and this is why the virus and the malware are used as interchangeable terms.
Whether you wish to call it the Trojan malware or the Trojan virus, the choice is yours. However, it is important to know how it works and what you can do to keep your devices and computer systems safe.

When you implement the program, this malware spreads to the other files in the computer and damages it. The extent of this damage varies as the Trojan Horse has been created to do different things, and most of them are those you wish are not present on your device.
