What is a Trojan ?
Computer Trojans or Trojan horses is a kind of virus that is characterized by cheating users masquerading programs or legitimate and benign files (photos, music files, files of mail, etc.), in order to infect and cause damage. The main objective of a computer Trojan is to create a backdoor that access remote management of the attacker not authorized, in order to steal personal and confidential information.
The term of Trojan comes from the history of the “Trojan horse” mentioned in the book “The Odyssey” by “Homer” and is used to deceive, surprise and cause damage. The Trojans are designed to enable an attacker to access a system remotely and perform different actions “without asking permission”. The actions that the attacker can perform depend on the privileges of the user who is being attacked and the characteristics of the Trojan.
In the same way that the mythological Trojan horse appeared to be a gift but contained Greek soldiers who dominated the city of Troy, the Trojan horses of today are computer programs that appear to be useful software but threatening the safety and cause much damage. A recent Trojan appeared as a message of an email that includes attachments that appeared to be Microsoft security updates, but that turned out to be viruses that attempted to disable antivirus software and firewall.

The Trojans are made up of two files: a client that is sending the orders and a server that receives the client orders, runs them and returns results.
A Trojan can be running on a computer for months unless the user perceives nothing. This makes it difficult detection and elimination of manually. Some patterns to identify them are: an unknown program is running when you start the computer, you create or delete files automatically, the computer is running slower than normal, errors in the operating system.
Trojans can also be included in software that you download for free. Never download software from a source that you trust not. Always download the updates and patches from Microsoft to Microsoft Windows Update or Microsoft Office Update sites.
