Are Trojans dangerous?

Malware is also a type of computer program designed and developed by humans. Malware is like  software and is designed and developed  by individuals. But the difference between software and malware is in their use. In this case, the malware can be designed to disturb users and damage their systems. But software is designed to meet users' needs, and users can use them to meet their own needs.  Malware is designed to harm users' systems and sometimes even to hack into their systems. It should be noted that there are different types of malware, and among them, we can mention viruses, worms, etc., which in this article we want to tell you about its.

What is a Trojan?

It should be noted that it are the same computer programs designed and produced to destroy and damage systems.  this are called malicious software or malware. This type of malware or malware can attack different parts of the user's computer that are programmed and cause the destruction or theft of data or damage to the system.

It is good to know that the name of this malware is derived from the Trojan horse. Choosing this name for this malware has an interesting philosophy and story. In ancient times in war, the Greeks had chosen a way to defeat the enemy, and through this, they were able to defeat their enemy. In this way, the Greeks, using the method of deception, were able to deceive their enemy and invisibly enter their territory and defeat them. The clever Greeks made a large wooden horse and wanted to give it to their enemy and tell them they intended peace and goodwill. The enemy of the Greeks was also deceived and accepted the gift, which was a large wooden spoon. Inside this large wooden horse were Greek soldiers who, after a large wooden horse entered enemy territory, the cavalry came out of it and fought. The name of that big wooden horse was also Troy. The horse's name, which was Troy, was the same as the enemies of the Greeks.

The reason for choosing this name for this malware is that, like  the Trojan horse built by the Greeks, it invisibly enters the other side's territory by deceiving the other person who intends to do good and destroys it after entering. Like the Greek Trojan horse, this deceive the user, and users think that they are useful software designed and developed by reputable sources, but when they enter the user's system, they destroy it.

As we have said, the Trojan, like the Trojan horse, first introduces itself as a useful and valid software to persuade the user to install after the user is persuaded or deceived by another user and installs it on their system. Kurd, his system will be given to the Trojan and destroyed. A special feature about it is that users cannot see or recognize them. After installation, the Trojans will secretly and gradually engage in sabotage the system. The user can not notice it unless he sees that his system is damaged. In this situation, it can be detected that the malware, which is a type of malware, is damaging the system.

In some cases, hackers may design trojans for purposes and send them to various user systems for espionage to spy on hackers and steal or destroy data. Of course, one feature that Trojans have compared to other malware and viruses is that this are not reproducible and do not multiply.
