Trojan Viruses: History, Dangers, Types, and How to Prevent Them!

Trojan viruses are one type of computer virus that is well known to the public because it exists to infect many computers. As with viruses in general, this Trojan horse can damage the computer being attacked.

The physical form of this virus is like the software we know. Looks harmless, but when activated it can cause damage to the computer system or network.

Investigate several trusted sources, giving this Trojan a unique name. How come? Because the name Trojan Horse refers to a historical event about the collapse of the Trojan Fortress which is known to be impenetrable to the enemy.

Once upon a time the Spartans used a strategy of infiltrating with a large horse statue and when they were about to enter the city at night they came out and moved. Not long after that, the Trojan Kingdom fell to the enemy.

Such a concept was adapted to the Trojan Horse virus which is known to be able to penetrate computer defenses. Yes, although it does not immediately attack, this virus deliberately stays on the computer patiently. And when the computer’s defenses were off guard, this virus immediately attacked fiercely.

Trojan Horse Virus Danger

As I mentioned above, this virus is not like any other computer virus. Where other viruses immediately appear with the appearance of strange files or other things. While the Trojan Horse Virus is like an invisible ghost that moves silently.

Trojan Horse is usually made by someone from a distance in the form of a program like in general (.EXE or .COM). The movement of this Trojan can be controlled remotely for certain purposes.

There are many purposes, friend, from stealing important data such as passwords, information, credit card data, or others.

This Trojan virus usually does damage by deleting files randomly on your computer. Before being infiltrated into a computer, a cracker or attacker first breaks into the system (usually via the internet) and then inserts files with unknown sources.

One of the best antivirus for Windows OS is Windows Defender. Please read how to activate Windows Defender (Windows 7, 8, and 10).

Trojan Horse Virus Types

Until now, there have been quite a number of Trojan viruses that have been identified. Before I explain about how to prevent it, it’s good for techno friends to know the types first. Here is the full review!

1. Data Sending Trojan

This type of Trojan was created to retrieve important data such as passwords, account data, files, credit card numbers, and others. Data retrieval is usually done by searching the entire computer.

The working system is actually simple, namely by recording the buttons you press when entering important data such as passwords. After recording the button, it is sent to the hacker or the maker of the Data Sendring Trojan.

2. RAT (Remote Access Trojan)

This type of virus gives attackers access to take full control of computers that have been infiltrated. Usually this RAT is hidden in small programs or games so that you don’t raise the slightest suspicion. This type of trojan virus is really horrifying.

3. Proxy Trojan

This type of virus is specifically designed to be able to infiltrate a computer and then make it a Proxy Server. Once that happens, security will become easy and provide opportunities to continue exploiting the compromised computer.

The worst impact is when another network is attacked but uses your friend’s system that has been compromised.

4. Destructive Trojan

This type of Trojan virus has the ability to damage and destroy flees in a computer that has been infiltrated. Even more so if the antivirus is unable to detect the presence of this virus. Of course it’s very troublesome.

5. Dos Dojan (Denial of Service Trojan)

This virus is more focused on damaging computer networks by flooding traffic resulting in your computer down. Usually, by exploiting the limitations of the IP Protocol on a computer.

6. Security Software Disable Trojan

This type of Trojan cannot be sent alone but together with other viruses because it is only as a support. Usually tasked with destroying security in computers such as antivirus, firewall, and others without the user’s knowledge.

How to Prevent Trojan Horse Viruses

Like my promise above, after techno friends know some types of trojan viruses that exist in the world. Next, I want to share about how to prevent this virus.

The existence of this virus is often considered trivial for some people, even though the impact and damage is terrible. For this reason, concrete steps are needed to overcome or at least minimize the impact.

The most important point in preventing Trojan viruses from entering the computer version of is to install an antivirus. Try to keep your antivirus updated so that the features provided can be powerful.

Don’t forget to activate the default Firewall from the OS or even the external Firewall to increase the security of your computer.

Due to the spread of this virus via the internet, it’s good for techno friends to start reducing the habit of downloading pirated software from websites that provide pirated software that are widely available on the internet.

This is because hackers often sneak Trojan horses into pirated applications. If you are already or forced to download pirated software from these websites, just scan it using your antivirus.

And never also disable antivirus, because it could not be detected when a Trojan virus was scanned. But in fact the virus is hiding and when your computer security is weakened. The virus will immediately attack. How awful!

That’s the information I can convey about the Trojan Horse Virus. If this article is useful, do not hesitate to share it with friends or relatives so that they can find out about the ferocity of this virus. That is all and thank you!
