What is a Trojan virus?


A Trojan virus, also known as a Trojan horse, is one of the most commonly used and dangerous types of cyber attacks today. It is named after the famous Trojan horse from Greek mythology because it infiltrates systems without the user’s knowledge and remains dormant until activated. In this article, we will answer the question “What is a Trojan virus?” in detail.

A Trojan virus operates differently compared to other malware. Once it infiltrates a system, it does not immediately activate like other malicious software. Its activities upon entering a computer are unpredictable. It can become active right away or remain dormant for years. This is why it is associated with the Trojan horse myth. Source

How to Remove a Trojan Virus?

There are two different types of this virus. The first type involves hackers embedding a Trojan into a popular program, which is then applied by users unknowingly. When users install the seemingly safe program, they unintentionally invite the Trojan virus into their computers. The second type involves deceptive techniques to trick users. It deceives users by imitating the icons of popular applications or games, persuading them to download and install the malware.

Both methods are commonly preferred by malicious individuals. However, it is important to note that this virus should be taken seriously as it can cause significant damage to systems. In some cases, it can even cause financial and personal harm by compromising personal information. So, what can be done to protect against this threat? What are the ways to protect against Trojan viruses? Here are the details…

The most important way to protect against the Trojan virus threat is to use antivirus programs. You can refer to our article titled ‘What is Antivirus?‘ where we provide detailed information in this field. With the numerous antivirus programs available today, it is possible to protect against these malicious software. When antivirus software is downloaded and activated on computers, it not only prevents new infiltration attempts but also detects and removes existing Trojan viruses in the system.

Trojan viruses pose a high threat not only in personal internet usage but also in public WiFi networks. Internet provided in parks, cafes, and hotels is often presented with good intentions but carries many risks. This is because the security measures of these networks are generally lax. Therefore, caution is advised when connecting to an unknown network.
