Malware that downloads onto a computer masked as a legitimate program is known to be a trojan horse. The attacker can design the Trojan Malware according to their specified needs, and the trojan horse functions according to the attacker’s needs. The operations may include the following:

• Gaining backdoor access to corporate systems.
• Spying on users’ online activity.
• Stealing sensitive data.

Trojan horses are entirely different from computer viruses because they cannot manifest themselves and need a user to download the application’s server-side for it to work. The user should implement the executable (.exe) files, and a program installs for the Trojan to attack the device system.

Trojans can infect the system through many different platforms or ways, such as downloading malicious applications or Malicious files hidden in banner advertisements, pop-up advertisements, or links on websites.

The Trojan Malware gets activated when the infected system starts working, and the Trojan server will run automatically every time the infected devices get turned on.

Another essential thing about Trojan Malware is that once your computer gets infected, there is a high possibility of infecting other systems.

Types of Trojan Horse:

 Different types of trojan viruses have a variety of function to carry specified by the actor, and here are the most common types of Trojan malware 

Backdoor Trojan: The malicious software programs designed to grant unwanted access for remote attacks are called Backdoor Trojans. 

Banker Trojan: An attack is known as a banker trojan when malware attempts to steal credentials from a financial institution’s client or gain access to their financial information.

Distributed Denial Of Services Trojan (DDOS): It involves sending large amounts of traffic from multiple sources to a service intended to overwhelm it.  

Downloaded Trojan: It is a type of malware which installs itself in the system and waits until an internet connection becomes available.

How to find if Trojan Malware infects your system:

It’s hard for the user to detect that their system is affected by the trojan horse. Sometimes the user may take many months to recognise that their device is infected, but still, many signs indicate the presence of a Trojan, and they are:

To see if your system is affected by Trojan Malware, the best way to recognise the Trojan is to search a device using a Trojan scanner or Malware removal software.

However, there are many signs which indicate the presence of the trojan horse, which include suddenly changing in setting a loss in the computer which had suddenly changed in developing a loss in computer performance or any unusual activities taking place.
