What’s Trojan Malware?

To put it simply, a Trojan (or a Trojan Horse) is a particular sort of software/code that pushes itself to seem harmless and to take control over a user’s device. A Trojan is capable of concealing data, putting extra strain on the CPU, interrupting the computer’s most basic operations, or damaging the system. Again, a Trojan is extremely good at tricking the users into believing that it is just an MP3 song, a movie, or a .txt file. As soon as you click it, the malware takes over, and there is little you can do to prevent it. A Trojan is a self-sustained program, meaning it is capable of inflicting damage with no control from the outside.

Trojan Virus vs. Trojan Malware — What’s the Difference?

We just called it a Trojan, Trojan virus/horse, and Trojan malware — what is the right term to use? Here is the thing: Viruses do not require the user to start them Trojans do. That’s the reason the right term is “Trojan” or “Trojan malware.” However, people on the Internet use all these terms and confuse each other. It’s crucial to understand how this program works so you can protect yourself from it.

How Do Trojans Work?

The most common case of a hidden Trojan is an email from what seems like a valid sender. As soon as you click on the attachment and open it, the malware automatically installs and runs. It spreads all over your hard disk and infects/damages as many documents as possible. If you would like to prevent trojans that you can just choose one of the best free antiviruses.

The Most Common and Dangerous Kinds of Trojan Malware

Let us take a fast look at the common kinds of Trojans and what they’re capable of.

Backdoor Trojan

Just as the name implies, this malware generates “backdoors” that the hacker uses later to get your device and command it. If you are not successful at deleting the malware ASAP, the hacker will have the ability to do anything he/she wants!

Fake AV Trojan

This one makes you believe that it’s really an antivirus but enables you to pay (with cash) to get detecting/getting rid of possible threats. The majority of the time, these dangers are fake and are there just for generating action.

Game-Thief Trojan

Nowadays, game accounts may cost a whole lot, especially if the owners have unique skins/weapons on them. This Trojan seeks and steals account information once you install it.

Mailfinder Trojan

Mailfinder does exactly that — finds passwords to email addresses and robs them.


These programs can spy on you, monitoring the programs you run, taking screenshots, and recording your keystrokes. Trojan-Spy is thought of as among the deadliest and most dangerous malware on the Internet.

DDoS Attack Trojan

AKA the Distributed Denial of Service Trojan, this malware attacks a network by overwhelming it with visitors. Because of this, the Network breaks. The cybercriminals use devices of different users to “siege” a sophisticated Network, such as that of a police station, a government center, or a financial institution.

Infostealer Trojan

Much like the other Trojans on our listing, the Infostealer has just 1 job: to steal precious data out of the computer/laptop/mobile device.

Downloader Trojan

The moment the Downloader infects your device, it begins to download/ install more complex malware so as to take over completely. On occasion, it installs adware which could have an even larger negative effect.

“Ransom” Trojan

The Ransom Trojan is a blackmailer. It requires a ransom to give you control of your apparatus. Yes, you can just remove it by paying the hacker. If you do not, the malware will block certain programs, make your CPU work slower, or even completely paralyze the apparatus.

RAT (Remote Access Trojan)

This malware provides the hacker complete control over a computer/gadget. It makes a remote network connection so the attacker can download and install anything he/she pleases. Spying is another frequent use for it.

SMS Trojan

Exclusive to mobile devices, the SMS Trojan is notorious for sending and intercepting messages that you send through your phone/tablet. Furthermore, it has a tendency to send texts to premium-rate amounts and force you to pay for that.

Trojan Banker

As you have probably guessed from the title, the Banker is just interested in your bank account. It watches your every action online carefully and finds a way to steal the passwords/logins.

Rootkit Trojan

These kinds of Trojans conceal the action of malware so that it can run on your computer without being detected.

Trojan IM

If you are a fan of instant messaging, the IM Trojan will be certain to steal your passwords and logins.


Even the best antiviruses are not always effective at detecting the Droppers. Hackers use them to put in their malware or to conceal their actions (yes, exactly like with Rootkit Trojans).
