This page aims to help you remove Trojan.Maljava. Our removal instructions work for every version of Windows.

“Trojan horse” is a term that is extremely popular among all the people who use the Internet. Almost every online user has heard the word “Trojan” at least once and has probably encountered such malware in one way or another. This is so because presently, Trojan horses represent the most numerous and the most widely-spread group of malware on the Internet and, as per some recent statistics, every three out of four virus infections are caused by these malicious pieces of software. The Trojan programs usually appear harmless at first sight and tend to trick the people into running them, believing they are some interesting apps, useful components or tools. However, the moment they become part of the system, they secretly launch various malicious activities behind the back of the users.

In the text below, we are going to discuss more about the general characteristics of this malware group as well as the features of one particular Trojan Horse representative called Trojan.Maljava which has been recently reported by a number of users and cyber-security researchers. Those of you who have been infected by this new Trojan will probably find the instructions in the Removal Guide below useful. They are created to help even a non-experienced user detect and remove the infection without risk for the system.

Trojan horses and their characteristics:

All the viruses that fall under this category have certain similar characteristics that you need to be aware of. The stealthy infection is one of them. A threat like Trojan.Maljava will try to get inside your computer without being noticed. It may even try to bypass your antivirus software, pretending to be some legitimate program or software tool. Once inside the system, the infection will also try to hide its traces and not to trigger any visible symptoms of its criminal activities. From system destruction, file corruption, theft of information and credentials to blackmailing and direct harassment of the victim – you can expect almost anything from a Trojan horse attack. The hackers who create such malicious pieces of software can program them to perform specific criminal tasks with surprising precision or they can use them as multifunctional tools for destruction, fraud and theft of different scale.

What may a threat like Trojan.Maljava be after?

As we said, Trojans may significantly differ  in their activities and criminal purposes. If you have a threat like Trojan.Maljava on your system, you basically have to be prepared for some of the following:

  • Destruction of your data or some sort of system corruption and malfunction: Crashing your entire system is one of the possible purposes of a virus from the Trojan Horse family. The hackers may use the infection to secretly modify certain system processes, delete files or format your disks in one single command. They may also exploit the RAM and the CPU resources for launching other harmful processes without your knowledge. Sudden system errors, crashes and significant slow-down in the productivity of the computer could be some of the consequences.
  • Espionage and theft of credentials: Occasionally, a Trojan like Trojan.Maljava could be exploited as a tool for espionage, which can secretly hack into your web camera or mic and track down every movement, conversation or activity that you do while the infected computer is on. The crooks may also set the malware to monitor your keystrokes and login credentials or transfer certain files from your computer to their remote servers.
  • Distribution of viruses and advanced malware infections: Many Trojan horses could also be used as a backdoor for other malware. In fact, one of the favorite ways for the criminals to insert viruses such as Ransomware, Spyware or other sophisticated threats inside the computer is through a Trojan-based backdoor, which can provide the other malware with a gateway inside the targeted system.

Which are the most common sources of Trojans and how can one get infected?

Very often, threats like Trojan.Maljava may be incorporated in some illegal web pages, sketchy ads, torrents, free software installers and shareware platforms. Such tricky software may also be contained within a video or an audio file, some interesting image or a spam email attachment. Even a harmless-looking text document could infect you the moment you click on it if you are not careful. Sadly, it is oftentimes really difficult to distinguish a malicious transmitter from normal and harmless content – that’s why the best way to protect yourself is to invest in a reliable antivirus/anti-malware software program such as the professional removal tool, which is available on this page. In most of the cases, the absence of such software is the main reason for infection, as well as the careless online behavior of the user.

Can Trojan.Maljava be removed successfully and without risk for the system?

Dealing with a Trojan horse is a real challenge that requires your full focus and your cautiousness. However, if you carefully follow the instructions in the Removal Guide below, you may be able to detect and remove Trojan.Maljava effectively.
