Remove a Trojan Virus


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

A Trojan (or a Trojan horse) is a term, used in the cyber circles to describe a very malicious computer program, which is created to secretly infect various computer systems and to initiate some harmful activity. Usually, such a malicious program can cause harm in many ways. It typically is related to acts of online fraud and theft, as well as system corruption, data deletion, and distribution of other viruses, such as Ransomware. The hackers, who develop Trojan horse infections, may often use them to gain unauthorized access to the infected machine and establish remote control over its processes. As soon as such a malware infiltrates the computer, it tries to remain hidden for as long as possible. Unlike most computer threats, which usually have some symptoms, that can give them away, detecting the Trojan can be quite difficult. In most of the cases, since there are no typical signs, which can draw attention, the users may not be able to spot it on their own. Therefore they may need reliable anti-virus software to scan the system and have the stealthy Trojan removed.

The activity of each Trojan horse depends entirely on the intentions of its author. Most programs of this kind are capable of infecting, corrupting and overwriting files and different important system components. They can also format disks and destroy the entire OS. Many Trojans are related to banking fraud and theft where sensitive financial data is stolen or bank accounts are drained with their help. Such harmful pieces may also track down the victim’s activity and keystrokes and may steal passwords, login credentials, and sensitive personal information. The hackers can use them to create backdoors for other malware or to establish remote control over the existing components. Trojans are also related to Denial of Service (DoS) attacks, as well as other network attacks, BotNets, cryptocurrency mining and spam distribution.

How can a Trojan horse infect a computer?

It is typical for the Trojans to infect the computer without the users’ knowledge. For that, they usually spread themselves with the help of camouflaged transmitters and often pretend to be seemingly-harmless web content. Here are some of the most common ways such malicious programs may use to get into the system:  

  • Spam emails, infected links, and attachments. Many Trojans get distributed through infected emails, and harmful messages on file-sharing networks and online chats. They often resemble simple links, funny pics, attachments, sent from friends, or different free downloadable files.
  • System weaknesses and web browser vulnerabilities. Outdated virus definitions and old system security patches can often allow new and more sophisticated Trojan infections to sneak undetected. Also, when your browser has no proper security settings, or you visit insecure web locations, landing on illegal sites, filled with harmful code, is more likely to happen. 
  • Infected program installers, harmful download links, .exe files. Very commonly Trojans may get installed via infected software bundles and .exe files, harmful downloads, torrents, pirated content, and various sketchy apps and add-ons.
  • Fake software update requests and legitimate-looking program setups. Some Trojans may get integrated into certain free applications and their features and may fake software update request messages. Recently, even legitimate-looking programs may have their installation or update kit faked by this malware, which only aims to trick the people into clicking on the harmful payload.
  • Malvertising. Fake ads, misleading links, too-good-to-be-true offers, “you won a prize” pop-ups and similar messages are often used by the cyber criminals to spread this malware.

All in all, the consequences of having a Trojan horse on your machine can be unpredictable. That’s why, it is a good idea to protect your PC with reliable antivirus software, run regular scans of your OS, get the latest security patches and try not to interact with anything, which appears shady or potentially dangerous.
