How to Remove a Trojan Virus in 2019

Trojan or Trojan horse is a name synonymous with the story of the Trojan wars. In the tale, the Greeks built a wooden horse, placed some soldiers inside, and brought the horse near the city walls of Troy. Some troops appeared to sail away, leaving a soldier behind who convinced the Trojans that the horse is a gift and that they have conceded defeat. The Trojans pulled the horse inside their impenetrable city and went ahead to celebrate their victory. At night, the soldiers hidden inside the horse came out and opened the gate for the troops who had appeared to sail away. And that how the city of Troy was destroyed.

The modern computer Trojan works similarly to the Greek Trojan horse. For instance, you might download a free/cracked software laden with Trojan.

What is a Trojan?

Similar to the above Greek story, a Trojan is a malware that masquerades itself as something useful or legitimate. It does this to hide its real malicious intent to get into a securely protected computing environment. Unlike other malware that propagates on their own, Trojans need to be downloaded or manually installed by other malware.

Types of Trojans

Trojans are classified according to what they do. This is because malicious people usually use Trojans as delivery malware to deliver other malware or propagate dangerous attacks. Common types of Trojans include;

  • Trojan Backdoors/Exploits: These Trojans create remote access by taking advantage of vulnerabilities or security flaws in a system. Malicious people usually use these backdoors to gain control of the infected device. Cybercriminals can then do anything they want on the device and even use the device for further attacks, i.e., on a network.
  • Trojans Rootkit: rootkits provide administrators privileges to other malware or malicious people. A rootkit Trojan ensures that the other malware is not discovered while it wreaks havoc on the victim’s device.
  • Trojan-Downloader/Dropper: these are the most common types of Trojans. Malicious people use these Trojans to download and install other malware on an infected system. They are most efficient as they appear as legitimate apps, and most antivirus tools are not capable of scanning what the Trojans carry.
  • FakeAVTrojans: These Trojans masquerade as antivirus software. For instance, they offer to scan your computer free and report some nasty threats and malware. To remove the threats and malware, you have to pay some amount of money. In reality, the threats and malware are non-existent, and it is a way malicious people use to extort money from unsuspecting victims.

Other types of Trojans include; destructive Trojans, denial of service Trojans, FTP Trojans, and proxy Trojans.

How to know if your device has a Trojan?

Generally, it is hard to tell if your device has a Trojan unless you scan for one. However, there are a few telltale signs that can indicate if your device has a Trojan. But because Trojans are used to deliver other malware, these signs might point to other malware. The signs include;

  • Your device is getting slow: Trojans carry out background operations such as downloading, installing and allowing malicious people remote access. These operations use a lot of computing resources such CPU power and RAM. This makes your devices generally slow, and times, your legitimate apps may not have enough resources to work correctly, and this may lead to your device freezing and even crashing.
  • Unauthorized system operations: Trojans may alter your device’s settings so that an intruder can install rogue programs and carry out malicious activities. If you see apps and programs, you did not install, or new toolbars and plugins that you do not recognize, there is a high chance your device has a Trojan.
  • Sudden loss of disk space: other malware downloaded by Trojans such as spyware, worms, and viruses can quickly fill your storage in no time. If your disk is getting full and you do not see the content, probably you have a Trojan.
  • A surge on internet/bandwidth usage: cybercriminals use Trojans to remotely access your device and download/upload content that suits them. In addition, other Trojans download and install other malware or apps that might further use your bandwidth.

How to remove a Trojan from your device

Since Trojans masquerade as legitimate apps, the best way to remove Trojans is by using reputable antimalware/antivirus software tools. The most recommended tool is Malwarebytes, as it is known to detect most Trojans, and it uses a better heuristics engine. Proceed as follows to scan and remove Trojans using Malwarebytes.

  1. Download, install, and launch Malwarebytes Antimalware software.
  2. On the Dashboard section, click the Scan now button to perform a threat scan.
  3. On the results that show up, select the items you want to quarantine/disable, if any.
  4. Click the next button to select preinstalled software you want to quarantine/disable – the detected software might be the one injecting Trojans.
  5. Lastly, click the Quarantine button to move selected items to the quarantine section.
  6. If you want to get rid of the detected items, open the Quarantine section, and click the Delete button.

Once your device is clean, take care of your sensitive information by changing your username and passwords. You might not know what was compromised. Additionally, uninstall any residual programs that you did not install.
