Trojan horse virus FAQ

Even in 2021, Trojans are still using deception and social engineering to trick unsuspecting users into running seemingly benign computer programs that hide malevolent ulterior motives. Trojans can download code or software that looks legitimate but, in reality, it will take control of your device and install malicious threats including malware, ransomware, and spyware.

Trojans aren’t limited to Windows laptops and desktop computers; they can also impact Macs and mobile devices. Our solutions, such as Malwarebytes for WindowsMalwarebytes for Android, and Malwarebytes for Mac, function as Trojan protection for all your devices.

If you’re wondering how to get rid of a Trojan, it’s highly recommended you use anti-Trojan software to protect your devices. It’s far easier to proactively stop a Trojan from infecting your computer with a solution like our free Trojan scanner than scrambling to address it after the fact.

When you’re looking for Trojan protection, don’t just settle for just a traditional antivirus tool. Look for a solution that also secures you from malware, viruses, and more, with antivirus plus anti-malware protection.

There is a difference, though, between the free Trojan scanner our Malwarebytes Premium solution. The free Trojan scanner removes existing Trojans whereas Malwarebytes Premium proactively scans your device for Trojans to prevent them from doing harm.

You might assume a Trojan is a type of virus or a worm, but it’s really neither. It’s actually a delivery mechanism for infecting your device with cybersecurity threats, from ransomware that immediately demands money, to spyware that conceals itself while it steals personal and financial data. 

So, how to remove a "Trojan virus?" You can use our virus and malware scanner to check for Trojans or other types of malware and then remove them from your device. 

Trojans can infect your computer in any number of ways: they can look like free software and music to browser ads to seemingly legitimate apps. However, they can’t infect your device on their own—it takes user interaction to spread them such as opening a malicious email attachment or unintentionally downloading and running a fake file.

Here are some common ways Trojan software spreads on your device:

  • Downloading infected applications or unknown free programs
  • Opening infected email attachments
  • Visiting shady websites such as a site that pretends to stream a popular movie but only if you download a certain video codec which is really a Trojan
  • Any other social engineering scheme that disguises itself by taking advantage of the latest trends like the COVID-19 crisis

The best way to clean up a Trojan infection is to use Malwarebytes’ free trojan scanner, and then consider Malwarebytes Premium for proactive protection against future Trojan infections. Malwarebytes Premium will initiate a scan for Trojans and then remove Trojans so they can’t cause further damage.
