Trojan Virus on Mac: How to Detect & Remove from Your MacBook

Guide to Prevent and Clearing Trojan Viruses for Mac Computers

Trojan virus is a common way for malware to infect Macs and other computers. After a Mac is infected with Trojan virus, it may cause various damage. Depending on the payload carried by the Trojan virus, it can cause the computer to slow down, steal files, control your computer to send spam, install ransomware, and more.

Therefore, the earlier you detect and clear Trojan viruses on your Mac, the better. The shorter the infection time, the less damage the malware causes. This guide will explain how to determine if your Mac is infected with Trojan virus, how to remove Trojan virus, and how to prevent future infections.

What is a Trojan virus?

Trojan virus or Trojan is a type of malware that hides its true intentions in some way. As the name suggests, it originates from Greek mythology. But unlike Greek soldiers hiding in giant Trojans to invade Trojans, these Trojan viruses contain malware hidden in seemingly harmless applications or email attachments. Usually, it will only be activated when you try to open an infected file.

In the past, Mac computers were almost uninfected with viruses, but now the situation is very different. As Apple computers become more popular, they are becoming increasingly popular among hackers - meaning that Macs, like other systems, will also be infected with Trojan viruses. In February 2022, Microsoft's security team discovered that malware was hidden in seemingly legitimate applications (such as video tools) as well as pop-up ads. This Mac Trojan virus can bypass macOS's security features and even delete evidence of its own existence.

How to determine whether your Mac is infected with Trojan virus?

By definition, Trojan viruses try to hide themselves—at least until they release their payload. When this happens, you may notice some classic signs of malware infection.

Signs that your Mac may be infected with Trojan virus:

• Extremely slow performance
• Crash and Freeze
• Delete the file by yourself
• Your antivirus software is disabled
• The number of pop-up windows is increasing
• Your web browser is redirected

How to detect Trojan virus on Mac

If your Mac has performance issues and other suspicious activity, this may mean you may be infected with malware, but that's just part of it. If you know what you're looking for, you can search for the malware manually and try to delete it. But to really determine if there is a Trojan virus on your Mac, you need to use a malware scanner, such as MacKeeper's antivirus software.

The following is how to detect Trojan viruses on MacKeeper's antivirus software:

1. Open MacKeeper and select "Anti-virus" from the sidebar.
2. Click "Start Scan".
3. Waiting for the scan to complete. If MacKeeper discovers Trojan viruses or other malware, it will be listed in the scan results.

This tool will search your entire Mac or selected location and compare files with a list of known viruses, spyware, Trojan viruses, and other malware.

Select the correct program to remove Trojan viruses

It's easy to remove Trojan viruses from your Mac with good security measures and MacKeeper's antivirus software. You can do a lot of detection and deletion manually, but it's a lengthy and complex approach. Yes, many Trojans will install files in your library folder, for example, but they may also be located elsewhere on your Mac – and you must also know what you are looking for.

If you find Trojan virus on your Mac, if you can, you should delete suspicious applications, extensions, etc. You can do this manually or save time using MacKeeper's smart uninstaller.

Resetting your Mac will also work, but it's an extreme option. Before you do this, try using MacKeeper's antivirus software and be prepared to remove various malware, including Trojan viruses, after a few clicks of the mouse.
