Trojan Detected by Gateway AV from Here’s What You Should Do

Computer Virus Trojan

Is there a Trojan detected by gateway AV from on your computer? If so, then you have come to the right place. In this post, we aim to share everything we know about Trojan viruses on Macs.

Although some know for a fact that the latest Mac versions are not susceptible to malicious attacks, they still panic when they see a Trojan virus. They don’t seem to know that downloading a virus on their computers won’t cause any damage. But how is this possible?

MacOS works in a way that prevents dangerous files from becoming executable software. It does not scan files individually. It does not look for any suspicious patterns as well. Its system directories are secured and locked, which means nothing is available for modification. Anything downloaded will require the owner’s approval before it can be installed.

Now, we understand if you still feel distressed if your Mac is infected with a Trojan virus. After all, it’s quite sneaky, disguising itself as something that looks legit. Oftentimes, it pretends to be a piece of movie. There are also times when it hides its true identity by cloaking itself in a software installer.

Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.

But again, we want you to calm down when you see a Trojan virus on your Mac. Take it from us, it’s fairly easy to deal with. But before we share how, let’s first understand what a Trojan virus is.

What Is a Trojan Virus?

Also called a Trojan Horse, a Trojan virus is a cyber threat that has the same impact as the Wooden Horse of Troy. That horse was once used to trick Troy’s defenders into giving enemy soldiers access to the city.

As for Trojan viruses on Macs, they work by tricking users into downloading them. They do this by disguising themselves as software that looks legit. Sometimes, they also conceal themselves in fake software updates. Even worse, they occasionally pretend to be antivirus tools.

How to Know If a Trojan Virus Infected Your Mac

The signs of a Trojan virus are similar to those of other types of viruses. Here they are:

  • Your Mac begins to behave strangely and does things that it’s not supposed to do.
  • Your Mac begins to run so slow that you cannot even open a single app.
  • You see adverts popping up on your desktop randomly.
  • Your malware scanner confirms that a Trojan virus has successfully infiltrated your system.

How to Remove Trojan from Your Mac

If your system detected a Trojan virus, be sure to calm down and take a deep breath. And then, follow this detailed guide on what to do if a Trojan virus from has been detected in your Mac:

1. Delete Browser Extensions.

Sometimes, malware disguises itself as browser extensions. To remove them, follow these steps:


  1. Open Safari.
  2. Go to the Safari Menu and select Preferences.
  3. Navigate to the Extensions tab.
  4. Check the list of all the extensions installed in Safari. Click on any extension that you think is suspicious. If you don’t remember installing it, hit Uninstall.
  5. Repeat step 4 until all the suspicious-looking extensions are removed.


  1. Open Chrome.
  2. Navigate to the three-dotted menu and select Preferences.
  3. Go to More Tools.
  4. Select Extensions.
  5. Remove any extensions that you don’t recognize.


  1. Open Firefox.
  2. Navigate to Tools.
  3. Select Extensions.
  4. Review all the extensions in the list and remove those that you do not recognize.

2. Uninstall Suspicious Apps.

Again, malware comes in different forms. It can even disguise itself as security software that helps get rid of viruses.

Now, if you’ve unintentionally downloaded a fraudulent software, uninstall it right away. Here’s how:

  1. Open the Applications folder.
  2. Locate the fake software and drag it to Trash.
  3. Next, go to your Library folder.
  4. Check the Application Support folder for any files related to the recently deleted software. Drag them to Trash.
  5. Do the same with the Launch Daemons and Launch Agents But be careful not to delete system files as this may result in more Mac problems.
  6. Repeat the fourth step, but this time for the main Library folder.

3. Get Rid of Junk Files.

Sometimes, Trojan viruses hide themselves in junk folders and files. So, getting rid of them is definitely worth doing.

To delete junk files, you may manually check every folder in your Mac. However, take note that this process can be time-consuming. Your best option is to use a third-party Mac cleaning tool as it will do the task for you in less than a few minutes. Plus, it will also get your Mac to work faster and more efficiently.

4. Let a Professional Do It.

How to Protect Your Mac from Trojan Viruses

The best and easiest way to ensure your Mac does not get affected by a Trojan virus is to avoid downloading anything unless you are 100% sure what it really is.

What this means is do not click on any links sent via email. Do not even click on advertisements on the websites you visit.

If possible, enable your Mac’s firewall and keep your macOS updated to the most recent version. Take notice of warnings you see on your web browser when you are redirected to a website that looks suspicious.

When you download a tool or an app and your Mac asks if you trust it and wish to proceed, do not just hit Agree. Better yet, research the thing first. Make sure it is legit software you are downloading.

On a Final Note

Removing a Trojan virus from your Mac is not that difficult. In fact, you can do it in a matter of minutes. But as with all malware and threats, it’s better that you prevent Trojans from infiltrating your Mac in the first place. A little care and vigilance always go a long way, right?
