In case you have been searching for information on how to remove a Trojan Horse named OSX/Linker from your computer, search no more. On this page, you will find a detailed removal guide with step-by-step instructions on how to locate and safely eliminate this nasty infection from your system. In the guide, you will also see a recommended professional OSX/Linker Malware removal tool for automatic assistance. But before you go straight to the guide, let’s start from the beginning: what is really a Trojan Horse and what can a threat like OSX/Linker Malware do to a computer?

Trojans are a type of malware whose main purpose is to give remote access to a system and launch different harmful tasks on it. The name of those threats is inspired by the mythical wooden horse used by the Greeks to enter the seemingly invincible city of Troy without raising suspicions. Similarly, these malicious programs try to pass unnoticed, opening a backdoor for a remote attacker to enter the computer.

However, oftentimes, Trojans do more than just provide a backdoor – they are very versatile pieces of malware which can also be used to record keystrokes and visited pages, transfer data from the computer to remote servers, corrupt files, steal information, distribute other viruses, and especially Ransomware infections, create security holes, and much more.

And, as we said, the Trojan typically try to go unnoticed, so it would not be a huge surprise if a threat like OSX/Linker Malware shows absolutely no symptoms of its presence in the system for a long time. Basically, this type of malware is intended to hide processes that may make the user suspicious.

How? The infection is typically installed on the computer with administrator privileges or root permissions. This way, the hacker who controls it can have full control of the system and hide certain processes and files, prevent the antivirus from doing its job, skip, etc. This prevents you from detecting that there has been a compromise in your system, which makes it very difficult to locate and remove the Trojan on time.

How can we become infected?

There are so many ways in which a Trojan such as OSX/Linker, Be Aware Mac App or CookieMiner can get inside your machine. An infection can happen due to a vulnerability in a program that you have installed (such as Flash, Java, Adobe Reader) or if you download an infected file which, when opened, executes malicious code that silently installs the malware without your knowledge. The hackers usually use some seemingly harmless pieces of content such as images, email attachments, links, fake ads, misleading offers, or infected web pages, which, once interacted with, trigger the infection.

Unfortunately, due to a lack of symptoms, it may take you weeks or even months to realize that you have been compromised. That’s why the best method to protect yourself against Trojans and to detect and remove infections like OSX/Linker Malware on time is to use reliable security software. A good antivirus can scan the system for malicious processes in the background and notify you about your system’s condition. There is no need to explain to you why you should take immediate action if a Trojan gets detected. The longer the malware remains in the computer, the greater the harm it may cause. That’s why you must not lose time and why you should follow the instructions below to quickly get rid of OSX/Linker Malware.

Detection Tool

Remove OSX/Linker Malware

Step1

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

Start Activity Monitor by opening up Finder, then proceed to activity-monitor

Once there, look at all the processes: if you believe any of them are hijacking your results, or are part of the problem, highlight the process with your mouse, then click the “i” button at the top. This will open up the following box:

chromeinfo

Now click on Sample at the bottom:

chromesample

Do this for all processes you believe are part of the threat, and run any suspicious files in our online virus scanner, then delete the malicious files:

Step3

The next step is to safely launch Safari again. Press and hold the Shift key while relaunching Safari. This will prevent Safari’s previously opened pages from loading again. Once Safari is opened up, you can release the Shift key.

On the off chance that you are still having trouble with scripts interrupting the closing of unwanted pages in Safari, you may need to take some additional measures.

First, Force Quit Safari again.

Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.

Step4

Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

Preferences in Safari

and then again on the Extensions tab,

Select and Uninstall any extensions that you don’t recognize by clicking on the Uninstall button. If you are not sure and don’t want to take any risks you can safely uninstall all extensions, none are required for normal system operation.
Step5

The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

Again select Preferences in the Safari Menu, but this time click on the Privacy tab,
Privacy in Safari

Now click on Remove All Website Data, confirm with Remove Now. Keep in mind that after you do this all stored website data will be deleted. You will need to sign-in again for all websites that require any form of authentication.

Still in the Preferences menu, hit the General tab

General Tab in Safari

Check if your Homepage is the one you have selected, if not change it to whatever you prefer.
Default Home Page

Select the History menu this time, and click on Clear History. This way you will prevent accidentally opening a problematic web page again.
