Initiate a full system scan and allow the software to analyze all files and folders on your Mac. The scanning process may take some time, depending on the size and speed of your system. While the scan is taking place, it’s important not to interrupt or close the scanning window.
Once the scan is complete, the antivirus software will present you with a list of infected files, if any are found. Take note of the infected files and follow the software’s instructions to quarantine or remove them. It is recommended to remove any detected malware completely to ensure the effective elimination of the hijacker virus from your Mac.
Step 3: Removing Suspicious Applications And Extensions
When dealing with a hijacker virus on your Mac, it is crucial to identify and remove any suspicious applications and extensions that may have been installed without your knowledge. These malicious entities often disguise themselves as legitimate software or browser add-ons, making it imperative to thoroughly clean your system.
To begin this process, navigate to the “Applications” folder on your Mac and carefully review the list of installed applications. Look for any unfamiliar or suspicious programs, especially those with names that resemble well-known software. If you come across any such applications, move them to the Trash by right-clicking and selecting “Move to Trash.”
Similarly, check your web browsers for any suspicious extensions that may have been added. Open each browser and access its settings or preferences menu. Look for the extensions or plugins section and carefully inspect the list. Remove any suspicious or unfamiliar extensions by clicking on the trash bin icon next to them.
It’s important to note that while removing suspicious applications and extensions is a crucial step in getting rid of a hijacker virus, additional measures should be taken to ensure complete removal and security.
Step 4: Resetting Your Web Browsers
Resetting your web browsers is an essential step in getting rid of a hijacker virus on your Mac. Hijacker viruses can modify your browser settings, such as your homepage, search engine, and extensions, without your consent. Resetting your browsers to their default settings can help remove any unwanted changes made by the virus.
To reset Safari, go to the “Safari” menu and select “Reset Safari.” Make sure to check all the options for a complete reset. This will remove all saved website data, including cookies and login information, so make sure to save any important data before proceeding.
For Google Chrome, click on the three-dot menu icon and go to “Settings.” Scroll down and click on “Advanced” to expand the settings. Under the “Reset and clean up” section, select “Restore settings to their original defaults.” Confirm the reset and restart the browser.
To reset Firefox, click on the menu icon and select “Help” followed by “Troubleshooting Information.” Click on the “Refresh Firefox” button in the top-right corner and confirm the reset.
Remember to reconfigure your browser settings and reinstall any necessary extensions or plugins after resetting.
Step 5: Updating Your Mac’s Operating System And Software
Updating your Mac’s operating system and software is an essential step in getting rid of a hijacker virus. Hackers often exploit vulnerabilities in outdated software, so keeping your system up to date is crucial for security. Follow these steps to ensure your Mac is running the latest version:
1. Click on the Apple menu in the top-left corner of your screen and select “System Preferences.”
2. In the System Preferences window, click on “Software Update.”
3. If there are any available updates, click on the “Update Now” button to install them.
4. Follow the prompts and enter your administrator password, if required.

In addition to updating the operating system, it’s equally important to keep all your software up to date. Check for updates in the App Store or by visiting the official websites of your installed applications. Regularly updating your software will patch any security holes and minimize the risk of being infected by a hijacker virus.
Remember to enable automatic updates for your Mac and software whenever possible to ensure continuous protection against potential threats.
Step 6: Enabling And Configuring Firewall Protection
Firewall protection is a crucial step in securing your Mac against hijacker viruses. By enabling and configuring the firewall, you create an additional layer of defense that acts as a barrier between your computer and potential threats.
To enable the firewall on your Mac, follow these steps:
1. Go to the Apple menu and click on “System Preferences.”
2. Select “Security & Privacy” and click on the “Firewall” tab.
3. Click the lock icon at the bottom left corner and enter your administrator password to make changes.

Once the firewall is enabled, you can further configure its settings to enhance your Mac’s security. Under the “Firewall” tab, click on “Firewall Options” to access the additional settings. Here, you can block specific applications or services from accessing your network, customize incoming connections, and enable stealth mode to make your Mac invisible to unauthorized users.
By taking the time to enable and configure the firewall on your Mac, you greatly reduce the risk of hijacker viruses and other malicious attacks. Keep in mind to regularly update your firewall settings and check for any alerts or notifications to ensure your Mac stays protected.
Step 7: Setting Up A Strong Password And Activating Two-Factor Authentication
In order to strengthen your Mac’s security after dealing with a hijacker virus, it is crucial to set up a strong password and activate two-factor authentication. This step ensures that unauthorized access to your device and personal information becomes extremely difficult.
To start, choose a password that is unique, complex, and easy for you to remember, but difficult for others to guess. Include a combination of upper and lower case letters, numbers, and special characters. Avoid using common phrases or personal information that could be easily associated with you.
Once you have set up a strong password, enable two-factor authentication (2FA) for your Mac. 2FA provides an extra layer of security by requiring a second form of verification, typically a unique code sent to your registered device, in addition to your password. This prevents unauthorized access to your device even if someone manages to obtain your password.
