What is a browser hijacker?

A browser hijacker is a type of malicious software that alters your browser’s settings without your consent.

It normally changes your default homepage, installs suspicious extensions, and redirects your search engine results to unwanted or potentially harmful websites.

These hijackers often come bundled with free software or may sneak in through malicious programs.

How browser hijacking works

Browser hijacking works by exploiting vulnerabilities in a user’s web browser or operating system. Attackers can use various techniques, such as phishing, drive-by downloads, or bundling malware with legitimate software, to infect a user’s device.

Once infected, the browser hijacker can modify the user’s browser settings, such as the default homepage, default search engine, or new tab URL, without their consent.

In addition to altering these settings, the hijacker can install suspicious extensions or toolbars that collect user data or display unwanted advertisements.

These modifications can lead to a frustrating browsing experience, with constant redirects to unfamiliar sites and an influx of intrusive ads.

Symptoms of a browser hijacker

  • Slower web page loading: If your browser takes longer to load web pages, it may be because a browser hijacker is controlling your browsing activity and diverting you to malicious sites.
  • Unintentionally installed toolbars: The sudden appearance of browser toolbars in your browser can indicate that bundled software has installed a browser hijacker without your consent.
  • Redirected searches: If your searches are being redirected to different or suspicious websites, it’s a strong sign of browser hijacking, often leading to sites filled with advertisements or harmful content.
  • Increased pop-up ads and unwanted advertisements: An unusual increase in pop-up ads and unwanted advertisements can signal a browser hijacker, which often generates unwanted ads to generate revenue or trick you into clicking on malicious links.
  • Changed default search engine: If your default search engine has been replaced without your approval, a browser hijacker could be manipulating your search results and redirecting you to unsafe sites.

Note that not all browser hijackers are apparent. Some browser hijackers may operate covertly, spying on your browsing activity or stealing data, such as banking details and passwords, without obvious signs.

How to check for browser hijackers

Checking for browser hijackers is an essential step in maintaining your online security and preventing unwanted changes to your browser configuration.

Here’s how to do it:

Check browser settings and extensions

  1. Open your web browser and navigate to the preferences menu. Check if your homepage and default search engine have been altered without your consent. Unexpected changes here are a common sign of a browser hijacker.
  2. Go to the extensions or add-ons section of your browser. Look for any suspicious or unfamiliar extensions that you don’t remember installing. These could be responsible for the hijacking.
  3. Dive into your browser preferences to see if any other configurations have been modified. Pay close attention to settings related to your default search engine and homepage.

Check system login items

  1. Open System Settings (System Preferences on older macOS versions).
  2. Go to the General tab.
  3. Click on Login Items to see a list of programs set to launch automatically when you log in.
  4. Look for any suspicious apps or programs that you don’t recognize.
  5. If you find any unwanted apps, select them and click the minus (-) button to remove them from the list. This prevents them from launching at startup and potentially causing further issues.

How to remove browser hijackers from Mac

Removing browser hijackers can be challenging, but it’s essential to restore your web browser settings to their default state.

Here’s how to remove browser hijackers manually:

Remove suspicious apps from Mac

  1. Open Finder and navigate to the Applications folder.
  2. Look for any apps that seem suspicious or that you don’t remember installing.
  3. Before removing any app, check its reviews and ratings on the Chrome Web Store or other app stores. This can help you determine if other users have reported issues with the app.
  4. If you identify any suspicious apps, move them to the Trash. This action removes the app from your system.

  1. To complete the removal process, empty the Trash. This ensures that the app is completely deleted from your Mac.

Note: Exercise caution when removing apps from your Mac. Some apps may be legitimate and necessary for your system to function properly. Always research the app before removing it to avoid unintended consequences.

Clear the DNS cache

One effective way to get rid of browser hijackers on your Mac is by clearing the DNS cache. A browser hijacker can manipulate your DNS settings to redirect you to malicious websites, even after you’ve removed the hijacker itself.

Flushing the DNS cache helps ensure your system uses updated network settings, restoring proper browsing functionality.

Here’s how to clear the DNS cache on your Mac:

  1. Open Terminal from Applications > Utilities.
  2. Type the following command: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
  3. Press Return.
  4. Enter your admin password when prompted and press Return again.
  5. Restart your browser.

Reset settings of web browsers

Resetting browser settings is crucial for regaining control of your browser after a hijacking. This step reverses the unauthorized changes made by a hijacker, restoring your browser’s main settings to their original state.

Here’s how to reset the settings for Google Chrome, Safari, and Mozilla Firefox:

Google Chrome:

  1. Open Chrome.
  2. Click the three-dot menu icon in the upper right corner.
  3. Select Settings from the dropdown menu to access the browser settings window.
  4. In the Appearance section, toggle the switch next to the Show home button.
  5. Under the Show home button, enter your default homepage URL, or select New Tab page for the default Chrome browser start page.
  6. Scroll down to On startup and select Open the New Tab page, or specify pages to open on startup.

Safari:

  1. Open Safari.
  2. Click the Safari menu at the top of the screen and select Preferences (or Settings if using macOS Sequoia).
  3. In the General tab, find the Homepage field.
  4. Enter your default homepage URL or set it back to the default Safari start page.
  5. Check your search engine by clicking the Search tab in the same window.
  6. Under Search Engine, you will find a list of available search engines. Ensure the correct search engine is selected and change it if needed.
  7. Check Safari extensions by navigating to the Extensions tab.
  8. Review and remove any suspicious extensions.

Mozilla Firefox:

  1. Open Mozilla Firefox.
  2. Click on the menu icon in the top right corner.
  3. Select Preferences from the menu.
  4. In the Home panel, under New Windows and Tabs, choose Firefox Home for the default start page, or enter a custom URL.
  5. Select Add-ons from the menu to review and turn off any unfamiliar extensions.

Following these steps for each browser, you can reclaim control and ensure your online browsing remains secure and personalized to your preferences.

Reinstall your browser

In more severe cases, reinstalling your browser may be necessary. This is a last resort when other cleaning efforts fail to remove a browser hijacker.

Completely removing the browser can substantially disrupt the hijacker’s influence, and reinstalling the browser ensures you have a clean, hijacker-free platform with which to browse.

How to prevent Mac browser hijackers?

Prevention is always better than cure, especially for software like browser hijackers. Here are a few preventive measures you can adopt to safeguard your system from browser hijackers.

Avoid suspicious links

One of the best safety practices is to avoid clicking on suspicious links in emails, text messages, or pop-up notifications. Such links can initiate the download of browser hijackers, exposing your system to potential threats.

Keep your software updated

Regular updates to your operating system (OS) and browser are crucial to maintaining your system’s security.

Hijackers often exploit known vulnerabilities in the OS and browser, so keeping up-to-date with the latest security patches eliminates these weak points.

Avoid free software that unpack post-installation

Freeware programs that unpack additional software upon installation can be a security risk.

Be sure to understand the full scope of any software installation, including what will be downloaded and how it will interact with your system.

Opting for custom installation settings can also help you maintain control and avoid unintentional downloads.

Download Chrome extensions with caution

To prevent browser hijacking, it’s crucial to be careful when downloading extensions from the Chrome Web Store. While many Chrome extensions offer valuable features and enhancements, not all are created in your best interests.

Some might masquerade as legitimate tools while posing risks of hijacking or introducing other forms of malware.

Always research an extension thoroughly before installation: check its ratings, read user reviews, and verify the developer’s credibility.

Remember, adding Chrome extensions to your browser grants them various permissions, so only give access to trustworthy and necessary tools.

Being selective and vigilant can significantly reduce the risk of unintentional browser hijacking.

Summary

Removing a browser hijacker can be challenging, but antivirus software can help.

Here is a summary of the steps you can take to remove a browser hijacker:

  1. Check your browser settings and extensions for suspicious modifications.
  2. Check your system login items for any malware that may be modifying your browser settings.
  3. Check all recently modified applications for any suspicious activity.
  4. Check for suspicious auto-launch files that may be related to the browser hijacker.
  5. Use antivirus software to scan your Mac for malware and remove any detected threats.
  6. Reset your browser settings to the default values.
  7. Check the Chrome Web Store or other browser extension stores for any suspicious extensions.

By following these steps, you can remove a browser hijacker and protect your web browser settings from unauthorized modifications.

Remember to always be cautious when downloading software or clicking on links and to use strong passwords and two-factor authentication to protect your browser account.
