How to remove a browser hijacker from your Mac
Browser hijackers have become one of the most common types of malware on the Mac. Whether you use Safari, Chrome, Firefox, or another browser entirely, you're at risk of browser hijacking. Here, we'll tell you how you can tell if your browser has been hijacked and how to remove the culprit.
What is browser hijacker?
It's a type of malware that takes control of your web browser once it has been downloaded and installed. Typically, it will change your homepage to one hacker wants you to visit and change your default search engine to one that allows the hacker to monitor your searches or clicks.
The gathered information will then be used to display adverts. Some browser hijacking also involves installing toolbars that claim to find discounts or offer coupons for online shopping sites. In reality, this is adware designed to get you to click on a link that will take you to a suspicious website to increase its advertising revenue.
Hijackers may also download files to your Mac that monitor your activity or steal data. For example, your Mac may get infected with a software keylogger that can record your banking and email authentication information.
Some hijackers have become so widespread and easily recognizable that even non-tech-savvy users might have heard of them. They often bear names that make them sound like search or shopping extensions. Here are some examples:
- Pitch of Case
- Ask Toolbar
- Search Quick or CoolWebSearch
- Time Search Now
- Booking app
- Coupon Server
How browser hijacking works and why it is dangerous
All the browser hijackers above sneak into your Mac bundled with legitimate applications, browser toolbars, add-ons, or disguise themselves as updates, like Flash Player. Unaware users allow these additional downloads, sometimes when they simply agree to the site's terms and conditions. The next thing you know, these unwanted apps change your default search engine according to the hackers' preferences.
Now, taking control over your system, hijackers can direct you to whatever site they wish. Many of those pages would probably contain computer malware, viruses, and other dangerous cyber threats that can severely affect your device. Not to mention that you'll also experience a significant drop in your Mac's performance.
How can I tell if my browser has been hijacked?
Spam, pop-ups, and changed settings can be possible symptoms of browser hijacking. Answer the question below to detect if your device has been compromised:
- Has your browser's homepage changed without your knowledge?
- Has your default search engine changed?
- Have you started experiencing an increase in pop-up advertisement alerts?
- Is your browser running more slowly than it used to or behaving erratically?
- Does your search engine redirect you to random websites?
- Have you noticed multiple toolbars that you didn't install on a web browser?
If the answer to those questions is 'yes,' it's likely that your browser has been hijacked.
How can I avoid being hijacked?
Hijackers find their way onto your Mac using many different techniques. However, they are downloaded only after the user-initiated action, like clicking a link in a phishing email or proceeding to a questionable website.
Let's review some rules you should follow before talking about removing a browser hijacker from your Mac.
- Don't click on any email link unless you know where it leads.
- Don't respond to pop-up adverts claiming a component, like Flash Player, is outdated or that your system needs to be updated.
- Avoid downloading apps from free software download sites that use their proprietary download manager.
- Keep your OS and all your apps up to date – CleanMyMac X has an updater that scans apps installed on your Mac, checks for updates, and automatically installs new versions.
