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 hijacking?
It’s a type of malware that once it has been downloaded and installed, takes control of your web browser. Typically, it will change your homepage to one that the hacker wants you to visit, and change your default search engine to one that allows the hacker to monitor your searches and clicks.
That 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 in order 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 e-mail authentication information.
There are a number of hijackers that have become well-known because they are so widespread. You might have heard of some of them. Many of them have names that make them sound like search or shopping extensions.
- Pitch of Case
- Search Quick
- Time Search Now
- Booking app
All of these hijackers sneak onto your Mac by bundling themselves with apparently legitimate applications or disguising themselves as updates, for example to Flash Player. And they all intercept your browser’s homepage and default search engine and change it to wherever the hacker wants you to go.
How can I tell if my browser has been hijacked?
There are a number of possible symptoms:
- Has your browser’s homepage changed without you changing it?
- Have you started seeing lots of adverts you wouldn’t normally see?
- Has your default search engine changed?
- Is your browser running more slowly than usual or behaving erratically?
If the answer to any of those questions is ‘yes’, it’s likely your browser has been hijacked.
How can I avoid being hijacked?
Hijackers find their way onto your Mac using a number of different techniques. However, in each case, they are downloaded after an action initiated by the user, such as clicking a link in a phishing email or on a questionable website.
- Don’t click on any link in an email or instant message unless you are certain where it leads.
- Don’t respond to pop-up adverts that claim a component, like Flash Player, is out of date, or that your system needs to be repaired.
- Avoid downloading apps from free software download sites that use their own proprietary download manager.
- Keep your operating system and all your apps up to date – CleanMyMac X has an updater that scans apps installed on your Mac, checks for updates, and then allows you to update all those that have new versions available.
