How to remove browser hijackers from Mac computers

What is a browser hijacker?

When installed on devices, internet browsers automatically force-open fake or legitimate search engines (and/or other dubious websites). Typically, these redirects occur when attempts are made to search via the URL bar or when a new browser tab/window is opened. Dubious software within the browser hijacker category achieves this by making certain modifications to browser settings. Additionally, most browser hijackers have data tracking capabilities, which are used to monitor browsing activity and collect sensitive information extracted from it. Browser hijackers are also classified as Potentially Unwanted Applications (PUAs), since many users download/install them unintentionally.

Browser hijackers typically target Google Chrome, Safari, Mozilla Firefox and other popular browsers with large user bases. These rogue applications operate by assigning the addresses of specific search engines as the homepage, default search engine and new tab/window URLs. Therefore, browsers with any/all of the aforementioned options set to Yahoo! (search.yahoo.com) will redirect to this search engine due to a browser hijacker having infiltrated the system. As mentioned, these redirects to Yahoo! are caused when a new browser tab/window is opened and/or search query is typed into the URL bar. Note that search.yahoo.com is a legitimate search engine developed by the Yahoo! web service provider, however, this is more than an issue of search engine preference, as browser hijackers are notorious for data tracking. They usually monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather vulnerable data derived from it (IP addresses, geolocations and other details). The collected data is highly likely to contain personally identifiable information, which developers monetize by sharing with and/or selling to third parties (potentially, cyber criminals). Therefore, the presence of browser hijackers on browsers/systems can cause serious privacy concerns, financial loss and even result in identity theft. Furthermore, recovering a hijacked browser without removing the software affecting it is impossible, since any changes users attempt to make to their browsers are undone, if access to the settings is allowed at all. To ensure device integrity and user safety, you are strongly advised to eliminate all suspicious applications and likewise suspect browser extensions/plug-ins immediately upon detection.

Browser hijackers may seem normal and harmless. This software typically offers various "useful" and functionality, however, the advertised features seldom work as promised and, in most cases, do not work at all. Bright StartNiceTab StartPage and MacAppExtensions are some examples of other browser hijackers. The search engines they promote are often fake, despite their legitimate appearance. For example, searches.networksearch.handlersection.comsearches.cloud, and searchsnow.com amongst countless others. As these bogus search tools are rarely capable of providing unique search results, they simply redirect (or cause redirection chains leading) to Yahoo, Google, Bing and other genuine search engines. The only purpose of browser hijackers and other PUAs is to generate revenue for the developers.

How did a browser hijacker install on my computer?

PUAs (browser hijackers included) are distributed via the download/installation set-ups of other products. This deceptive marketing technique of packing regular software with unwanted or malicious additions is called "bundling". By rushing through download/installation processes (e.g. ignoring terms, skipping steps and sections, using pre-set options, etc.), many users risk inadvertently allowing dubious and bundled content into their devices. Some PUAs also have "official" promotional web pages, from which they can be downloaded. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications

You are advised to research all products to verify their legitimacy, prior to download/installation or purchase. All downloads must be done from official and trustworthy sources. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders can offer deceptive and bundled content - they are are untrusted download sources and should be avoided. When downloading/installing, it is important to read the terms, explore all possible options, use the "Custom" or "Advanced" settings and opt-out of supplementary apps, tools, features and other additions. It is crucial to exercise caution when browsing. Intrusive ads may seem legitimate, however, they often redirect to dubious sites (e.g. gambling, pornography, adult-dating, etc.). If you encounter ads or redirects of this kind, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
