More about browser hijackers

Most often, browser hijackers are promoted as useful and legitimate apps. The purpose of these apps is to promote shady search engines. It is worth noting that not all browser-hijacking apps alter the settings of web browsers to promote those search engines. Either way, it is advisable to use only legitimate search engines.

Examples of apps classified as browser hijackers are Racing Cars Tab, Nature NewTab Extension, and Nautica.

How did bestdiscoveries.co promoting software install on my computer?

One of the common methods to lure users into installing/adding browser hijackers is to bundle them with other programs. Users inadvertently install browser hijackers as they fail to deselect them during installations by ignoring the "Advanced," "Custom," or similar settings.

Browser hijackers are also distributed through deceptive advertisements, fake installers, and shady websites. Most of the time, users download and install/add these hijackers without being aware of their purpose or consequences.

How to avoid installation of browser hijackers?

To avoid installing/adding browser hijackers and other unwanted apps, download applications only from trustworthy sources, such as official websites and legitimate app stores. Avoid downloading files or apps from unofficial pages, third-party downloaders, Peer-to-Peer networks, and similar sources.

Be cautious when browsing the web, and avoid clicking on suspicious buttons and ads displayed on questionable websites. Also, deselect any unwanted applications that may be included in the downloader or installer before downloading or installing any software.

If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
