More about browser hijackers
Typically, browser hijackers are promoted as useful/legitimate applications. The purpose of these apps is to promote fake search engines. It is worth mentioning that not all browser hijackers modify the settings of web browsers. Sometimes, apps of this type collect browsing data and other information.
More examples of apps classified as browser hijackers are UltraCouponSearch, Mondy Search, and Quick Site.
How did discoverthebest.co promoting software install on my computer?
One of the most popular ways to trick users into adding browser hijackers to web browsers is to bundle them with other software. Browsers get hijacked after completing installations without deselecting browser hijackers (changing "Advanced", "Custom", or similar settings).
Also, browser hijackers are distributed via certain advertisements and deceptive websites. In most cases, users download and install/add browser hijackers without knowing what these apps do.
How to avoid installation of browser hijackers?
Download applications from official websites and stores. Do not use unofficial pages, third-party downloaders, P2P networks, and similar sources to download files/apps. Do not click on fake buttons and ads displayed on questionable pages. Deselect unwanted applications included in downloaders/installers before downloading/installing 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.
