Browser hijackers in general
Browser hijackers are designed to promote different search engines, both legitimate and untrustworthy ones. It is worth noting that not all apps of this nature modify web browser settings to promote search engines. Typically, users are unable to remove unwanted search engines from their web browser settings as long as browser-hijacking apps remain installed.
More examples of similar apps are My Notes Extension, Ultimate Basketball Fan Extension, and Nature Extension.

Users can inadvertently add or install browser hijackers through various means. Common methods include downloading and installing software from untrustworthy or malicious sources, clicking on deceptive advertisements or pop-ups, visiting compromised websites, and accepting bundled software installations without carefully reviewing the terms and conditions.
Additionally, users may unknowingly give permission for browser hijackers to install by not paying attention to the installation process or by clicking on misleading prompts.
How to avoid installation of browser hijackers?
