Bundle Extension Hijacks Browsers
Bundle extension is the name of a browser extension, which can end up installed inside your favorite browser and is classified as potentially unwanted software or a browser hijacker.
Bundle extension, once installed inside whatever browser you use, will make a number of alterations to your browser and its default, without asking for explicit permission. Those changes can include changing your browser's default search engine with one that is fake and tracks your search queries, and changing your home page and the content of your new tabs.
Browser hijackers can also be the reason for bad redirects that send you off to malicious or potentially unsafe pages when you click links. The sum of all those behaviors makes the presence of browser hijackers on your system unwanted.
The usual methods of distribution used for this sort of application are a few. Browser hijackers can enter your system if you allow push notifications from misleading websites, install software bundles that have potentially unwanted programs bundled in them, or through following rogue links and ads that start the installation of the unwanted extension.
When it comes to browser hijackers, for the most part, removal is easy - all you need to do is navigate to your browser's extensions menu, find the unwanted extension and click "Remove".
