How to remove Qtr Search

What is Qtr Search

Qtr Search refers to a type of browser hijacker, a form of potentially unwanted application (PUA) that modifies web browser settings without the user’s consent. It is designed to redirect internet searches and browsing activities to generate advertising revenue through forced visits to specific websites or displaying sponsored content. Browser hijackers like Qtr Search often change the default search engine, homepage, and new tab settings to direct users to their associated domains or search engines. Qtr Search changes the default search engine of the infected browsers to its own, often redirecting searches to Yahoo or other third-party search engines that may display altered search results filled with sponsored content. This redirection aims to boost traffic to specific sites, thereby generating advertising revenue for the creators of the hijacker. Qtr Search is capable of infecting a wide range of popular web browsers, including Google Chrome, Mozilla Firefox, Internet Explorer, Microsoft Edge, and Safari. It modifies browser settings such as the default search engine, homepage, and new tab page, significantly altering the user’s browsing experience. The hijacker also installs additional components that can prevent users from reverting these changes easily.
