Understanding and Removing the Ukasee Browser Hijacker

Browser hijackers are a type of malware designed to alter a user’s web browser settings without their consent. The primary goal of these malicious programs is to generate revenue for their developers through advertising or other means. Browser hijackers typically infiltrate computers via bundled software, deceptive advertisements, or by exploiting vulnerabilities in the browser or operating system. Once installed, they can change the homepage, default search engine, and new tab settings, often redirecting users to unwanted or harmful websites. These changes can significantly impact the user’s browsing experience and pose a threat to their privacy and security. Unlike adware, which primarily focuses on displaying intrusive ads, browser hijackers take control of the browser to manipulate user activity and redirect traffic.
