Browser hijackers are a form of malicious software designed to manipulate a user’s web browser settings without their consent. This type of malware can alter a browser’s homepage, search engine, and redirect users to unwanted websites. It often sneaks into systems bundled with free software, creating a silent but disruptive presence. The impact on users can be significant, as hijackers can cause excessive pop-up ads, alter browsing habits, and even lead to security breaches by redirecting users to phishing sites. Unlike adware, which primarily focuses on displaying ads, browser hijackers are more focused on redirecting users and often change default settings, such as the homepage or search engine, to generate revenue through unwanted traffic or even to collect sensitive data.
