What is browser hijacking?

Browser hijacking happens when unwanted software takes control of your web browser. It can change your homepage, default search engine, or install unwanted toolbars and extensions—often without your permission. The goal is usually to redirect you to specific websites, show you ads, or collect your browsing data. Hijackers can slow down your browser, compromise your privacy, and make it harder to use the internet normally. They often come bundled with free software downloads or through malicious websites.
