What is a browser hijacker?
A browser hijacker changes your browser’s settings without your permission by replacing your homepage, search page, and error page with pages of their own. A browser hijacker redirects your internet activity in order to collect advertising revenue from you, as well as your personal and browsing data.
How does a browser hijacker work?
Browser hijackers often infect computers through malicious websites and software bundles, particularly browser toolbars. They can usually be removed using antivirus software, but that might not be enough to undo the damage done to the host computer. A system restore is recommended.
