Search.defaultredirect.com Browser Hijacker: A Removal Guide

Browser hijackers are a form of potentially unwanted programs (PUPs) designed to manipulate your browser’s settings without your consent. These malicious programs typically alter the default search engine, homepage, and new tab page, redirecting your web traffic to unwanted or suspicious websites.

The primary purpose of browser hijackers is to generate revenue through ads, tracking user activity, or promoting specific websites. They infiltrate systems by bundling with freeware, deceptive pop-ups, or malicious downloads. Once installed, they compromise system performance, expose users to privacy risks, and may lead to more severe cyber threats.

Unlike adware, which focuses solely on bombarding users with ads, browser hijackers actively modify browser configurations to control user activity online. This makes them more intrusive and potentially harmful.
