Dfltsearch.com Browser Hijacker: A Guide to Understanding & Removing the Threat

Browser hijackers are a type of malware designed to alter a user’s web browser settings without permission. They often modify default search engines, homepages, and new tab pages to redirect users to unwanted websites. Unlike traditional adware, which primarily focuses on delivering advertisements, browser hijackers take over web browsers to control user traffic, which can lead to various forms of exploitation.

General Purpose and Infiltration

The primary purpose of browser hijackers is to generate revenue for their creators by redirecting web traffic to specific websites. They can infiltrate a computer through several methods, such as bundled software downloads, phishing emails, or malicious websites. Once installed, these hijackers typically modify browser settings to redirect users to affiliated websites or search engines.

Threats Posed by Browser Hijackers

For both the infected system and the individual user, browser hijackers pose significant threats. They can slow down the system, reduce browser performance, and introduce additional malware. For users, the risks include exposure to potentially dangerous websites, loss of personal information, and a compromised browsing experience.

Browser Hijackers vs. Adware

The primary difference between browser hijackers and adware lies in their behavior. While adware focuses on displaying intrusive advertisements, browser hijackers redirect users to specific sites, often bypassing user consent entirely. Browser hijackers typically make more substantial changes to browser settings and can be more challenging to remove than adware.
