Browser hijackers are a type of malicious software designed to compromise and manipulate web browsers. Their primary objective is to alter a user’s web browsing experience without consent, often leading to unwanted redirections, advertisements, and potentially harmful changes to browser settings. Unlike adware, which mainly focuses on delivering unsolicited advertisements, browser hijackers take control of the browser’s functionalities, such as homepage settings, new tab pages, and search engines.
Purpose and Threat of Browser Hijackers
The primary purpose of browser hijackers is to redirect users to specific websites or search engines, often for commercial gain. These websites may generate revenue through pay-per-click schemes or promote dubious products and services. Browser hijackers can infiltrate systems through various methods, including bundled software installations, deceptive ads, and phishing schemes. Once installed, they pose significant threats to the infected system and its user.
The threats include:
- Compromised Security: Browser hijackers can weaken system security, making it more vulnerable to other types of malware.
- Privacy Risks: They may track browsing habits and personal information, leading to privacy breaches.
- Performance Issues: These hijackers can slow down the browser and overall system performance, causing frustration and reduced productivity.
Browser Hijackers vs. Adware
While both adware and browser hijackers can deliver unwanted advertisements, their behaviors differ significantly. Adware primarily focuses on generating revenue through ads and may not necessarily alter browser settings. In contrast, browser hijackers actively manipulate browser configurations, such as changing the homepage or default search engine, often leading to a more intrusive and disruptive user experience.
SearchPlus Browser Hijacker
One prominent browser hijacker is the SearchPlus hijacker. It is known for its invasive tactics and impact on users’ browsing activities. SearchPlus typically installs itself on a system through deceptive software bundling or misleading downloads.
How SearchPlus Functions
- Installation: SearchPlus usually arrives on a system bundled with legitimate software. Users may inadvertently install it by agreeing to the default installation settings of a seemingly benign program.
- Behavior: Once installed, SearchPlus changes the browser’s homepage and default search engine to its own domain. It may also inject advertisements and redirect users to various promoted websites.
Detrimental Consequences
The presence of SearchPlus can severely impact your browsing experience. Users may find their browser’s performance degraded and experience frequent redirections to unwanted sites. This hijacker can also compromise user privacy by tracking browsing habits and potentially harvesting personal information.

If you run a system scan and encounter any of these detection names, it is essential to take immediate action.
