Browser hijackers, or simply hijackers, are a type of malware created for the purpose of modifying Internet browser settings without the user’s knowledge or consent. Typically, hijackers change the homepage and default search settings. Browser hijacker is an infection from the malicious software family. Technically, the browser hijacker is not a virus, but it does bad things – modifies the settings of your internet browser such as the Chrome, Firefox, IE and MS Edge.
Browser Hijackers are programmed for the benefit of cyber hackers. Through revenue generation as a result of forced ad clicks, website visits, or stealing bank / email authentication details from unsuspecting users. This is achieved by installing adware extension, search toolbar or keylogger software on the user’s browser. How Do They Get Installed? In most cases, these hijackers come bundled with another harmless software product. They are presented as a special offer or a bonus connected to a current installation, which looks confusing to an average user. Then he gets tricked into installing this unwanted piece of software.
Some browser hijackers may get installed through email attachments or torrent downloads. How Do Browser Hijackers Work? The main motive of a browser hijacker is to change the setting of a browser by overwriting the user’s choices. In other words, if the user’s choice for a default search engine is Google, the hijacker will force it go to Ask.com instead. Another common hijacker operation is to redirect you to the hijacker’s desired website. This might be a scam or phishing page asking you to enter personal details so they can steal them. Some browser hijackers may damage your registry on a Windows system.
And some of the more malicious browser hijacking programs will steal browser cookies on a person's computer in order to manipulate online accounts the user is logged into. Browser Hijacker Examples is a well-established browser hijacker that is installed with a toolbar. It steals confidential user data and sells it to third party companies. The toolbar is tagged as PUP / Adware by anti-malware programs. In another example, they also developed a program called Search Protect that claimed to protect browser settings, but actually enforced its own settings that infiltrated a user’s system. Coupon Saver is also considered a well-known browser hijacker that claims to help users with shopping by providing discounts and other good deals.
However, it just annoys the user’s browsing experience by showing intrusive ads and pop-ups. There are many more variations of hijackers presenting themselves as useful or “experience enhancing,” but are actually nothing more than a pain in real life. How to Remove Browser Hijackers As I said earlier, browser hijackers don’t come with clear instructions on how to uninstall them. They are difficult to remove because you cannot trace their installation path. Keep an eye on checkboxes while installing any software. You may be tricked into installing unwanted software programs by opting in during the software installation process. They are generally checked by default, and users have a mindset of proceeding without knowing the risks.
There is also a small tool called that can automatically uncheck any unrelated offer or software installation. Carefully read your end user license agreement (EULA) documents when installing software.
Oftentimes, mentions of browser hijackware are hidden in the EULA, so when you accept the user agreements, you might be unknowingly accepting malware as well. Be cautious when you install free programs. The old expression “there is no such thing as a free lunch” applies to software products too. Vendors often hide something inside the “free” program to earn money off of you.
Install MalwareFox and keep real time protection enabled. It constantly looks out for any suspicious programs and prevents the installation of hijackers.
A browser hijacker is defined as a “form of unwanted software that modifies a web browser’s settings without the user’s permission.” The result is the placement of unwanted advertising into the browser, and possibly the replacement of an existing home page or search page with the hijacker page. The idea is to make users visit certain websites whether they want to or not so the hijacker enjoys higher advertising revenue. Browser hijackers may also contain spyware to obtain banking information and other sensitive data. As frustrating as browser hijackers can be, they luckily aren’t terribly challenging to remove—most of the time. Utilizing various software packages is therefore essential to keep hijackers away. How Browser Hijackers Infect Computers Browser hijackers infect computers by numerous means, including through shareware, freeware, and advertisement support applications “deployed through the installation of a web browser toolbar or add-on.” Adware and spyware infections also result in browser hijackers, as does exploitation of various browser vulnerabilities.

Additional Options Sometimes the Power Eraser or a similar option doesn’t remove the toolbars, meaning they must be removed manually.
This is done by resetting browser settings to remove unnecessary toolbars and search engines entirely.
