Browser hijacking is the modification of a web browser's settings. The term "hijacking" is used as the changes are performed without the user's permission. A browser hijacker may replace the existing home page, error page, or search page with its own. These are generally used to force hits to a particular website, increasing its advertising revenue.
Some browser hijacking can be easily reversed, while other instances may be difficult to reverse. Various software packages exist to prevent such modification.
The homepages that are set by hijackers are often search pages, and many of these programs are spyware programs that track personal data.
Most installers will give users the opportunity to accept or decline an offer to install a hijacker; however, the request to decline the offer is often ignored or presented in a very confusing manner. This is done for the sole reason of tricking users into installing excessive bloatware and malware.

Examples of hijackers
Babylon Toolbar is a browser hijacker that will change the browser homepage and set the default search engine to isearch.babylon.com. It is also a form of which displays advertisements, sponsored links, and spurious paid search results. The program will collect search terms from your search queries.
In 2011, the Cnet site Download.com started bundling the Babylon Toolbar with open-source packages such as Nmap. Gordon Lyon, the developer of Nmap, vented his anger online over the way the toolbar was tricked onto users. The vice-president of Download.com, Sean Murphy, released an apology: The bundling of this software was a mistake on our part and we apologize to the user and developer communities for the unrest it caused.
New Tab is a browser hijacker which will set the browser homepage and default search engine to binkiland.com. It is also a form of adware which displays advertisements, sponsored links, and spurious paid search results. The program will collect search terms from user search queries.
It installs a Windows Service and runs on Windows start up.
Conduit is a potentially dangerous browser virus which steals personal and confidential information from the user and transfers it to a third party. This toolbar has been identified as Potentially Unwanted Programs by Malwarebytes and is typically bundled with other free downloads. These toolbars modify the browser's default search engine, homepage, new tab page, and several other browser settings.
A program called "Conduit Search Protect", better known as "Search Protect by conduit", can cause severe system errors upon uninstallation. It claims to protect browser settings but actually blocks all attempts to manipulate a browser through the settings page; in other words, it makes sure the malicious settings remain unchanged. The uninstall program for Search Protect can cause Windows to be unbootable because the uninstall file not only removes its own files, but also all the boot files in the root of the C: drive. and leaves a BackGroundContainer.dll file in the start-up registry. Conduit is associated with malware, spyware, and adware, as victims of this hijacker have reported unwanted pop-up and in-text advertisements.
Victims of unwanted redirections to conduit.com have also reported that they have been attacked by phishing attempts and have received unwanted email spam, junk mail, other messages, and telephone calls from telemarketers. Some victims claim that the people claimed to be Apple, Microsoft, or their ISP, that personal information was used in some phone calls, and that some of the calls concerned their browsing habits and recent browsing history. Personal information used in phishing attempts may be associated with spyware. This hijacker virus is currently added to the official PowerISO download, and the Vuze version 18.104.22.168 update, for example.
[] () was one of the first browser hijackers. It redirected the existing home page to the rogue CWS search engine, with its results as sponsored links. With most antivirus and antispyware programs unable to properly remove this particular hijacker, a man named Merijn Bellekom developed a special tool called CWShredder specifically to remove this kind of hijacker. CoolWebSearch is a popular browser hijacker and is owned by fun web products.
Coupon Server is an adware program bundled with multiple apps that are downloaded from the Internet by users. This program may appear on PCs without a user's knowledge. Coupon Server may appear to be useful, but can be intrusive and display ads without users' permissions. Coupon Server is also considered as a malicious domain and browser hijack. It will hijack your Internet browser and forcibly lead a user to its homepage, which is disguised as a legitimate search engine to fool visitors and benefit its website. It will direct the browser to a suspicious domain, alter browser settings and finally take over the whole browser.
Delta Search and Claro Search
Delta and Claro are programs that each offer a free search engine and toolbar often bundled with free downloads. These browser hijackers will redirect all searches to their own engines, to gain revenue. Automated tools are able to remove Delta, Claro, and their files, but the changes to the homepage and default search engine have to be reverted manually.
The ad-triggering software called GoSave is being reported to cause user experience issues because of its intrusive characteristics. Starting with installation where the victim is not appropriately informed, all the way to the absence of clear authorization for inserting ads into visited pages on the Internet – this piece of potentially unwanted code should certainly be exterminated from a computer it succeeded to compromise. The software developers who choose a free-of-charge setup model for their startups often conceal a substantial fact from their to-be customers. They mainly do monetize intellectual effort from the beginning by opting into the inclusion of third-party applications in the installation package for their tools. This type of promotion is okay, basically, as long as one important condition is kept: the affiliated software should be safe and unobtrusive. In the case with the program known as GoSave, though, the above-mentioned provision is highly doubtful. The involvement of free file downloaders into the proliferation of said adware, which GoSave definitely is, has been noted by malware researchers since this infection first emerged. Apps like Quick-Downloader, SendMyWay, Olcinium Software and File Factory are being exploited to push the malign code in a not-so-transparent manner. To their credit, these utilities mention that the user is about to get an extra item as a result of the setup, but sadly enough notifications like that are rarely paid attention to. Such somewhat covert infiltration of this threat into a PC being an event that went through, its operation instantly grows more than perceptible. It adds a plugin or extension to whichever one of the prevalent web browsers is used. It’s currently compatible with Internet Explorer, Firefox and Chrome. Important to know, the name of the troublemaking add-on isn’t necessarily "GoSave" – it varies and might be GS Booster, GS Sustainer or something else.
Groovorio.com (you can also find it named as Groovorio browser virus) is an annoying browser hijacker, which is used for promoting websites and programs that are related to it. Groovorio.com installs into computer system as a browser extension and once it gets into your browser it can take over all the major settings of all browsers.
The mischievous browser hijacker istartsurf.com may replace the preferred search tools illegally. This infection travels bundled with third party applications and its installation may be silent. Due to this, computer users are usually surprised to discover the hijacker when they launch the affected Internet Explorer, Google Chrome or Mozilla Firefox browsers.
Jamenize.com is a browser hijacker that affects Mozilla Firefox and Google Chrome web browsers. This application enters your computer without your knowledge and modifies your browser settings. This browser hijacker changes your default homepage to Jamenize.com and even modifies New Tab settings to Jamenize as well.
Mixi.DJ offers a media player, but also a free toolbar and Conduit-based search engine, the toolbar being the one which they will prompt to add during installation. The toolbar is a new hijacker that alters a browser's homepage. It also adds itself to the computer's registry, creates strings in the memory, and changes the icon on Internet Explorer to a magnifying glass.
The main problem with MyStartSearch.com is that this browser hijacker might look like a genuine search provider, and some users may not even realize they are infected. However, one of the best ways to determine whether something is wrong or not, is to check for commercial advertisements and various pop-ups. The presence of an adware application you are not familiar with is the first sign that something might not be right. Hence, if you see a lot of pop-ups and other types of advertisements on your search results page, check whether your default search engine is MyStartSearch.com or not.
MyStart.Incredibar Search (Mystart Search IncrediBar, MyStart toolbar, MyStart Search, IncrediBar, IncrediBar Games-EN) is a very dangerous Internet browser hijacker, virus, and spyware that often comes embedded with many download applications and installers such as HyperCam. It is known to install itself into Firefox, Internet Explorer, Safari, and Google Chrome
Symptoms range from no symptoms at all (simple processor drainage) to complete system crashes so severe that the victim has to re-install their entire operating system.
MyStart uses browser helper objects (in this case search tools) and infects some users by installing MyStart search toolbar into their browser (Firefox is most vulnerable) which redirects internet users to MyStart’s websites, mystart.incredibar.com in particular. Some Internet users report that they are redirected for every search or webpage they visit.
If mystart is not removed:
- Your computer can become malformed and operate improperly.
- Your browser settings become corrupted and Internet usage is taken hostage by a constant redirection setting to drive-by-download websites, which can open the door for more infections, and overall cause a wide range of operating system related issues associated with Trojans.
- Computer accesses may become blocked or locked if not MyStart is not addressed, similar to the behaviour of ransomware.
- Most of your user-initiated browsing and search is redirected to MyStart-based websites while you're infected.
- High levels of CPU usage are due to MyStart processes, which can cause systems to crash or become malformed.
Removing Incredibar can be an extremely daunting task since there are countless different variations and most infected systems can expect to find undesirable Windows registry changes, browser configuration changes, and files with random strings that are installed into the user's local settings folders and depending on the user's operating system, its version, and even computer the location will vary from one PC to the next. In one version of Incredibar it appears to be a removable add-on, plug-in, or extension within web browsers; however, simply removing Incredibar via the inbuilt browser add-on removal process is not enough since the program has already combined registry and file installs of which re-installs itself upon a system or browser reboot.
A few virus and spyware removal applications such as Webroot Spysweeper, Eset NOD32, AdwCleaner, and Junkware Removal Tool are known to remove Mystart.Incredibar, but using these applications to do so will not revert the user to their default search engine.
Nation Zoom is a browser hijacker that changes a browser's home page to Nationzoom.com and default search provider to Search.yahoo.com.
Onewebsearch, referred to as the onewebsearch virus, or onewebsearch.com redirection virus is malware, categorized as a browser hijacker.

Searchassst, not unlike vosteran can have spyware links. It is highly recommended to redirect to another webpage through the address bar if you start on searchassist.
Review sites such as Cnet.com may recommend searchassist, but many users rate it poorly. Searchassist claims to be a legitimate search engine with great personal results, tempting victims of the hijack, making it one of the hardest hijacks to recognize because the image on search assist is very much like a google doodle.

The cause of it getting onto the homepage is unknown, and it is known for downloading malware onto the computer. It replaces the default homepage for no reason and without the user's permission.

Most new hijackers will not allow a user to change back to their home page through Internet Properties. Modern hijackers' settings will most likely return upon reboot, however, well-updated antispyware software will likely remove the hijacker. Some spyware scanners have a browser page restore function to set the user's homepage back to normal or alert them when their browser page has been changed. Manual removal is also a good choice to give the user a good understanding of what to do while reverting all changes. After you do this, you may want to check for left-overs. This way, if any part of the program was left uninstalled, you could delete it to ensure your safety.
Rogue security software
Some rogue security software will also hijack the start page generally displaying a message such as "WARNING! Your computer is infected with spyware!" to lead to an anti-spyware vendor's page. The start page will return to normal settings once the user buys their software. Programs such as WinFixer are known to hijack the user's start page and redirect it to the website.
Beginning features confused with browser hijackers
In 2006, EarthLink started redirecting mistyped domain names over to a search page. This was done by interpreting the error code NXDOMAIN at the server level. The announcement led to much negative feedback, and EarthLink offered services without this feature.
A major sector of companies related to browser hijacking, as well as other, aggressive and, in parts, malicious adware and spyware, has grown in Israel's high tech region and is known as Download Valley.
