Has your web browser’s performance slowed down? Have you opened your browser only to find new and strange-looking icons, ads everywhere, a different homepage or search engine, without you doing or installing anything? Then your browser might have been hijacked! While it usually is a rather benign form of malware, it can turn into a big headache, compromise your computer or even ruin your life
What is a Browser Hijacker
Browser hijacking is a form of malware that messes with your browser and injects annoying advertising. They are able to override your browser’s settings without your permission. Aside from advertising they might also change your start/home page, search engine or even your error page in order to force you to generate traffic to those pages which translates to ad revenue for them. Another common tactic is to force redirect you to an unwanted site or page.
It most frequently comes in the form of a browser add-on. Some forms will produce annoying or inappropriate pop-up ads such as for pornography. They can also add such pages to your bookmarks. However it is not a computer virus and there is no such thing as a “hijack virus”.
Symptoms of Browser Hijacking
We have already mentioned a few unmistakable signs that your computer is hijacked.
If you want to find out for sure, look for these signs or the ones below:
- Home or start page has changed;
- Error page has changed;
- Ads fill my browser;
- New, unwanted browser extensions, toolbars or search bars;
- New, unwanted bookmarks;
- Pages load very slowly or not at all;
- Uncontrollable popup pages filled with ads;
- Unwanted redirection to web pages;
- If there is any item (extension, toolbar, page, etc.) that seems to have been added without your permission, start by searching the web for it and see if it is a known hijack.
Aside from being invaded by ads, a more insidious hijack is to redirect you to a different website or search results: you go to google.com to search for something and instead you get results from a different engine or site, usually with lots of ads everywhere.
Impacts and Threats
As mentioned, most of the impacts are rather benign compared to other malwares but quite annoying: sluggish browser performances, intrusive ads, a website is blocked due to hijack, unprompted webpage redirection, inability to use your chosen search engine or your favorite sites.
But some are much more dangerous. A sub-category of browser hijackers are more interested in your banking information or passwords and will install spyware, such as a keylogger, to try and steal your data. They might then try to sell your data or even blackmail you.
More serious versions of computer hijacking will lead to registry damages (in Windows) or to your browser downloading more malware.

How to Prevent Browser Hijacking
On a computer
So how can you avoid your computer getting hijacked? There are several safety precautions that you can take and that can almost guarantee you will never get hijacked (again).
First, install a reputed antivirus along with Malwarebytes. While you can find plenty excellent free Antivirus programs, paying premium for Malwarebytes is well worth it as it gives you real-time protection against malware, including hijacking.
The next step is to keep your programs up to date. This applies to all your IT devices and is unfortunately often overlooked. That way you make sure to never let anyone exploit a known software vulnerability that is easily fixed by a security patch.
The third step is also a golden rule on the internet: beware of what you download. Whether it is an email attachment, a torrent file or software, don’t download anything that is not from a completely trusted source. Be especially wary when installing free programs as these are often financially supported by ads, which means they can use confusing language during the installation process and trick you into installing a search bar or plugin along with the program you originally wanted. Make sure to take a few extra seconds to read carefully what the installing window is saying during the installation process.
The easiest thing you can do is only install apps via Google Play Store. While sometimes appealing, installing apps via third-party sources exposes you much more to malware. You also should go into your Play Store app menu and click on “Play Protect”. There you can turn “Scan device for security threats” on.
Also avoid going to risky websites and definitely install an antivirus app if you do. Remember that if a website starts showering you with notifications or pop-ups, a quick solution is to go to the “Site settings” of the Chrome’s menu. Under “Permissions” you can turn “Notifications” off.
The same security procedures apply here: beware of phishing emails, don’t install anything you aren’t sure of and avoid visiting at-risk webpages.
If you use Safari, it’s a good idea to block pop-up windows. Go to your Settings and find the Safari app. Enable “Block Pop-ups” in the “GENERAL” section.
Safety on the internet almost always comes down to two things: educate yourself on known security issues and take the time to implement the simple preventive measures. This is usually more than enough to protect you from most threats, as long as you are not spending your days downloading torrent files on shady websites.
If you ever get hijacked, don’t panic there is most likely a solution to fix it. Do a web search to find out whether it is a known hijack or not and then clean your device and reset your browser to the factory settings. More often than not you will be rid of the problem for good.
