How To Tell If Your Web Browser Has Been Hijacked

Image Created with Meta.AI

Have you ever noticed your web browser behaving strangely, with unfamiliar toolbars or search engines suddenly appearing? You might be a victim of browser hijacking, a sneaky form of malware that takes control of your browser and can compromise your online security. Browser hijacking can lead to a range of problems, from annoying ads and redirects to serious threats like data theft and identity fraud. Here's what you need to know:

The most obvious red flag of web browser hijacking is when your homepage or default search engine changes without your consent. If you unexpectedly find yourself searching through an unfamiliar search engine, or your start page becomes something new or strange, it’s often because your browser has been hijacked.

Other things to look out for are malicious browsers and browser hijackers like Ask Toolbar, Baidu Browser Hijacker, and Delta Search can wreak havoc on your online experience. These rogue browsers often sneak onto your device bundled with other software or through deceptive downloads. Once installed, they can alter your browser settings, redirect your searches, and bombard you with unwanted ads. Some, like SearchProtect and QSearch, can be particularly stubborn, making them difficult to remove and posing significant risks to your online security and personal data.

Web browser hijacks don’t arrive through a “hack” in the traditional sense—they come bundled with free software or browser extensions. When you click through installation screens without reading, you can unintentionally agree to change your homepage, search engine, or install add-ons.

Malicious websites can also push fake updates or pop-ups saying you need a “security tool” that’s just adware that allows them to hijack your browser.

If you suspect something is not right with your web browser, do the following:

• Chrome/Edge: Go to Settings > On startup to check your homepage, and Search engine to verify your default.

• Firefox: Open Settings > Home for homepage, and Search to check your engine.

• Safari: Go to Safari > Settings > General for homepage and Search for default engine.

If you see something you didn’t set, change it back. Also, check Extensions/Add‑ons in each browser. Remove anything you don’t remember installing or haven’t used recently.

Most hijacks can be removed by uninstalling suspicious programs in your computer’s Apps/Programs list and by removing bad extensions.

If that doesn’t clear it up, try running an anti-malware scan to catch stubborn remnants. In some cases, the sophistication used in the hijack may require a seasoned technician to eradicate the mess completely.

How to Prevent Future Hijacking. When adding new programs to your computers and devices, stick to reputable software sources and always choose the “advanced” or “custom” install options so you can uncheck extra offers.  Now that you know what to look for, make it a habit to periodically review your browser settings. Also, keep your browser updated; hijackers often target older versions with known weaknesses.

Even if a browser hijack feels like a small nuisance, it can be a gateway to bigger cyber attacks. Redirecting your searches can lead you to malicious websites or expose you to more aggressive scams. At the very least, it keeps you from getting good search results when you are trying to research things.
