Homepage hijacks: how to restore your browser’s start page

Homepage hijacks are one of the oldest – and still most common – browser annoyances. You open your PC’s web browser expecting Google, Bing or your favourite start page, and instead you’re greeted by a strange search engine, or a page full of ads.

While modern browsers are better at blocking unwanted changes, hijackers have evolved too. They use a range of tactics to keep their homepage in place and hard to remove.

Let’s look at how homepage hijacks happen and the best way to fix them.

What causes homepage hijacks?

Homepage hijacks usually come from a few different sources.

Malicious extensions 

Extensions can override your homepage, search engine, or new‑tab page. Some hide themselves or reinstall after removal.

Malicious pop-ups and alerts

Fake system alerts can pop up while browsing (for example, “Your browser is outdated” or “Security threat detected!”). Clicking these alerts often prompts you to download a fix or a plugin that then causes the homepage hijack.

Software bundling

Software bundling is a very common method. Attackers bundle their malicious code into legitimate, often free software installers. During installation, attackers usually hide the malicious element behind “Advanced” or “Custom” installation settings. If you blindly click “Next” or “Accept” without reading, you unintentionally grant permission for the homepage change to take place.

How do I remove a homepage hijack?

Resetting your browser is usually the easiest way to remove a hijacked homepage. This method can resolve the issue quickly without deleting important browser data, such as bookmarks, browsing history, or saved passwords.

Here’s how to reset the three most common PC web browsers: Edge, Chrome and Firefox.

How to reset Microsoft Edge

To reset Microsoft Edge, first open the browser and then click on the three horizontal dots in the top right of the app. Next, select Settings from the menu that appears.

Now close and re-open Edge, and the default homepage should show instead of the hijacked version.

Re-activating extensions in Edge

When you reset Edge, you also turn off any active extensions. If there are any you want to continue using, you’ll need to turn them back on. To do this, type the following into the address bar in Edge

edge://extensions/

and then hit the Enter key.

This will take you to the extension page. Look at the listed items and reactivate any you need by clicking the toggle switch so it turns green.

chrome://extensions/

and then hit the Enter key.

If a web browser reset doesn’t work

If resetting your browser doesn’t fix the problem, a potentially unwanted program (PUP) or malware may be responsible.

Your best option is to run a full scan with your antivirus. If you still have issues, Malwarebytes is also worth a try. It’s very effective at detecting PUPs and malware. When first installed, it includes a 14‑day trial of the full software before switching to a free version.

The free version doesn’t offer real-time protection, so you need to run a scan manually whenever needed, and it will nag you to buy it. However, it can be a useful companion to your main antivirus and may help remove the cause of a homepage hijack.
