Top 7 Ways to Fix Unwant­ed Sites Open Auto­mat­i­cal­ly in Google Chrome

Pankil Shah

Chrome earns its reputation for being a user-friendly browser by giving you control over things like notifications, pop-ups, and tracking data. It's only natural that it might face a hiccup or a feature might stop working abruptly. However, you should fix the browser when it starts opening unwanted sites automatically.

How to Fix Unwanted Sites Open Automatically in Google Chrome

Mostly an adware or a malicious extension is responsible for hijacking Chrome. Thankfully, there are a few solutions you can try to fix the issue. We'll show you how to do that. Let's get started.

1. Run a Virus Scan on Your Computer

To be on the safe side, it's helpful to run a scan using the Microsoft Defender on your Windows 10 or Windows 11 PC. Also, you can use Malwarebytes to check if your PC or Mac is infected or not.

2. Use Chrome Malware Scanner

Sometimes, malware and virus infection are responsible for Chrome’s tab opening problem. For that, Chrome carries its own built-in malware scanner to remove any such nuisances. Here's how you can run it.

Step 1: Launch Chrome and go to Settings. Scroll all the way down to expand Advanced settings and go to the Clean up computer option.

Step 2: Click on the Find button to initiate a quick scan of your PC.

Find Harmful Software

Wait for the process to finish and Chrome will let you know if it finds any harmful apps or programs.

3. Check Extensions

Chrome is popular because of its extension support which is known to work seamlessly. However, some of them might not be updated often. Also, poorly built extensions can often cause problems and lead to nefarious code hijacking it to open sites automatically.

Thus, you can try removing any suspicious extensions in Chrome to see if it helps with the issue.

To remove extensions in Chrome, type chrome://extensions/ and press Enter. Look for the recently installed extensions or ones you no longer use and click on the Remove button to delete them.

Once deleted, restart Chrome to see if the issue is resolved now.

4. Clear Cookies

Most websites these days force you to enable cookies on your browser for a complete user experience. Unfortunately, while cookies are often considered harmless, they can sometimes carry hostile scripts, which can cause your browser to behave strangely. In such cases, you can try clearing out Cookies in Chrome to fix the issue. Here’s how.

To clear cookies on Chrome, press Ctrl + Shift + Delete to open the Clear browsing data menu. Now mark the checkboxes that read ‘Cookies and other site data’ and ‘Cached images and files.' Lastly, click on the Clear data button.

Restart Chrome and see if it is working normally now.

5. Block Pop-Ups

If Google Chrome keeps on opening unwanted sites for no reason, then you can try blocking pop-ups in Chrome. Here’s how.

Step 1: Open Google Chrome on your PC and use the three-dot menu icon in the top right to select Settings from the list.

Open Chrome Settings

Step 2: Switch to the Privacy and security tab on your left and click on the Site Settings option.

6. Disable Background Apps

Background processes and extensions in Chrome help provide important information even when Chrome is not running. But, at the same time, they can also be the reason behind Chrome opening tabs randomly. Thus, disabling them might fix the issue. Here’s how to do it.

Step 1: Open Google Chrome and navigate to Settings.

Step 2: Scroll down to expand the Advanced settings. Under System, toggle off the switch next to the ‘Continue running background apps when Google Chrome is closed’ option.

That’s it. Now restart Chrome and see if the issue is resolved now.

7. Reset or Reinstall Chrome

If other solutions don’t help, then you can try resetting Chrome to its default settings to overcome the issue. Doing this will purge all extensions, cache, and history on Chrome.

To reset Chrome, type in chrome://settings/reset in the address bar at the top and then press Enter. Under ‘Reset and clean up’, click on ‘Restore settings to their original defaults’.

On the confirmation pop-up box, click Reset Settings to confirm.

Resetting Chrome will delete browser cache and cookies, search engines, and pinned tabs.

If you want to go all-in, instead of resetting, you can choose to uninstall and reinstall Chrome. This will give you a fresh start and will also update Chrome in the process.

Block Unwanted Visitors

Unwanted sites opening in Chrome can easily ruin your browsing experience. Hopefully, the solutions above have been good enough to solve your problems for now and you're back at surfing the web with Chrome.
