Yahoo search is usually set as your default without you choosing it
Yahoo often becomes your search engine because you installed software that changed your browser settings, or because a browser extension modified them without asking. When you open a new tab or search from the address bar, Yahoo appears instead of Google, Bing, or whatever you actually want. The fix depends on which browser you use, but the process is straightforward — you change one setting and Yahoo is gone.
This guide covers the three most common browsers: Chrome, Firefox, and Edge. If you use Safari on a Mac, the steps are similar but the menu names differ slightly. The goal is the same: find your search engine settings and swap Yahoo for something else.
Key Takeaways
- Yahoo becomes your default search engine through browser extensions, unwanted software installations, or settings changes you did not authorize.
- In Chrome, go to Settings > Search engine and change the default from Yahoo to Google, Bing, or another option.
- In Firefox, open Preferences > Search and select a different search engine from the dropdown menu.
- In Edge, go to Settings > Privacy and search and change your default search engine away from Yahoo.
- If Yahoo keeps coming back after you change it, uninstall browser extensions you do not recognize and run a malware scan.
Remove Yahoo from Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings from the menu. On the left side, click Search engine. You will see a list of search engines with one marked as "Default" — if that is Yahoo, click the three dots next to it and select Remove.
Now click the dropdown under "Search engine used in the address bar" and choose Google, Bing, DuckDuckGo, or whichever search engine you prefer. Chrome will immediately use that engine the next time you search. If Yahoo is not in the list at all, you are already set and do not need to do anything.
Remove Yahoo from Firefox
Open Firefox and click the three horizontal lines (the menu button) in the top right corner. Select Settings. On the left side, click Search. Under "Default Search Engine," you will see a dropdown menu showing your current choice. Click it and select Google, Bing, DuckDuckGo, or another option. Firefox switches immediately.
If you see Yahoo listed under "One-Click Search Engines" below the default option, you can click the X next to it to remove it entirely. This prevents Yahoo from appearing in your search suggestions.
Remove Yahoo from Edge
Open Edge and click the three horizontal dots in the top right corner. Select Settings. On the left side, click Privacy, search, and services. Scroll down to the "Search engine" section. Click the dropdown next to "Search engine used in the address bar" and choose Google, Bing, or another option instead of Yahoo.
Edge will use your new choice from that moment forward. If you want to remove Yahoo from the list of available search engines entirely, click the dropdown again and look for a settings icon or gear symbol next to Yahoo, then select Remove.
Check for browser extensions that reset your settings
If Yahoo keeps coming back as your default search engine even after you change it, a browser extension is probably resetting it. Open your browser's extension or add-on menu. In Chrome, click the three dots, go to More tools, then Extensions. In Firefox, click the menu button and select Add-ons and extensions. In Edge, click the three dots and select Extensions.
Look for extensions you do not recognize or remember installing. Common culprits have names like "Search Enhancer," "Web Assistant," "Shopping Helper," or anything with "Yahoo" in the name. Click the remove or delete button next to any suspicious extension. After you remove it, change your search engine setting again — it should stick this time.
Run a malware scan if Yahoo keeps returning
If Yahoo reappears even after you remove extensions, your computer may have unwanted software installed. Download and run Malwarebytes (free version available at malwarebytes.com) or use Windows Defender if you have a Windows computer. Open Windows Defender by typing "Windows Defender" in your search bar, click Virus and threat protection, then Scan options, and select Full scan. Let it run completely — this can take 30 minutes or longer.
Malwarebytes or Windows Defender will find and remove software that changes your browser settings without your permission. After the scan finishes and any threats are removed, restart your computer and change your search engine setting one more time. It should remain changed.
Prevent Yahoo from being installed in the future
When you download software, read the installation screen carefully. Many installers include a checkbox that says something like "Set Yahoo as your homepage" or "Install the Yahoo toolbar" — these boxes are usually already checked. Uncheck them before you click Next or Install. This prevents the software from changing your browser settings.
Be cautious with browser extensions. Only install extensions from the official Chrome Web Store, Firefox Add-ons, or Microsoft Edge Add-ons. Avoid extensions with very few reviews or ones that ask for unusual permissions. If an extension suddenly changes your search engine or homepage without you asking it to, remove it immediately.
Frequently Asked Questions
Why does Yahoo keep coming back as my search engine?
A browser extension or unwanted software is resetting your settings each time you change them. Check your extensions list for anything unfamiliar and remove it. If that does not work, run Malwarebytes or Windows Defender to scan for malware that modifies browser settings.
Can I remove Yahoo from the search engine list entirely?
Yes. In most browsers, you can click the three dots or settings icon next to Yahoo in your search engine list and select remove or delete. This prevents it from appearing as an option at all.
What search engine should I use instead of Yahoo?
Google is the most common choice and is set as default in most browsers. Bing is Microsoft's search engine and comes with Edge. DuckDuckGo is an option if you prefer a search engine that does not track your searches. Any of these can be set as your default in seconds.
Is it safe to download Malwarebytes?
Yes. Malwarebytes is a legitimate security company and the free version is safe to download from malwarebytes.com. Windows Defender, which comes built into Windows, is also safe and does not require downloading anything.
Do I need to uninstall Yahoo completely from my computer?
No. Changing your search engine setting removes Yahoo from your browser — that is all you need to do. You do not need to uninstall anything unless Yahoo appears as a separate program in your Programs list, which is rare.
