Why Does My Browser Open to MSN? Fix It

If your web browser keeps opening to MSN (msn.com) instead of your preferred homepage or a blank tab, the cause is almost always a changed browser setting, a bundled program that altered your homepage, or a browser hijacker. You can fix it by checking your browser’s startup settings, resetting your homepage, and removing any suspicious extensions or programs.

Why MSN Keeps Appearing

MSN is Microsoft’s default homepage for its own products and services. When you install certain free software (like a PDF reader, download manager, or utility tool), the installer may offer to set MSN as your homepage and default search engine. If you click through the installation without unchecking those boxes, your browser changes without your explicit consent. In other cases, a browser extension or a piece of adware can override your settings. Less commonly, a malware infection can force your browser to open MSN repeatedly.

How to Change Your Homepage in Each Browser

The fix starts with setting your preferred homepage manually. The steps differ slightly by browser, but the general approach is the same: go to settings, find the “On startup” or “Homepage” section, and enter the URL you want.

Google Chrome: Click the three-dot menu â†’ Settings â†’ On startup. Choose “Open a specific page or set of pages” and click “Add a new page.” Enter your desired URL (e.g., google.com). Also, under Appearance, check if the “Show Home button” is enabled and set its URL.
Mozilla Firefox: Click the hamburger menu â†’ Settings â†’ Home. Under “New Windows and Tabs,” set the homepage and new tab page to your preferred URL. Under “Homepage and new windows,” choose “Custom URLs.”
Microsoft Edge: Click the three-dot menu â†’ Settings â†’ On startup. Select “Open a specific page or pages” and enter your URL. Also, under “Home button,” you can set what the home button opens.
Safari (Mac): Open Safari â†’ Preferences â†’ General. Set “Homepage” to your desired URL and choose “Homepage” in the “New windows open with” dropdown.

Check Your Default Search Engine

MSN often comes bundled with Bing as the default search engine. Even if you change your homepage, your searches might still route through Bing (which is MSN’s search engine). To verify, go to your browser’s search engine settings and make sure your preferred search engine (Google, DuckDuckGo, etc.) is selected. In Chrome, this is under Settings â†’ Search engine. In Firefox, it’s under Settings â†’ Search. In Edge, it’s under Settings â†’ Privacy, search, and services â†’ Address bar and search.

Remove Suspicious Extensions and Programs

Browser extensions can hijack your homepage and search settings. Review your installed extensions and remove any you don’t recognize or that you didn’t intentionally install. In Chrome, go to Settings â†’ Extensions. In Firefox, go to Settings â†’ Add-ons and themes. In Edge, go to Settings â†’ Extensions.

Also, check your installed programs list (Control Panel â†’ Programs and Features on Windows, or Applications on Mac) for any recently installed software that might have caused the change. If you find something suspicious, uninstall it. Be careful not to remove legitimate programs you actually use.

What to Do If It Keeps Coming Back

If you’ve changed your homepage and removed extensions but MSN still appears, the cause is likely a more persistent hijacker. Try these steps in order:

Reset your browser settings: This restores the browser to its default state, removing most hijackers. In Chrome, go to Settings â†’ Reset settings â†’ Restore settings to their original defaults. In Firefox, go to Help â†’ More Troubleshooting Information â†’ Refresh Firefox. In Edge, go to Settings â†’ Reset settings â†’ Restore settings to their default values.
Run a malware scan: Use Windows Security (built into Windows 10/11) or a reputable third-party antivirus to scan your system for adware or malware that might be forcing the redirect.
Check your system’s DNS settings: Some hijackers change your DNS server to redirect you to unwanted sites. Go to your network adapter’s IPv4 properties and ensure “Obtain DNS server address automatically” is selected.
Check the hosts file: On Windows, the hosts file (C:\Windows\System32\drivers\etc\hosts) can redirect specific domains. Open it with Notepad and verify there are no lines containing msn.com or other suspicious domains. If there are, delete them (but don’t alter any other lines).

How to Prevent This in the Future

Prevention is mostly about being careful during software installation. Always choose “Custom” or “Advanced” installation options instead of “Recommended” or “Express.” This shows you any extra offers, like changing your homepage or search engine. Uncheck any boxes that ask to set MSN or any other site as your homepage. Also, download software only from official websites or trusted sources, and avoid clicking on pop-up ads that claim your browser is “infected” or “outdated” â€” those often lead to adware.

Frequently Asked Questions

Why does my browser open MSN even after I changed the homepage?

This usually means a browser extension or a background program is overriding your settings. Follow the steps above to remove suspicious extensions, reset your browser, and run a malware scan.

Is MSN a virus?

No, MSN is a legitimate website owned by Microsoft. However, it can be set as your homepage by bundled software without your clear consent, which is why it feels like a hijack. In rare cases, malware can force-redirect you to MSN, but the site itself is not malicious.

How do I stop MSN from opening on startup in Edge?

In Edge, go to Settings â†’ On startup, and select “Open a specific page or pages.” Enter your preferred URL. Also, check the “Home button” settings under Appearance to ensure it doesn’t open MSN.

Can a phone browser also get hijacked to MSN?

Yes, on mobile browsers you can change the homepage in the browser’s settings, but it’s less common. On Android, some free apps may change your browser’s homepage. On iPhone, Safari doesn’t have a homepage, but the “Start Page” can be set in Settings â†’ Safari â†’ General â†’ Start Page.

Will resetting my browser delete my bookmarks and passwords?

Resetting your browser will disable extensions and restore default settings, but it typically keeps your bookmarks, history, and saved passwords. However, it’s always wise to back up your bookmarks before resetting, just in case.

What if the problem is on a work or school computer?

If your browser is managed by your organization, the IT department may have set MSN as the default homepage through group policy. In that case, you may not be able to change it yourself. Contact your IT support for assistance.
