If Chrome’s homepage changed without your permission, first check whether the change affects the Home button or the page that opens at startup. Then review Chrome extensions and recently installed apps before resetting the browser. The change can be a sign of unwanted software, but it does not by itself prove that your device is infected.
First, identify which page changed
Chrome treats the homepage and startup page as separate settings. The homepage opens when you select the Home button; the startup page appears when you launch Chrome. They may be set to the same address, but changing one does not necessarily change the other. Google’s homepage and startup instructions explain both settings.
- Only the Home button opens the wrong page: check the homepage setting under Appearance.
- The wrong page appears when Chrome launches: check the On startup setting.
- Searches go to an unfamiliar search engine or pages redirect: review extensions and installed apps as well as the relevant Chrome settings.
On desktop, open Chrome’s More menu (the three-dot icon), select Settings, and inspect Appearance for the Home button and On startup for launch behavior. Set the page you want in the setting that actually changed.

An unexpected homepage, startup page, or search-engine change is a warning sign to investigate, not a diagnosis of malware. Google lists persistent setting changes, unwanted extensions or toolbars, and redirects among symptoms that can accompany unwanted software. The symptom alone does not establish which cause applies, and Google’s guidance does not rank these causes by frequency.

| Possible source | Where it is managed | What to check |
|---|---|---|
| Chrome setting | Chrome Settings | Whether the homepage or On startup address was changed directly. |
| Extension | Chrome’s extensions controls | Whether an unfamiliar or untrusted extension is changing browser settings. |
| Installed application | Your computer’s operating-system settings | Whether an app you did not intend to install is associated with the change. |
| Administrator policy | Your work or school’s device or network management | Whether settings are enforced on a managed Chromebook. |
If the page returns after you correct it, that persistence is a reason to check for an extension, an installed program, or administrator control rather than repeatedly changing the same setting.
Check for unwanted apps before resetting Chrome
Google recommends checking the computer for unwanted programs before resetting Chrome. Look for software you do not recognize or did not intend to install, and use the operating system’s normal uninstall process only for items you identify as unwanted. On Windows, inspect Installed apps; on Mac, inspect Applications and move unwanted or unrecognized items to Trash. If you are unsure what an item does, do not remove it solely because its name is unfamiliar.

Be wary of unsolicited pop-ups claiming your computer needs an urgent update or cleanup. Google advises against clicking suspicious download or update prompts; if you need software, get it from that program’s official website. Its unwanted ads, pop-ups, and malware guidance covers the symptoms and these computer checks.
Review Chrome extensions
Inspect your installed extensions and disable or remove ones you do not recognize or trust. Chrome’s developer guidance says extensions that change startup, homepage, or search settings on Windows and Mac must use the Settings Overrides API. Users are notified about those changes, and disabling the extension reverts the settings it changed. See the Chrome Web Store extensions quality guidelines FAQ.

After disabling a suspect extension, check the relevant homepage or startup setting again. If you keep an extension, make sure you trust it and understand the changes it makes; do not re-enable extensions automatically after troubleshooting.

If this is a work or school Chromebook
On a Chromebook used at work or school, a network administrator may control the homepage and startup settings. If Chrome will not let you change them, or the setting reappears under management, ask your administrator whether it is enforced. Google notes that users cannot change administrator-controlled homepage or startup settings themselves. Check Google’s guidance for managed Chromebooks.
Why permission matters
Google’s Unwanted Software Policy says software should not be installed silently without the user’s permission and that programs changing system settings should clearly explain what changed and how to undo it. Those principles help explain why an unexpected browser change deserves attention, but they do not identify the responsible program in any individual case.
