about:blank is a browser URI for a blank page, not a regular website. It can appear briefly while a page opens, when a blank page is configured for startup or Home, or after a link or browser action does not navigate as expected. Seeing it by itself does not mean your device has a virus.
What is about:blank?
The about:blank address tells the browser to display a blank document; it is not a hostname or a normal webpage fetched from a named website. RFC 6694 defines the about URI scheme and says: “The "about:blank" URI refers to a resource represented in the browser by a blank page.”
In Chromium, each main frame and subframe begins with an initial about:blank document until its first document commits. That is why a tab or embedded frame may show a blank state briefly before its destination appears. A blank document can also be created deliberately or receive content, so the address alone does not guarantee that every such document stays empty. RFC 6694 · Chromium documentation on special-case URLs
Why do I see about:blank?
The cause depends on when it appears. Startup, the Home control, a particular link, and session restoration are separate triggers. In desktop Chrome, startup and Home have separate settings.

- At launch: Chrome may be configured to open
about:blank, or it may be restoring a previous browsing session. - After using Home: The Home button may be set to open a blank page.
- Briefly before a page loads: A new tab, popup, or frame may begin as an initial blank document before the destination loads.
- After one link or button: The site action may have opened a popup or attempted a navigation that was blocked or did not complete.
- With a real website address still in the bar: A white page at a site URL is a site loading or rendering problem, not the same thing as the browser displaying
about:blank.
How to stop it from opening in desktop Chrome
First note whether it appears at startup, after clicking Home, or only after a particular action. The setting to change depends on the trigger.
If it appears when Chrome starts
- Open Chrome and select the three-dot menu, then Settings.
- Select On startup.
- If Open a specific page or set of pages is selected, remove
about:blankfrom the list or choose Open the New Tab page.
If it appears after you select Home
- Open Settings, then Appearance.
- Check Show Home button and the page configured for it.
- Change the destination if it is set to
about:blank, or turn off the Home button if you do not use it.
These desktop Chrome paths are documented in About Blank’s Chrome settings guide. Other browsers may use different labels and controls.

If it follows a particular click
The startup and Home settings are unlikely to be the relevant controls if the blank page appears only after one site action. Check whether the browser blocked a popup. You can try the action once in a private window; do not retry if it could duplicate a payment or download. If the action works there, review site data and extensions in your normal profile.
What does about:blank#blocked mean?
about:blank#blocked is associated with Chromium’s blocked or rewritten navigation result. The suffix alone does not identify which rule or setting caused it. Retrace the action that opened the page and consider whether a popup rule, restricted target, extension, sandbox, or managed-browser policy is involved. It is a symptom to investigate, not a diagnosis or universal virus code. About Blank’s explanation of about:blank#blocked

Is about:blank a virus?
No. The about:blank page itself is not a virus, and it is not a security tool. A browser or security product may display a blank result after blocking an action, but the blank document does not scan, filter, or certify the destination.
Look for independent signs of a browser or device problem: homepage, startup, or search settings changing without permission; unknown extensions returning after removal; repeated ads, tabs, or redirects across unrelated sites; or a genuine operating-system security alert. If these persist, review extensions and browser settings, update the browser and operating system, and run a trusted security scan. If the device is managed by work or school, contact IT before changing managed settings. About Blank’s security guidance

How to tell which problem you have
| What you see | Likely interpretation | First step |
|---|---|---|
about:blank at launch |
A blank startup page or restored session | Check Chrome’s On startup setting. |
about:blank after using Home |
The Home control is configured to open a blank page | Check Appearance and the Home destination. |
about:blank after one click |
A popup or navigation tied to that action | Investigate the site action and popup behavior. |
about:blank#blocked |
A blocked or rewritten navigation result associated with Chromium | Trace the original action; inspect relevant site, extension, sandbox, or policy settings. |
| A white page with a website URL in the address bar | A site loading or rendering issue | Troubleshoot that website rather than changing about:blank settings. |
Created blank frames or popups can receive content and, depending on how they were created, inherit the creator document’s origin. Chromium documents that direct address-bar entry has an opaque origin, while a frame or popup created by another document can inherit its origin; MDN also describes origin inheritance for scripts in an about:blank document. The URL text alone is therefore not enough to make broad claims about a document’s security. MDN: Same-origin policy
