Google Chrome blocks automatic pop-ups by default, but settings can change over time or specific sites may be granted exceptions. If you are seeing unwanted windows, it is often a matter of refining your permissions or identifying whether the "pop-up" is actually a browser notification or malware.
Quick Steps to Block Pop-Ups
If you want to ensure your blocker is active, follow these steps:
- Access Settings: Go to Settings → Privacy and security → Site settings.
- Find Pop-ups: Click on Pop-ups and redirects.
- Set the Default: Select the option: "Don't allow sites to send pop-ups or use redirects."
- Clean Up Exceptions: Scroll down to "Allowed to send pop-ups and use redirects." Remove any sites you no longer trust.
Pop-Ups vs. Notifications: What’s the Difference?
Many users confuse pop-ups with notifications. Because they look similar, you might try to fix the wrong setting.
- Pop-ups: These are new browser windows or tabs that open automatically. These are handled in the Pop-ups and redirects menu.
- Notifications: These are system-style alerts that slide into the corner of your screen (even when Chrome is closed). These are handled in Site settings → Notifications.
Why Am I Still Seeing Pop-Ups?
If your settings are correct but windows keep appearing, one of these four things is likely happening:
1. Site Exceptions
You may have accidentally allowed a specific site to bypass the blocker in the past. Check your "Allowed" list in settings and delete any unfamiliar URLs.
2. Malicious Extensions
Some browser extensions act as "adware," forcing new tabs to open regardless of your settings.
- Go to chrome://extensions and disable anything you don't recognize.
3. Page Overlays
Not every "pop-up" is a new window. Some sites use overlays (HTML elements that cover the content of the current page). Chrome's pop-up blocker cannot stop these because they are part of the website itself. The only solution is to close the overlay manually or use a dedicated ad-blocking extension.
4. Malware or Adware
If pop-ups appear on every website you visit—or even when the browser is closed—your device may be infected.
- Run Chrome's Safety Check (Settings → Privacy and security).
- Perform a full system scan using your operating system's trusted security software.
How to Handle Deceptive "Virus" Alerts
If a pop-up claims your computer is infected, provides a countdown timer, or asks you to call a support number: do not interact with it.
- Do not click "Scan" or "Fix."
- Do not enter your credentials.
- Close the tab immediately. If the page freezes your browser, force-quit Chrome via Task Manager (Windows) or Activity Monitor (Mac).

Common questions
Frequently Asked Questions
Is Chrome’s pop-up blocker on by default?
Yes. Chrome is designed to block automatic pop-ups out of the box.
Why do I still see ads after blocking pop-ups?
The pop-up blocker only stops new windows from opening. It does not block banner ads, video ads embedded in a page, or site overlays.
Do I need a third-party pop-up blocker extension?
For most users, Chrome's built-in tools are sufficient. Only install an extension if you need advanced filtering (like blocking specific page elements), and always check the developer's reputation first.
What if pop-ups appear when Chrome is closed?
This is a sign of either OS-level notifications or malware. Check your system notification settings and run a malware scan on your device.
