Have you ever been startled by pop-up ads suddenly appearing in the bottom-right corner of your screen while using your computer? Even with your browser closed, fake virus alerts and ad notifications keep popping up. Antivirus scans don’t detect anything. What is causing these persistent ads?
Quick Summary
- Cause: Browser push notification permissions granted by accidentally clicking “Allow” on a website
- Chrome fix: Enter chrome://settings/content/notifications in the address bar and delete/block sites in the allow list
- Edge fix: Enter edge://settings/content/notifications in the address bar and remove/block sites in the allow list
- Block all requests: Enable “Use quieter messaging” or “Quiet notification requests” in your browser settings
It’s Not a Virus: Why Do These Ads Keep Appearing?
Ads popping up in the bottom-right corner of your screen or in your OS notification center are not malware infections. They are web push notifications triggered by your browser after accidentally clicking “Allow” on a website.
Once notification permission is granted, websites can continue sending messages in the background even when your browser is closed. These web push notifications differ from traditional browser pop-up windows.
It is like handing over a key allowing someone to post flyers at your front door. The fix is simple: open your browser settings and revoke notification permissions by blocking or removing the offending websites.

- Remove specific sites: Under “Allowed to send notifications,” click the three dots (⋮) next to any suspicious website and select “Block” or “Remove.”
