Stop Unwanted Website Notifications in Desktop Chrome
By ON Lab · Sources checked November 6, 2026
For unwanted website notifications on a computer, open Chrome Settings → Privacy and security → Site settings → Notifications. Use the blocked list to block the sender’s website address. A notification permission and a pop-up permission are different controls, so first identify which kind of interruption you are seeing.
Identify the sender before changing a setting
Our suggested first check is to note the website address shown on the unwanted notification, if one is visible. A site name, an alert’s wording and a confirmed diagnosis are different things. Google warns that some sites claim a device has a virus to persuade people to download harmful software. An alarming message alone does not establish that its claim is true.
If you cannot identify a website sender, keep that uncertainty in your notes. This article does not establish that an alert from another app or the operating system came from Chrome.
Block a known website address in Settings
- Open Chrome’s three-dot menu and choose Settings.
- Choose Privacy and security → Site settings → Notifications.
- Beside Not allowed to send notifications, choose Add.
- Enter the sender’s website address and confirm with Add.
Google documents this route for desktop Chrome. Using Settings lets you enter a known address without following a link inside the notification. Check the address carefully so you do not change permission for a different site.
Check the saved result
As an editorial verification step, reopen the Notifications settings and read the blocked address in full. Compare it with the sender you recorded. If another alert appears, compare its sender too: a different domain is a different observation, and an alert without an identifiable sender remains unresolved.
For a trusted site you already have open, Google also documents using the control beside the address bar, choosing Site settings, and changing a permission. Site-specific choices override the default, and those changes save automatically.
If the problem is a new window or redirect
Chrome has a separate Site settings → Pop-ups and redirects page. Google notes that blocking pop-ups can still leave subscribed notifications, which is why changing only the pop-up control may miss the sender. Repeated unwanted windows, redirects or other persistent symptoms need their own investigation; a notification block is not proof of malware removal.
Scope: desktop Chrome website permissions, checked against Google’s documentation. We have not inspected your computer or tested a particular sender. This procedure does not diagnose infection or guarantee that all alerts stop.
