This is usually a website’s request to send web push notifications, not a warning that your computer is infected. If it keeps returning after you choose No Thanks, block notifications for that site in your browser. If the window remains, it is probably a separate pop-up built into the webpage; clear that site’s data or troubleshoot the site’s stored settings.
What the message means
A website is asking you to subscribe to alerts that may appear outside the page—for example, in your desktop notification area. Publishers use them for news, updates, promotions, and other alerts. Notification services such as OneSignal let sites customize the prompt’s wording and buttons, so this phrase does not identify one particular website or service. OneSignal’s example prompt uses similar language.
Three different things can be involved:
- The site’s prompt: An in-page dialog or overlay designed by the publisher or its notification provider. Its text, appearance, and buttons are chosen by the site.
- The browser’s permission request: The browser’s own dialog asking whether that domain may send notifications. Choosing Allow in the site’s prompt may bring up this second request.
- The delivered notification: An alert sent later by an approved site and displayed through the browser and, depending on your device and settings, the operating system.
A custom prompt often has site branding, appears within the webpage, and uses buttons such as Allow and No Thanks. A browser permission request uses browser-controlled design and identifies the site asking for permission. Mozilla’s web-compatibility record documents a case where a site’s custom notification box behaved differently from Chrome’s native dialog; it was a specific site implementation, not evidence of a general Firefox fault. See the Mozilla issue record.

The request is not automatically malware. Many sites use push notifications for legitimate updates, but permission is not a guarantee that every future alert will be useful or trustworthy. A site could send unwanted advertising or links to misleading pages. Allow notifications only when you trust the site and actually want its alerts.

- Be wary if the prompt claims your device is infected, demands payment, impersonates an operating-system warning, or sends you to an unrelated domain.
- Do not confuse a notification opt-in with a download warning, antivirus alert, or ordinary browser pop-up. Each is a different kind of message.
- If an alert takes you to a suspicious download, payment page, or sign-in form, treat that destination as a separate security concern; do not enter information or download files just because the alert came through the browser.
Why it returns after “No Thanks”
No Thanks dismisses the site’s dialog, but the site must also remember that choice. If it does not save the response, the prompt can return. Other possible causes include:
- Cookies or local-storage data are blocked, cleared automatically, or partitioned.
- You are using private or incognito browsing, where site data may disappear when the session ends.
- A privacy extension, ad blocker, script blocker, or consent manager prevents the site from saving its choice.
- The prompt comes from a related domain or subdomain that has separate stored data or permissions.
- The site deliberately asks again after a delay, or its notification code has a defect.
- The site’s opt-out state is not shared across devices or browser profiles.
These are possibilities, not a diagnosis. A July 2018 AnandTech support thread recorded users seeing the prompt return across Safari, Brave, Android browsers, and multiple computers; some said clearing browser data helped, and the forum administrator said developers were addressing the issue. Those reports describe that historical incident, not every current prompt. Read the AnandTech thread.

Stop it in Chrome
In desktop Chrome, go to More (⋮) → Settings → Privacy and security → Site settings → Notifications. Under the relevant site, block or remove its permission. Chrome also offers quieter notification prompts, which reduce interruptions while retaining a control near the address bar. To prevent requests generally, choose the setting that blocks sites from sending notifications. Chrome’s notification help describes these controls.
You can also open the site, select the site-information icon to the left of the address bar, choose Site settings, and set Notifications to Block. This is usually the quickest option when you want to block just one site.

Blocking permission prevents that site from sending browser notifications. A custom in-page overlay may still appear because it is controlled separately by the website; if so, follow the steps under If the prompt keeps returning.
Stop it in Firefox
Firefox’s wording and layout can vary by release. The general route is Settings → Privacy & Security → Permissions → Notifications → Settings. Find the site and change its status to Block, remove it, or enable the option to block new notification requests. You can also use the site-information control beside the address bar to review permissions for the open site; the exact label and availability can differ by version.

The Mozilla issue linked above concerns a particular site’s custom notification box. It is useful evidence that a webpage overlay and a browser permission dialog are separate mechanisms, not a current Firefox settings guide.
Stop it in Safari on macOS
To change notification permission, open Safari → Settings → Websites → Notifications, then set the site to Deny or turn off the option that lets websites ask for permission. To remove the site’s saved response as well, open Safari → Settings → Privacy → Manage Website Data, search for the site, and remove its data if available. Removing data can sign you out or erase that site’s preferences.

These browsers generally provide both site-specific notification controls and a global default, but their menus are not necessarily identical to Chrome’s. Open the site-information icon beside the address bar and look for its notification permission, or search the browser’s settings for Notifications or Site settings. Block the individual site if you only want to stop that site; use the global setting if you do not want sites requesting notifications at all.
If the prompt keeps returning
- Block the notification permission first. Use the browser controls above. This is less disruptive than erasing all browsing data.
- Check the domain shown in the browser request. Block the domain that actually requested permission, and check the related page or subdomain displaying the overlay. Blocking pop-ups and redirects is not necessarily the same as blocking notification permission.
- Clear only that site’s data. Use the browser’s site-data controls to remove its cookies and stored data, then reload it. This may sign you out and reset preferences. Avoid clearing all browsing data unless you have a broader reason to do so.
- Test extensions briefly and narrowly. Temporarily disable a privacy, ad-blocking, or script-blocking extension for the affected site to see whether it is preventing the opt-out from being saved. Do not leave security protections disabled as a general fix; if an extension is responsible, adjust its site-specific settings.
- Try a clean browser profile. A new profile can help determine whether the issue comes from your existing settings or extensions. A private window is a less conclusive test: it may discard the refusal when the session closes.
- Use a content blocker only as a last resort. A site-specific rule may hide a custom overlay, but it can also break page controls. There is no universal filter rule for this wording because sites build their dialogs differently.
If the browser shows that notifications are blocked but the page still displays the prompt, the remaining element is likely the website’s own dialog or stored site state—not another browser permission request.

If you already clicked “Allow”
Revoke the site’s permission from the browser’s notification or site-settings controls above. If your operating system provides a separate notification control for the browser, review it there too. Clear the site’s stored data if the site’s own prompt or alerts persist after revoking permission. Do not click suspicious notification links; a download or credential request launched from one is a separate issue from the permission itself.
Quick Recap
Choosing the least disruptive fix
| Option | Best for | Trade-off |
|---|---|---|
| Choose No Thanks | A prompt that appears once | May not stop a broken or deliberately recurring prompt |
| Block one site’s notifications | Stopping alerts from a particular site | You will not receive wanted alerts from that site |
| Block notification requests globally | People who do not want web notifications | Sites cannot ask to send useful alerts |
| Use quieter notification prompts | Reducing interruptions while retaining browser controls | A notification control may remain visible |
| Clear one site’s data | Resetting a possibly stale or corrupted site choice | May sign you out and remove site preferences |
| Test an extension or a clean profile | Finding out whether your browser setup is involved | Testing takes time; disabling an extension temporarily reduces its protection |
| Hide the overlay with a content blocker | A persistent custom dialog that other steps do not remove | May break site functionality and requires a site-specific rule |
