News-nubuyo.cc ads: what it is and how to remove it

Chrome and Edge can keep a small part running in the background so that sites can deliver notifications, and Windows shows them in its notification area. That is why messages from news-nubuyo.cc keep arriving with no browser window open.

The permission to send them was granted when someone clicked Allow on a prompt from that site, often disguised as a robot check or a video player. Closing the browser does not remove it; only the notification settings do.

Remove news-nubuyo.cc from the allowed sites and the background messages stop. You can also stop the browser from running in the background in its system settings, but the permission is the real fix.

If you only opened the page and closed it, nothing else is needed besides removing the permission from news-nubuyo.cc. If the page asked for card details, a phone number or a password and you entered them, act on that: call the bank to block the card, or change the password from another device.

If it offered a download, delete the file unopened, or uninstall it from Installed apps if you ran it, then run a full scan. If you called a number shown on the page, follow the steps for callers in this guide. Finally, remove the permission so that no more messages arrive.

News-nubuyo.cc is a push-notification spam site, a kind of adware. It earns money by showing desktop notifications, and each view, click or redirect pays whoever runs it. It is not something people usually choose; it arrives through a free download, a fake button or a misleading prompt.

News-nubuyo.cc does not encrypt files or take control of Windows, but its ads are sold to anyone, including scam operators, so they can lead to fake virus warnings and unwanted downloads. The steps in this guide remove it from Windows and from each browser.

There are two possible reasons. If it appears as desktop notifications, a browser on this PC was given permission to receive them from news-nubuyo.cc, usually through a misleading prompt. That permission stays until you remove it in the browser's site settings.

If it appears as tabs or redirects, an ad on a site you visit is opening it, or an extension or program on the PC is. Test a private window: if news-nubuyo.cc never appears there, an extension is the likely cause. The plan above covers each case.

Only in the browsers that allowed news-nubuyo.cc, but checking all of them takes a minute and is worth it. We saw the notifications in Chrome, Edge and Firefox. Chrome and Edge keep their notification lists under site settings, and Firefox under Privacy & Security > Permissions.

Remove news-nubuyo.cc and any other unfamiliar site from each list, then turn off new notification requests if you do not need them. Remember that every browser profile has its own list, so a second profile can keep the messages coming after you clean the first.

Compare them with the details in the table above. News-nubuyo.cc produces desktop notifications, and the clearest sign of it is notifications from news-nubuyo.cc. Other adware looks similar, so check the name of the sending site at the bottom of a notification, the address in the tab that opened, or the newest entries on the extensions page.

If those match, this guide fits. If you see a different name, the same kind of steps apply, but remove the item you actually find rather than guessing.

Clicking Block is safe; it only tells the browser not to show notifications from that site. Clicking Allow is not dangerous to your files either, but it gives the site a channel to your desktop that spam sites abuse at once.

The prompt itself is part of the browser, so you can trust its buttons. What you cannot trust is the text on the page around it. If a page explains why you must click Allow, choose Block or close the tab.

Act quickly but calmly. Disconnect the PC from the internet first, so the connection ends. Uninstall the remote access tool they asked you to install and check Installed apps for anything else added during the call.

Run a Microsoft Defender full scan and offline scan. From another device, change your e-mail and banking passwords and sign out of all sessions.

If you paid by card, bank transfer or gift card, contact your bank or the card issuer immediately, and report the scam to the police. Do not answer if they call back.

Because the source may not be a file a scanner looks for. Browser notifications are a permission stored in the browser, and many adware extensions are not flagged because they come from an official store.

Some ad-supported programs are only reported if you enable detection of potentially unwanted apps. So a clean scan does not mean the job is done. Check each browser's notification permissions and extension list by hand, and turn on Potentially unwanted app blocking in Windows Security before scanning again.

No program removes News-nubuyo.cc itself, because there is nothing on the PC to remove: the notifications come through a permission saved in the browser, and only the browser's settings take it away, as the steps above show.

What Fortect can do is check the rest of Windows. Its free scan looks for malware, unwanted programs and damaged system files, which is useful if you clicked the ads, downloaded something from the pages they opened, or are not sure what else changed on the PC.

If the scan finds nothing and the notifications stopped after you removed the permission, this problem is solved. Use Microsoft Defender as a second opinion whenever you have downloaded files from pages like these.
