Already Asked Question on Fake McAffee Pop Up, but It's Still Happening

Daffy,

Though EmilyS726, has already provided most of the details you need for managing these website Push Notifications and tried to explain them, I'll just add some background and provide the official Microsoft page for managing them as additional information.

When I was trying to answer someone else's questions about these notifications, I fouind this old history article about them that explains where they came from (Google), why they exist and when Microsoft and Apple added them to their own browser, which for Microsoft was likely when they began using the Google supported Chromium Open-source browser as the base for their new Edge browser.

So as usual, we have Google to thank for these intrusive advertising popups used by websites, while Apple and Microsoft came along for the ride in order to provide similar support in their own browsers, in Microsoft's case due to the fact they're using the same core browser.

In a deeper sense, these particular popup notifications undoubtedly also use the Toast Notifications interface that Microsoft included in Windows over a decade ago that allows the display of such messages by apps that aren't currently open, which the Website Push Notifications are also able to do. Though it's a technical page, those Toast Notifications are discussed at this Microsoft page and you'll easily see the similarity of the one displayed there to the Website Push Notifications you're receiving.

You'll note that some others have posted in your thread about 'rouge' applications or browser extensions displaying popups, which though possible are far less common nowadays due to the fact that Website Push Notifications are displayed by Windows itself once you initially press the "allow" button on an initial; popup that's displayed, meaning they aren't malware as such won't ever be detected by any antivirus or similar security app as malicious. That's why the malicious advertisers love them, since they're just an HTML popup and won't be automatically blocked for you if you press the Allow button by mistake, as many people do.

Though that last image in your first post looks like it might not be a notification popup. I suspect that it was simply launched separately by the other 'Scan in Progress' Website Push Notification' popup that clearly is due to the website and OK button displayed first.

Yes, the combinations here can be complex, but that's the point, since the last thing the malicious advertisers want is for any of this to be easy or seem obvious to allow you to fix the annoying popups without contacting them, so they can either sell you something or steal your personal information or identity, which is often their true goal.

Hello Daffy,

Based on your screenshots and descriptions, I don't think these are "notifications". They are pop ups particularly related to those two sites.

Scammers use various methods to trigger these pop-ups. Pop-ups are a form of online advertising. They are often integrated into websites or applications through ad services. Many websites (including legitimate websites) use third-party advertising services to display ads. Sometimes, these ad services might inadvertently allow scam ads to be displayed. This does not mean the website itself is malicious or the pop up is malicious, but it indicates a lack of stringent ad vetting. The ads content is trying to create a non-existing issue to get you to react and engage, then you might end up contacting whatever website they will take you to in order to contact them once you engage, once contacting them, they will scam you.

That said, on Edge, use this setting link to launch the settings related to popups:

edge://settings/content/popups?search=pop

You can turn on the master toggle to disable all popups.

OR, you can turn off the master toggle, but then make sure you add those two websites you experienced the pop up in the "block" section. Not necessary the https://tnmc6xr71o.sbs:443 site as that's the popup direct site. But the actual two websites you said where the popup happened.
