Spam Popups in Windows 10 Notifications

A user reported that weird popups appear at random times in the lower right corner of her Windows 10 Enterprise desktop. Malwarebytes found no infection. From her browsing history, I see that she visited, then “Documents Converter” in the Chrome Web Store, but there are no related plugins installed in Chrome. So where are these popups coming from?

She sent me this screen shot of a popup:

Spam popup 1

So it’s definitely from, but Chrome isn’t even running.

Then today when I logged on, before I started Chrome, I saw this as a native Windows notification:

Oh, I get it now:  Chrome is authorized to use Windows 10 native notifications. That’s not bad in itself, but I do wonder how it makes the popup “stick”—most Windows notifications disappear after a few seconds.

One way to temporarily hide the popup is to click on the notification icon (with the small “2” in the first screenshot above) to open all notifications in a sidebar, click Clear all notifications, then click outside the sidebar to close it.

You could disable all Windows 10 notifications from Chrome by pasting this into Chrome and choosing Disable:


But what we really want to do is disable notifications from the In Chrome, go to Settings > Advanced > Site Settings > Notifications, or just put this in the address bar:


If you click on the small right-arrow next to here, you’ll see its permissions. Click on Clear Data and Reset permissions:

Now when you go back to the main Notifications list, you should find that has been removed from the list.

For good measure, I decided to go to and explicitly block its notifications:

Spam popup 5

That page offers to take you to their Chrome web store app:

where I used the Report abuse link to say, “, which leads to this app, hijacks notifications for spam popups.“

    I hate the fact that Chrome is allowed to intrude your space with Windows notifications. I just turn on Focus Assist as a quick fix, but then I don’t get potential windows notifications that I might want.

    @Jason, haven’t seen this kind of spam since I wrote this. I do find one Chrome notification helpful in the Windows notification tab, when I get a Google Voice text message. If you don’t want any Chrome notifications, try going to chrome://flags/#enable-native-notifications and choosing Disable.

    Mark – thanks for posting this. I just had the same issue on a windows machine, from “” Your instructions allowed me to clear it all up.

    Appreciate this post. I followed it step by step, as I was receiving notification of ads and spam from
    It was found in the allowed websites.
    It worked, and removed all the notifications automatically.
    Thank you.

    Thanks for this, nice and simple (“In Chrome, go to Settings > Advanced > Site Settings > Notifications, or just put this in the address bar:

    chrome://settings/content/notifications” – scrolled down, found the bugger. Dealt with it)
