Is Webnotificationservices.com ads dangerous?
From our report of May 2022 · not reviewed since
Webnotificationservices.com ads should never be clicked on - you may end up on malicious websites
Webnotificationservices.com ads might be an unexpected occurrence on your phone or the computer, although you are definitely not the only one surprised by them.
Many users have reported that they started seeing suspicious pop-ups showing up on their screens randomly, regardless of which websites they were visiting at the time. To make matters worse, these ad windows are shown at the top of all other apps running on the system at the time, making the activity intrusive.
If you are dealing with this situation, you must have enabled push notifications from Webnotificationservices.com sometime before. You might think that you have never done that, but the truth is that you were ticked by a fake message asking you to confirm you are not a robot, you are 18+, or that the browser doesn't allow video playback among other reasons.
Once the "Allow" button is clicked, users then permit that particular website to send requests via the browser API, , which then manifests as push notifications shown on the system level. This means that the activity is fully absent when the browser is fully turned off. However, that's not the correct way of removing Webnotificationservices.com ads.

What are push notifications and how do they differ from pop-up ads?
There is a lot of confusion surrounding the push notification feature, especially when it comes to desktop computers.
Initially, it was used by the system or other official programs only - it was originally prevalent on smartphones and similar devices. Sometime later, in 2014, Google first adapted the feature to be used within the browser environment, which allowed websites to ask users whether they wanted notifications to be enabled.
Once allowed, the push notifications can be shown at any time, as long as the browser is enabled - it does not matter which websites users are visiting or whether they are interacting with the browser in the first place. As long as Google Chrome, Mozilla Firefox, Safari, MS Edge, or another browser is running, the push notifications can be shown at any time.
Pop-up ads, on the other hand, are triggered by users accessing websites they are hosted on. In other cases, adware installed on the system can also initiate pop-up ads, which would look particularly similar to what the Webnotificationservices.com scam website is doing.

Taking care of adware and other infections
As mentioned, users who get redirected to suspicious websites might well be infected with adware or other malicious software.
We strongly recommend using security software to check your system for adware and malware. This is especially important if you spot suspicious activity (ads, redirects, random mouse movements, crashes, etc.) on your device or explore the malicious websites you were redirected to - clicked on links, installed programs.
After removing malicious software from your system, you should repair virus damage and clean your browsers with . While manually cleaning your browsers is not difficult, as we explain below, fixing malware damage might be.
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files.
More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
Questions about Webnotificationservices.com ads
Why do I get notifications from webnotificationservices.com when the browser is closed?
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 webnotificationservices.com 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 webnotificationservices.com 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.
I clicked a notification from webnotificationservices.com. What should I do?
If you only opened the page and closed it, nothing else is needed besides removing the permission from webnotificationservices.com. 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.
What is Webnotificationservices.com?
Webnotificationservices.com 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.
Webnotificationservices.com 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.
Why does webnotificationservices.com keep showing up?
There are two possible reasons. If it appears as desktop notifications, a browser on this PC was given permission to receive them from webnotificationservices.com, 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 webnotificationservices.com never appears there, an extension is the likely cause. The plan above covers each case.
Do I have to change settings in every browser?
Only in the browsers that allowed webnotificationservices.com, 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 webnotificationservices.com 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.
Are the pop-ups I see really from Webnotificationservices.com?
Compare them with the details in the table above. Webnotificationservices.com produces desktop notifications, and the clearest sign of it is notifications from webnotificationservices.com. 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.
Can an adware pop-up infect my PC just by appearing?
No. A pop-up, a notification or a new tab is only a web page or a message. It cannot run programs on Windows by itself, provided the browser and Windows are up to date. Infection needs a step from you:
- running a downloaded file
- installing an extension
- giving a stranger remote access
That is why scam pages work so hard to make you click. Close such pages with the tab's X or by closing the browser, not with buttons inside the page, which may start a download.
I let a "support technician" from an ad connect to my PC. What should I do?
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.
My scan found nothing, but the ads continue. Why?
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.
Will Fortect remove Webnotificationservices.com?
No program removes Webnotificationservices.com 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.
