Is Setonna.com ads dangerous?

Setonna.com hopes you will click the "Allow" button without thinking
Setonna.com is a bogus website that relies on people clicking the "Allow" button to give permission for push notifications to show up on their screen.
A friendly-looking robot is displayed on the page with a message "Click "Allow" if you are not a robot". In the corner of the screen, there is an E-CAPTCHA writing with a logo. It is clear that the website wants to mislead people into thinking they are just performing a standard procedure by confirming they are human and not a bot.
This is done in order to get you to subscribe to push notifications and then spam you with pop-up ads. The worrying part is, the authors of the page do not care about user privacy or security so they do not blacklist fishy advertisements.
Some of the links embedded in the notification prompts can lead to questionable websites where users can be taken advantage of and be tricked into providing their personal information or installing potentially unwanted programs and even malware.

The appearance of pop-up spam is often confused with a virus infection
Because pop-up ads appear suddenly and seemingly out of nowhere, many people think that they have been infected with a computer virus.
That is not true in most cases, as push notifications are based on a subscription model, only users themselves can allow them. Of course, there are cases of adware infections that cause pop-ups, but besides that, users experience other symptoms too, like redirects and an increased amount of commercial content like banners, surveys, etc.
Besides having to "confirm that you are not a robot" you might also see messages saying:
Payouts from the pay-per-click advertising model, keep these individuals motivated to come up with new ways to fool users, so you should never let your guard down.
It is important to learn how you got here in the first place, to avoid this issue in the future. The truth is, that usually, people do not find websites like Setonna.com in their search results. You were probably surfing through already shady pages filled with deceptive ads and sneaky redirects.
It is a common misconception that the Internet is a completely safe space and viruses are a thing of the past. But it is actually the opposite - online fraudster and cybercriminals activity has been on the rise especially since the pandemic started.
You should not go clicking on random links and buttons. There are never too many precautionary steps you can take. As we said before, sometimes pop-up ads can be caused by adware and that happens when people install freeware from unofficial sources.
People rush through the installation process because they think there is nothing to see there and they find it exhausting. However, you should pay attention if you do not want bigger problems in the future.
Social engineering techniques are common among online fraudsters. They prey on not very tech-savvy people and try to use human vulnerabilities against them. Fake software updates, giveaways, paid surveys, threat warnings can be often found on shady sites that are unregulated, and it is sad to say that still a big chink of people fall into the traps.

How to stop Setonna.com notifications
Do this in every browser you use, and in every profile inside it: each keeps its own list of sites allowed to send notifications.
Nothing has to be uninstalled for the notifications themselves.
Which browser shows the ads?
Step 1: Remove setonna.com from Chrome's notification list
Chrome keeps a list of every site you once allowed to send notifications, and
setonna.comis on it. Pastechrome://settings/content/notificationsinto the address bar, find setonna.com under Allowed to send notifications, open the three-dot menu next to it and pick Remove.Then click Add next to Not allowed to send notifications and type setonna.com, so the site cannot ask a second time. Repeat it in every Chrome profile you use on Windows 11 or Windows 10, since each profile has its own list.

setonna.comfrom the Allowed list, then click Add site next to Not allowed to send notifications and enter it there.Edge is built into both Windows 11 and Windows 10, so check it even if you normally use another browser. If the notifications came with the Edge logo, this is the browser that holds the permission.

- In the Applications folder, look for any suspicious entries, then drag them to Trash (or right-click and pick Move to Trash).

Delete leftover files and folders:
- Select Go > Go to Folder.
- Enter /Library/Application Support and remove any suspicious folders related to the unwanted program.

Step 2: Scan the PC if you downloaded anything from the ads
If you only saw the notifications and clicked nothing, you can stop before this step. If a notification led you to download or run something, delete that file, then scan Windows.

Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online.
One of the basic means to add a layer of security - choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features.
However, if you want true anonymity, we suggest you employ a powerful VPN - it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable.
Family photos, work documents, school projects - these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur:
- power cuts
- Blue Screen of Death errors
- hardware failures
- crypto-malware attack
- even accidental deletion
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, can be your only hope to retrieve your invaluable files.
Questions about Setonna.com ads
Why do I get notifications from setonna.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 setonna.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 setonna.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.
The setonna.com notification said my PC is infected. Is it true?
No. Notifications from setonna.com are adverts written to look like system messages. A website cannot scan your files, so it has no way to know whether your PC is infected; it shows the same warning to everyone who allowed its notifications. Real Windows Security messages name Windows Security in the bottom line, not a browser and a website.
If you want to be sure, open Windows Security from the Start menu and run a quick scan there. Then remove setonna.com from the browser's notification settings so the fake warnings stop arriving. Do not call any number or buy anything the notification or its page suggests.
Why does Setonna.com show me ads?
Because that is its whole purpose. Setonna.com is a push-notification spam site, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of desktop notifications.
They are chosen by ad networks that accept almost any advertiser, which is why so many look like warnings or prizes. The ads are not a sign that your PC is broken or infected with something worse; they are a sign that something on it, or in the browser, has permission to advertise. Removing that permission or program stops them.
Is setonna.com safe to visit?
No. The site setonna.com exists to push visitors towards ads, and the pages it leads to include fake virus warnings, fake updates, prize scams and notification prompts. Visiting it once does not infect an up-to-date PC, but anything you click or download there is a gamble.
Do not enter personal details, do not allow notifications and do not call phone numbers it shows. If it opens by itself, close the tab and check the browser's extensions and notification permissions. Blocking the single domain helps little, because the operators register new names regularly.
Which browser is sending the setonna.com notifications?
Each notification shows the name of the browser and the site in its small print. In the cases we saw, the messages from setonna.com came through Chrome, Edge and Firefox. Permissions are stored per browser and per profile, so removing the site in one browser does not affect another.
If you use several Chrome or Edge profiles, check each one. If you sync the browser with an account, remove the permission while signed in, otherwise another computer may still hold it and keep receiving the same messages.
How do I know the ads come from Setonna.com?
Look for notifications from setonna.com. That is the trace Setonna.com leaves, and it shows up as desktop notifications. Ads that appear on every site, including ones that never carried ads before, point to something on your PC or in the browser rather than to the sites themselves.
A quick test is a private window, where extensions are off by default: if the ads disappear there, an extension is responsible. If they appear even with the browser closed, the source is a notification permission or a program in Windows.
Will Focus or Do not disturb stop the notifications?
Only for as long as it is on. Do not disturb in Windows 11 holds back notifications from all apps, including browsers, and releases them to the notification centre later. The site still has permission and the messages still arrive.
Use the browser's notification settings to remove the site instead: once its permission is gone, it cannot send anything, whatever Windows is set to. Keep Do not disturb for what it is meant for, such as meetings, presentations and quiet hours.
Did clicking Allow install anything on my PC?
No. Allowing notifications stores a permission in the browser and nothing else. No file is downloaded and no program is added to Windows, which is also why antivirus scans find nothing. The risk comes later, from the notifications themselves: they lead to scam pages, fake updates and phishing forms.
Remove the permission in each browser where you allowed it. If you clicked a notification and downloaded something afterwards, delete that file and run a Microsoft Defender full scan and offline scan.
An ad showed a phone number and I called it. What now?
The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.
If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.
Will Fortect remove Setonna.com?
No program removes Setonna.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.
