Many people are complaining that they have issues with a website known as Check-tl-ver-12-3.com. This site makes them accept notifications then sends them annoying ads either on their phones or computers.

We will expound on such website in detail, its operations as well as ways of removing the ads.

So what is Check-tl-ver-12-3.com?

It is a deceptive webpage. It shows false error messages through your browser which make you think that by clicking ‘Allow Notifications,’ you can fix something. Nevertheless once accessed, it floods your device with multiple pop-up ads that are irritating and offensive to its users. Some of these advertisements continue even if someone is not actively browsing the internet. Here’s one common way it deceives people:

What does this popup do?

• False Alerts for Notifications: This site tricks you into turning on push notifications with fake system warnings. For instance, it might falsely warn you that your browser is outdated and needs an update.
• Unwanted Ads: Once you enable notifications, the site bombards your device with inappropriate ads. These can vary from adult content and dating site promotions to fake software update scams and questionable products.
• Bypassing Pop-up Blockers: By deceiving you into accepting push notifications, Check-tl-ver-12-3.com can get around the pop-up blockers in your browser. This means it can send ads straight to your device, even if you have a pop-up blocker activated.

Why am I seeing these ads?

If you’re getting a lot of pop-up ads from Check-tl-ver-12-3.com, it’s probably because you accidentally turned on push notifications for the site. Here’s how they might have tricked you into doing this:

1. Fake Error Messages: The site shows fake warnings, making you think you must turn on notifications.

3. Unexpected Redirects: Sometimes, you might be taken to Check-tl-ver-12-3.com without meaning to, maybe from another site or a pop-up.
4. Software Downloads: Some free software could include Check-tl-ver-12-3.com in its installation package, setting up the notifications without you knowing.
