Captchaverifier.top uses push notifications for spam purposes

Captchaverifier.top does not actually verify if the user is real (human) or fake (bot). It is a dubious website that uses social engineering techniques[1] to fool people into granting permission to be shown push notifications. These notifications do not benefit users like the latest news, updates, or other things; instead, it sends ads from various sources and acts as a middleman.
The creators generate revenue from every click.[2] The more ads, the better, so they do not filter advertisements. Users can be exposed to pop-up ads created by shady individuals for scam or PUP [3] and malicious software distribution purposes. It is a rare occasion for users to come to this website on their own. Usually, they get redirected by clicking on deceptive ads[4] while browsing through already questionable sites.
It is always good to know that browsing through random pages is not always safe. There are a lot of individuals who want to take advantage of others and make easy money. In this article, we will discuss the techniques these kinds of websites use and how to eliminate the problem.

Common tactics pages use to exploit internet users
The pop-up ads seem to appear out of nowhere, and users often think that they have been infected with a virus. But that is not true. The most common way that these spam pages are able to send ads is because people allowed it themselves. Authors of Captchaverifier.top and other websites use clever methods that trick not very tech-savvy people.
The page we are specifically writing about uses captcha verification process that users are familiar with. If they are rushing, they are likely to not think about it and not read the prompt in the browser, which is saying that the website wants to send push notifications.

The page looks friendly at first sight, and you would not think it has any bad intentions. You can see a robot with a pink heart in it which definitely does not ring alarm bells immediately. You can also come across other messages that are meant to reach the same goal. They could look something like this:
Click Allow to verify your age
Click Allow to watch the video
Download is ready. Click Allow to download your file
They can have still images and GIFs of loading screens to make them look trustworthy. But do not be fooled – legitimate sites do not need you to give them permission to display content or provide you with a download. After clicking the “Allow” button, users do not receive anything in return because there is no other content to explore. The most likely scenario is, they get redirected to another shady page or nothing at all.

Privacy concerns
Almost every website you visit uses cookies nowadays to track you. Your browsing behavior is not private – the purchases you make, websites you click on, your IP address are used to personalize your experience and show ads that better suit your interests. This can be a good thing and a bad thing. We know that the most common way to infect yourself with push notification spam is by clicking through questionable sites.
They can collect your data and sell it to third parties, after which they will not be responsible for what happens to it and how it will be used, so you should be wary of that. After you disable unwanted push notifications, we recommend taking care of your browsers. Eliminate the data suspicious websites could have collected about you. Additionally, cache clogs up your storage, so using FortectIntego will improve your machine's performance as well. Besides that, it can fix system errors and corrupted files.
If manual removal did not work, it is a PUA
The ad spam could be caused by adware, which is a potentially unwanted program installed in your machine you probably do not know about. It monetizes your browsing by generating ads on your screen. Use SpyHunterCombo Cleaner or MalwarebytesMalwarebytes professional security tools to scan your machine automatically. It should detect most PUAs and other malicious programs and remove them successfully with all their files.
