What are Knuckledd push notifications?

As the pop-up definition goes, these are short and small advertisements that attract your attention to a product they promote. But the difference between regular pop-up ads and Knuckledd notifications is the malignant origins of the latter. Normal pop-ups are offered for you to enable with a benevolent purpose – notify you about the fresh publications, goods for sale and so on. It is an effective approach to help your site to retain visitors and help the interested users to have the best deal.

Brief description of the Knuckledd.com pop-up ads:

Knuckledd pop-ups, in contrast, are related to untrustworthy sites. You will generally observe the offer to turn them on after a redirection from another page. It’s OK to see redirects unless it throws you into such a questionable place. In this case, enabling push notifications is served as the anti-bot check-up. Alternatively, the sites may deny showing you the contents unless you turn on these pop-up advertisements. These demands should raise suspicion, as websites generally feature a more convenient anti-bot mechanism. Witnessing this demand is a reason to close the page right away. Sometimes, even when you click “Allow”, you will not see the website – the only page it has is a landing page with the offer to turn on the pop-up notifications.

Knuckledd push notification.

How does this work?

Most of web browsers support turning on pop-ups from sites. Websites, on the other hand, can send notifications with the content of their choice. It may be an advertisement of the product or a page posted on this particular site, or a promotion of the page of their partner. As a result, you may see the push notification from site X, but clicking it will throw you to website Y – because a link to that website was built in.

Crooks rely on this ability in their approach to earn money through advertising. They trick users into allowing them to show the banners, and after that just spread hundreds of ads of other crooks they contract with. As you can suppose, no normal organisations will have a business with fraudsters. All the Knuckledd notifications you may see lead to other untrustworthy sites. In some cases, the same user can get into a trap of several pop-up spamming websites, and its web browser will turn into a complete mess.

The promotions these rascals show are paid under the pay-per-view model. It generally provides a negligible pay for one person, but when you can send ads to hundreds of users and show them hundreds of ads every day – that is a much bigger sum. Despite the majority of these ads are ineffective, it can still give all the parties a lot of money.

Are Knuckledd pop-up notifications dangerous?

Yes, they are. At the surface, they can look non-threatening – just a blinking window that appears from time to time. However, the things this window promotes differ sharply from what you generally see in pop-up advertisements. Knuckledd.com site is ruled by fraudsters, who intentionally spread hundreds and thousands of malicious ads in pop-ups. They also don’t follow any common sense and can launch sporadic pop-up advertisements into a hurricane of ads. For weak computers, that may be enough to make the system slower. But troubles are not over at this point.

As any other thing that touches illegal advertising, Knuckledd pop-up notifications lack legit deals to offer. Even when hackers make the ads looking similar to ones from Amazon, Walmart or Ebay, the web page these banners will throw you to are completely different. And these pages may offer you to turn on other pop-ups, install a “useful” program, or pay for a thing at a big discount and never receive it. Let’s leave aside the cases when push notifications promote phishing pages or straightforward malware. There’s no way these pages will bring you any good, thus interacting with them is a very bad idea. For the same reason, Knuckledd pop-up ads are not recommended to click on either, and the best solution is to disable them as soon as possible.

How to remove Knuckledd pop-ups?

Fortunately, Knuckledd pop-up advertisements removal is not very complicated. They parasite in the browser and cannot hide themselves on a disk. Nevertheless, as I told above, some pop-up ads can deliver malware to your system. It is hard to describe all of the cases, and manual malware removal is a poor idea. Thus, after disabling the pop-ups the best option is to use anti-malware software. That is especially recommended in the case when you have never allowed pop-ups, and they still appeared. That can point at malicious software activity. GridinSoft Anti-Malware will be the best both system recovery and malware removal purposes, because of its abilities of system recovery and multi-layer detection system.
