What are N.wigglewur pop-ups?

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-ups and N.wigglewur pop-ups is the malignant origins of the latter. Common push notifications are offered for you to enable with a straightforward purpose – notify you about the latest articles, goods for sale and so on. It is a useful tool to help your site to keep visitor’s attention and help the interested visitors to have the best deal.

Brief description of the N.wigglewurm.com pop-up ads:

N.wigglewur pop-ups, as opposed, are related to untrustworthy web pages. You will generally witness the offer to turn them on following the redirection from another website. There’s nothing bad in redirecting unless it throws you to such a questionable place. In this case, turning on pop-up advertisements is offered under the guise of the anti-bot check. In other cases, the web pages may refuse to show you the contents unless you enable these push notifications. These theses should already raise suspicion, as sites commonly feature a different anti-bot mechanism. Spectating this demand is a reason to close the site doubtlessly. In some cases, even after clicking “Allow”, you will not get to the site – it has only a landing page with the offer to turn on the pop-ups.

N.wigglewur push notification.

How does it work?

Most of web browsers support enabling push notifications from websites. Sites, on the other hand, can send notifications with the content they want. It can be an advertisement of the product published on this site, as well as an ad of the page of their partner. As a result, you may see the push notification from site X, but clicking it will redirect you to website Y – because a referral link to the latter was embedded.

Cyber burglars rely on this feature in their attempt to earn money through advertising. They trick victims into allowing them to show the banners, and then just spread hundreds of promotions of anyone they contract with. As you can suppose, no legit companies will contract with fraudsters. All the N.wigglewur push ads you can see lead to other fraudulent sites. In some cases, the same victim may get into a trap of several pop-up spamming web pages, and its browser will turn into a complete mess.

The ads these crooks show are paid under the pay-per-view model. It usually provides a negligible payment for one view, but when you have hundreds of users and show them hundreds of ads each day – that is a much bigger sum. Despite most of these banners are ineffective, it can still give all the parties a lot of profit.

Are N.wigglewur pop-up ads dangerous?

Yes, they are. At the surface, they may look harmless – just a blinking pop-up that appears a couple times in an hour. However, the contents of this window differ sharply from what you generally see in pop-up notifications. N.wigglewurm.com website is controlled by fraudsters, who intendedly spread hundreds and thousands of irrelevant ads in pop-ups. They also never follow any common sense and can launch sporadic pop-up advertisements into a storm of promotions. For weak systems, that may be enough to cause performance issues. But that is not all problems these pop-ups carry.

As any other thing that touches illegal ads, N.wigglewur pop-up notifications don’t have legit offers. Even when crooks make the ads looking similar to ones from Walmart or Amazon, the web page these ads 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 pop-up ads 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, N.wigglewur 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 N.wigglewur pop-ups?

Fortunately, N.wigglewur pop-up advertisements removal is pretty easy. They parasite in the web browser and can’t hide themselves on a disk. However, as I pointed out before, some pop-up advertisements can promote malware to your system. It is nearly impossible to describe all cases, and manual attempts to remove malware is inconvenient. Therefore, after disabling the pop-up ads it is recommended to use anti-malware software. I’d especially recommend that if you have never allowed pop-ups, but they still appeared. This situation can be a sign of malicious software activity. GridinSoft Anti-Malware will perfectly fit both recovery and malware removal purposes, thanks to its abilities of system recovery and multi-component detection system.
