What are Nancontrast 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-up advertisements and Nancontrast notifications is the malignant origins of the latter. Normal pop-ups are offered for you to enable with a straightforward purpose – notify you about the fresh articles, discounts and so on. It is a useful thing to help your website to retain visitors and help the interested ones to have the best price.

Short summary of the Nancontrast.com pop-ups:

Nancontrast pop-up ads, as opposed, have a deal with unlegit sites. You will commonly observe the offer to enable them after a redirection from another page. Redirects are OK unless it throws you to such a dubious place. In this case, enabling push notifications is offered as the anti-DDoS check-up. Alternatively, the sites may deny showing you the contents unless you enable these push notifications. These requirements should already raise suspicion, as websites usually feature a less obscure anti-bot mechanism. Seeing this requirement should be the reason to close the website doubtlessly. 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.

Nancontrast push notification.

How does it work?

The majority of web browsers support enabling push notifications from websites. Sites, on the other hand, can send notifications with the content of their choice. It may be a promotion of the product or a page published on this website, as well as a promotion of the page of their partner. As a result, you may see the push notification from site X, but interacting with it will throw you to website Y – because a referral link to the latter was built in.

Scoundrels bear on this feature in their attempt to gain money through advertising. They trick victims into allowing the pop-ups, and after that just spread numerous promotions of other crooks they have a deal with. As you can suppose, no image-caring organisations will contract with fraudsters. All the Nancontrast popups you may see lead to other fraudulent sites. At some point, the same user can get into a trap of several pop-up spamming sites, and its browser will turn into a complete mess.

The promotions these rascals show are paid under the pay-per-view model. It usually provides a miserable pay for one view, but when you have hundreds of users and make it hundreds of times each day – that is a much more significant sum. Despite the majority of such banners giving no result at all, it may still bring all the parties a lot of money.

Are Nancontrast push notifications dangerous?

Yes, they are. Initially, they may look non-threatening – just a colourful pop-up that appears from time to time. However, the things this window promotes differ sharply from what you generally see in pop-up ads. Nancontrast.com site is controlled by fraudsters, who deliberately show hundreds of malicious ads in pop-ups. They also never follow any manners of advertising and can launch sporadic pop-up ads into a storm of promotions. For weak computers, that may be enough to make the system slower. But that is not all problems these push notifications carry.

As with any other thing that touches illegal ads, Nancontrast pop-ups don’t have legit deals to offer. Even when hackers make the banners similar to ones from Walmart or Amazon, the web page these ads will throw you to are completely different. And these pages can 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, Nancontrast pop-up notifications are not recommended to click on either, and the best solution is to disable them as soon as possible.

How to remove Nancontrast pop-ups?

Fortunately, Nancontrast pop-ups removal is pretty easy. They parasite in the browser and can’t hide themselves among system files. However, as I stated above, some pop-up advertisements may deliver malicious programs to your computer. It is nearly impossible to predict all cases, and manual attempts to remove malware is a poor idea. For that reason, after removing the source of 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-up notifications, but they still appeared. That may be a sign of malware activity. GridinSoft Anti-Malware will be the best both recovery and malware checkup purposes, because of its abilities of system recovery and multi-layer detection system.
