What are Qr-captcha pop-up advertisements?

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 notifications and Qr-captcha notifications is the malicious origins of the latter. Normal pop-up advertisements are offered for you to enable with a legitimate purpose – keep you aware about the fresh articles, discounts and so on. It is a useful thing to help your site to keep visitors and help the interested users to have the best price.

Short summary of the Qr-captcha.com pop-up ads:

Qr-captcha pop-up ads, in contrast, have a deal with untrustworthy sites. You will commonly observe the proposition to turn them on after a redirection from another page. There’s nothing bad in redirecting unless they throw you into such a questionable place. In this case, turning on pop-up ads is served as the anti-DDoS check-up. Alternatively, the sites may deny showing you the contents unless you apply these push notifications. These theses should already be the red flag, as sites usually have a more convenient anti-bot mechanism. Seeing such an requirement should be the reason to skip the website doubtlessly. Sometimes, even after clicking “Allow”, you will not see the website – it has only a landing page with the offer to turn on the pop-up advertisements.

Qr-captcha push notification.

How does it work?

The majority of web browsers support enabling pop-ups from websites. Sites, on the other hand, can send notifications with the content they want. It may be a promotion of the product or a page published on this site, as well as an ad of the page of their partner. As a result, you can see the push notification from site X, but interacting with it will redirect you to website Y – because a link to the latter was added.

Crooks rely on this feature in their approach to gain money using illegal advertising. They trick victims into allowing the pop-ups, and then just spread hundreds of ads of anyone they have a deal with. As you can suppose, no normal organisations will contract with fraudsters. All the Qr-captcha popups you can see lead to other fraudulent sites. At some point, the same victim may get into a trap of several pop-up spamming sites, and its browser will turn into a complete mess.

The ads these crooks show are paid under the pay-per-view model. It commonly provides a miserable payment for one viewer, but when you have hundreds of users and make it hundreds of times each day – that is a way bigger sum. Even though most of such banners are ineffective, it may still bring all the parties a lot of profit.

Are Qr-captcha pop-up ads dangerous?

Yes, they are. At the surface, they may look harmless – just a colourful pop-up that appears from time to time. However, the contents of this window differ drastically from what you used to see in pop-ups. Qr-captcha.com web page is controlled by fraudsters, who deliberately throw hundreds and thousands of irrelevant ads in pop-ups. They also never follow any common sense and can make sporadic push notifications into a hurricane of promotions. For weak systems, that may be enough to cause performance issues. But troubles are not over at this point.

As with any other thing that touches illegal advertising, Qr-captcha pop-ups don’t have legit deals to offer. Even when crooks make the banners looking similar to ones from well-known retailers, 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, Qr-captcha 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 Qr-captcha pop-ups?

Fortunately, Qr-captcha pop-up advertisements removal is pretty easy. They reside in the browser and cannot hide themselves among system files. However, as I stated before, some push notifications may introduce malicious programs to your computer. It is nearly impossible to describe all of the cases, and manual attempts to remove malware is a poor idea. For that reason, after removing the source of the pop-up ads it is recommended to use anti-malware software. That is especially recommended in the case when you have never clicked “Allow” to pop-up advertisements, and they still appeared. This situation may point at malicious software activity. GridinSoft Anti-Malware will be the best both system recovery and malware scanning purposes, thanks to its system recovery functionality and multi-component detection system.

Initially, you should reset your browser settings. You can do that in manual or automated way. The former, obviously, requires more time to complete and can be somewhat complicated if you have never done that. Automated supposes the use of anti-malware programs that can reset all browser settings at once.
