Browser notification spam in general

We have analyzed thousands of rogue webpages; slinponga[.]xyz, lepigthree[.]xyz, powerpcfact[.]com – are merely a couple of examples.

The browser notifications delivered by such sites primarily endorse deceptive and malicious content. While legitimate products/services can be encountered through these ads – they are unlikely to be promoted by their actual developers. Typically, this endorsement is undertaken by scammers who abuse the content's affiliate programs in order to obtain illegitimate commissions.

How did greatcaptchanow[.]top gain permission to deliver spam notifications?

Websites need user permission to deliver browser notifications. Hence, if you are receiving these adverts from greatcaptchanow[.]top – it means that you've likely visited this page at some point and enabled their delivery by pressing "Allow", "Allow Notifications", or a similar option.

How to prevent deceptive sites from delivering spam notifications?

If you access a dubious webpage – do not enable it to display browser notifications (i.e., do not click "Allow", "Allow Notifications", etc.). We advise denying notification delivery (i.e., pressing "Block", "Block Notifications", etc.) or ignoring such requests altogether.

Should your browser continuously force-open suspicious websites without prompt – it could be caused by the presence of adware on the device. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
