Browser notification spam in general

We have investigated countless rogue pages; ratenowpage[.]site, pohsoneche[.]info, and snadsnews[.]com are just a few of our newest articles. The purpose of these websites is to entice users into consenting to their browser notification delivery, yet how they achieve this goal can differ greatly.

Spam notifications endorse deceptive and malicious content. While legitimate products or services may be encountered via these adverts – they are unlikely to be promoted by their developers or other official parties. This promotion is most likely undertaken by scammers motivated to obtain illegitimate commissions by abusing the endorsed content's affiliate programs.

How did sundermima[.]com gain permission to deliver spam notifications?

Websites cannot deliver browser notifications without user consent. Therefore, if you are seeing these advertisements from sundermima[.]com – it is evident that when this page was visited, permission for their delivery was given by selecting "Allow", "Allow Notifications", or a similar option.

How to prevent deceptive sites from delivering spam notifications?

It is important to always be selective when enabling websites to deliver browser notifications. Questionable pages must not be permitted to display these ads; instead, such requests have to be ignored or denied (i.e., by pressing "Block", "Block Notifications", etc.).

It is worth mentioning that having adware installed on the browser/system can result in dubious sites being force-opened at random. Should you keep experiencing redirects of this kind, inspect the device and immediately remove all dubious applications and browser extensions/plug-ins.

If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
