Browser notification spam in general

We have examined numerous rogue pages; techadsmecity[.]com, thecanetdesign[.]com, ntmadz[.]com, and news-rujopo[.]com are just some of our newest articles. The purpose of these sites is to deceive visitors into enabling browser notifications. Typically, rogue webpages use various lures, such as fake CAPTCHA tests, clickbait, adult-oriented content, etc.

Spam notifications promote online scams and malicious content. While legitimate products or services can be encountered via these ads – they are unlikely to be endorsed in this manner by any official parties. It is most probable that this endorsement is undertaken by scammers who abuse the content's affiliate programs to obtain illegitimate commissions.

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

Websites need user consent to deliver browser notifications. Hence, if you are receiving these ads from tetradsgroup[.]com – it means that you have likely accessed this page and clicked "Allow", "Allow Notifications", or an analogous option presented on this page.

How to prevent deceptive sites from delivering spam notifications?

If you happen upon a suspect page – do not permit it to display browser notifications (i.e., do not click "Allow", "Allow Notifications", etc.). Instead, ignore or deny notification requests (i.e., press "Block", "Block Notifications", etc.).

Should your browser continuously force-open suspicious sites without prompt, it could be due to adware installed 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.
