Browser notification spam in general
Dating-universe[.]top, dariolelab[.]com, realatinusa[.]com, and buynads[.]com are merely a few examples of rogue sites that we have examined recently. These webpages display browser notifications that promote deceptive/malicious material.
Note that while legitimate content may be encountered via these advertisements – it is unlikely to be endorsed by its actual developers or other official parties. It is most probable that this promotion is performed by scammers who abuse a product's affiliate programs in order to obtain illegitimate commissions.
How did centrumbook[.]com gain permission to deliver spam notifications?
Since no website can deliver browsing notifications (adverts) without user consent, you have likely visited centrumbook[.]com and permitted their delivery by clicking "Allow", "Allow Notifications", or an analogous option displayed on this webpage.
It is pertinent to mention that rogue sites commonly used deception (e.g., fake CAPTCHA tests, clickbait, adult-oriented content, etc.) to entice visitors into enabling notifications.
How to prevent deceptive sites from delivering spam notifications?
To avoid receiving unwanted browser notifications – do not enable questionable websites to deliver them (i.e., do not press "Allow", "Allow Notifications", etc.). Instead, deny notification delivery (i.e., click "Block", "Block Notifications", etc.) or ignore such requests altogether.
Should your browser continuously force-open suspect webpages, it could be due to the presence of advertising-supported software (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.
