Browser notification spam in general

We have investigated numerous rogue pages; mac-uptodate[.]com, wsdefender[.]xyz, avscan[.]buzz, and groopheetex[.]com are merely a couple of our newest articles. Websites of this kind deliver browser notifications promoting deceptive and malicious content.

While legitimate products or services may be encountered via these adverts – they are unlikely to be endorsed by any official parties. It is most probable that this promotion is undertaken by scammers who abuse the promoted content's affiliate programs to obtain illegitimate commissions.

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

Websites require user consent to deliver browser notifications. Therefore, you have likely accessed prizestash[.]com at some point and permitted the advert delivery by clicking "Allow", "Allow Notifications", or an analogous option displayed on this page.

It is noteworthy that rogue sites commonly use various lures (e.g., clickbait, fake CAPTCHA verification tests, adult-oriented content, etc.) to trick visitors into enabling notifications.

How to prevent deceptive sites from delivering spam notifications?

It is essential to be selective when permitting browser notification delivery. Dubious pages must not be enabled to display these ads; instead, ignore or deny their requests (i.e., press "Block", "Block Notifications", etc.).

In case of continuous unprompted redirects to suspect websites, inspect the device for installed adware. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
