Browser notification spam in general

There are thousands of sites similar to bestsystemav[.]xyz online; youtubecenter.net, profitedsurvey.site, myhypeposts.com, and mydesktopdefence.com are just some examples.

The browser notifications originating from these webpages usually promote dubious and malicious content, but they are also commonly used in affiliate programs to endorse genuine products. The scammers (affiliates) advertise the former to receive illegitimate commissions.

How did bestsystemav[.]xyz gain permission to deliver spam notifications?

Websites deliver browser notifications with user consent. In other words, when visitors click the "Allow", "Allow Notifications", or similar buttons/options - they enable the site to display this graphical content. It is noteworthy that most rogue pages use deception (e.g., clickbait, fake CAPTCHA verification, etc.) to trick users into allowing their notifications.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving unsolicited browser notifications, avoid clicking "Allow", "Allow Notifications", or other consent options. Instead, notification requests must be ignored or denied (e.g., "Block", "Block Notifications", etc.).

Should a browser be force-opening suspect websites (e.g., bestsystemav[.]xyz), it is likely due to adware installed onto the system. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
