Browser notification spam in general

We have investigated thousands of rogue websites; celebbuzzingfunny[.]top, deszubaton[.]com, and jaikaijoup[.]com are merely a couple of our latest finds.

These pages display browser notifications that promote deceptive and malicious content. Remember that any genuine products/services encountered via these advertisements are most likely endorsed by scammers who abuse their affiliate programs to obtain illegitimate commissions.

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

Websites cannot deliver browser notifications without user permission. Hence, you have likely entered the checkouroffer[.]com page at some point and consented to the advertisement delivery by clicking "Allow", "Allow Notifications", or a similar option.

Keep in mind that rogue sites often use deception (e.g., clickbait, fake CAPTCHA verification tests, adult-oriented content, etc.) to lure visitors into enabling notifications.

How to prevent deceptive sites from delivering spam notifications?

It is crucial to be selective when permitting sites to deliver browser notifications. Dubious webpages must not be allowed to display these ads; instead, such requests have to be ignored or denied (i.e., by selecting "Block", "Block Notifications", etc.).

In case of continuous unprompted redirects to questionable websites, check the browser and system for installed advertising-supported software (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.
