These websites display browser notifications that endorse deceptive and malicious content. Keep in mind that any genuine products or services encountered through these advertisements are most likely promoted by scammers abusing their affiliate programs to obtain illegitimate commissions.

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

Websites require user consent to deliver browser notifications. Hence, if you are seeing these adverts from coisigne[.]com – it is evident that when this page was visited, permission for their delivery was granted by clicking "Allow", "Allow Notifications", or a similar option.

How to prevent deceptive sites from delivering spam notifications?

It is important to always be selective when allowing sites to display browser notifications. Suspect webpages must not be permitted to do so; instead, these requests have to be ignored or denied (i.e., by pressing "Block", "Block Notifications", etc.).

In case of continuous unprompted redirects to dubious pages, check the browser and system 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.
