Browser notification spam in general

Dev-defense[.]com is a webpage practically identical to device-defense[.]com, and bringmesedline[.]com, etingplansfo[.]buzz, datingmint[.]top – are a couple examples of rogue pages that we have inspected recently. Websites of this kind display browser notifications that promote deceptive/malicious content.

Keep in mind that while legitimate products/services may be encountered through these adverts – they are highly unlikely to be endorsed by their actual developers. It is most probable that this endorsement is performed by scammers who abuse the content's affiliate programs in order to acquire illegitimate commissions.

How did device-defense[.]com gain permission to deliver spam notifications?

No website can deliver browser notifications (ads) without user permission. Therefore, you have likely accessed device-defense[.]com at some point and clicked "Allow", "Allow Notifications", or an analogous option displayed on this page – thus enabling the notification delivery.

How to prevent deceptive sites from delivering spam notifications?

Should you access a suspicious site – do not enable it to display browser notifications (i.e., do not press "Allow", "Allow Notifications", etc.). We recommend denying notification delivery (i.e., clicking "Block", "Block Notifications", etc.) or ignoring these requests in their entirety.

In case of continuous unprompted redirects to questionable webpages, check 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.
