Defenderfordevice[.]com overview

The behavior of rogue websites (i.e., what they load/endorse) might depend on the visitor's IP address (geolocation). When we inspected defenderfordevice[.]com, we discovered two variants - one promoted a deceptive article praising an Android application, and the other was the "Your Chrome Is Severely Damaged By 13 Malware!" scam.

The latter makes false claims that the visitor's Chrome browser has been damaged by malware. It is noteworthy no website can detect threats/issues on visitors' devices. Both the bogus article and the scam - promote software that is likely harmful and could potentially be malicious.

Both versions of defenderfordevice[.]com attempt to deceive visitors into enabling browser notification delivery; they display a pop-up stating - "Missing permission detected/ Click on the bell icon shown in the top right/left of the address bar then click allow". If enabled, defenderfordevice[.]com will deliver notifications/ads promoting online scams, unreliable/harmful sites and software, and even malware.

In summary, via websites like defenderfordevice[.]com - users can experience system infections, serious privacy issues, financial losses, and identity theft.

Browser notification spam in general

We have analyzed thousands of rogue webpages; adslivetraining[.]comourhotposts[.]comchampse[.]click, and desktopdefence[.]online are merely some examples.

These browser notifications endorse deceptive and malicious content. It is pertinent to mention that any genuine products encountered via these advertisements are most likely promoted by scammers who abuse their affiliate programs to obtain illegitimate commissions.

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

Websites cannot deliver browser notifications without user consent. Therefore, you have likely accessed defenderfordevice[.]com and pressed "Allow", "Allow Notifications", or a similar option presented on this webpage.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving unwanted browser notifications, do not allow suspicious sites to deliver them (i.e., do not click "Allow", "Allow Notifications", etc.). We advise ignoring or denying notification requests (i.e., clicking "Block", "Block Notifications", etc.).

Should your browser continuously force-open questionable sites unprompted, it could be caused by the presence of adware on the device. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
