How to get rid of the advertisements delivered by deviceunder-shield.com

What kind of page is deviceunder-shield[.]com?

While inspecting untrustworthy sites, our researchers found the deviceunder-shield[.]com rogue webpage. It is designed to load scams, push browser notification spam, and redirect visitors to other (likely dubious/malicious) websites. Most users enter deviceunder-shield[.]com and sites akin to it via redirects caused by pages using rogue advertising networks.

Deviceunder-shield[.]com overview

It is worth noting that the behavior of rogue webpages (i.e., what they host/promote) may depend on the visitor's IP address/ geolocation.

When we entered deviceunder-shield[.]com, it ran the "Your Chrome is severely damaged by 13 Malware!" scam. This scheme consists of multiple pop-up windows falsely claiming that the visitor's device is infected. It must be emphasized that no website can detect threats/issues present in visitors' systems.

Deceptive content of this kind usually promotes adware, browser hijackers, fake anti-virus tools, and various PUAs. More information on the scam run on this page can be found in our "Your Chrome is severely damaged by 13 Malware!" article.

Some variants also displayed a pop-up attempting to trick users into enabling deviceunder-shield[.]com to display browser notifications. Rogue sites use them to deliver intrusive advertisement campaigns. These notifications/ads endorse unreliable/harmful websites and software, online scams, and even malware.

In summary, via webpages like deviceunder-shield[.]com - users can experience system infections, severe privacy issues, financial losses, and identity theft.

Browser notification spam in general

Saumeechoa[.]com, exclusivedealsfinder[.]com, expressedsupply[.]com, yourdesktopdefence[.]com, and notfreeads[.]com are merely some examples of the rogue sites we have analyzed.

The browser notifications delivered by these websites typically push scams and malicious material. Any legitimate products encountered through these advertisements are unlikely to be endorsed by their developers. Instead, this promotion is primarily undertaken by scammers abusing the products' affiliate programs to acquire illegitimate commissions.

How did deviceunder-shield[.]com gain permission to deliver spam notifications?

Sites are incapable of displaying browser notifications without user permission. Therefore, you have likely accessed deviceunder-shield[.]com at some point and allowed it to deliver these ads. Note that rogue websites commonly use deception (e.g., scare tactics, clickbait, fake CAPTCHA, etc.) to trick visitors into consenting to their notification delivery.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving unwanted browser notifications, we advise against permitting suspicious websites to deliver them. In other words, do not press "Allow", "Allow Notifications", or similar options present on such pages. We recommend ignoring or denying notification delivery (i.e., clicking "Block", "Block Notifications", etc.).

Should your browser continuously force-open unreliable/dubious webpages, it might be caused by 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.
