What kind of page is device-undershield[.]com?

While inspecting unreliable webpages, our researchers found the device-undershield[.]com site. It operates by running scams, pushing browser notification spam, and redirecting visitors to different (likely dubious/malicious) websites. Users typically enter pages like device-undershield[.]com through sites that use rogue advertising networks.

Device-undershield[.]com overview

It is noteworthy that the behavior of rogue websites (i.e., what they host and promote) might vary depending on visitors' IP addresses/ geolocations.

Once we accessed device-undershield[.]com, we discovered that it endorses various scams (e.g., "Chrome is infected with Trojan:SLocker"). The schemes we saw on this webpage warned visitors that their browsers/systems were infected or at risk of infection.

It must be emphasized that no site can detect threats or issues present on a visitor's device; hence, any that make such claims are scams. In most cases, they push untrustworthy and malicious software (e.g., adware, browser hijackers, trojans, etc.).

Additionally, device-undershield[.]com requests users to allow it to display browser notifications. Rogue pages employ them to run intrusive advertisement campaigns. The notifications/ads promote online scams, unreliable/harmful webpages and software, and even malware.

Therefore, through websites like device-undershield[.]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; now-scan[.]com, pcprotect[.]name, cleaningupdate[.]xyz, and remindexpert[.]xyz are just some examples.

These pages deliver browser notifications that endorse deceptive and malicious material. Note that any legitimate products encountered via these advertisements are unlikely to be promoted by their actual developers. Instead, this promotion is undertaken by scammers abusing the products' affiliate programs to obtain illegitimate commissions.

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

Sites need user permission to display browser notifications. Therefore, you have likely accessed device-undershield[.]com and some point and given your consent by clicking "Allow", "Allow Notifications", or an analogous option.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving unwanted browser notifications from suspicious websites, we advise against clicking "Allow", "Allow Notifications", or similar options that would give consent to the delivery of these ads. We recommend ignoring or denying notification delivery requests (i.e., pressing "Block", "Block Notifications", etc.).

Should your browser continuously force-open questionable webpages without prompt, it could be caused by the presence of 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.
