Removal instructions for notifications/ads delivered by b-cdn.net site

What kind of page is b-cdn[.]net?

Our researchers periodically inspect suspicious websites, and b-cdn[.]net is a new find from one of these inspections. B-cdn[.]net is a rogue page that loads dubious content (e.g., "Your McAfee Subscription Has Expired" scam), pushes its browser notifications, and redirects visitors to other untrustworthy/dangerous sites.

Most visitors to webpages like b-cdn[.]net access them via websites using rogue advertising networks. However, these pages can also be entered through mistyped URLs or redirects caused by deceptive browser notifications/ intrusive ads, or installed adware.

B-cdn[.]net overview

When we entered b-cdn[.]net, it presented us with a variant of the "Your McAfee Subscription Has Expired" scam and requested its browser notifications to be allowed. It is noteworthy that what such sites load/promote may be based on the visitor's IP address/geolocation; hence, what is encountered on or through a page can vary.

The scam version b-cdn[.]net displayed stated that the McAfee anti-virus subscription has expired and that the device is exposed to viruses/malware. When we clicked the "Renew Subscription" button, it redirected to an invalid webpage. We must emphasize that this scheme is in no way associated with McAfee Corp.

Usually, scams of this type are used to endorse fake anti-viruses, adware, browser hijackers, and various PUAs (Potentially Unwanted Applications). In seldom cases, we have observed deceptive websites proliferating malware. More information on "Your McAfee Subscription Has Expired" can be found in our article on this scam.

Additionally, b-cdn[.]net can run intrusive advertisement campaigns if it is allowed to deliver browser notifications. The notifications/adverts promote online scams, untrustworthy/harmful software, and even malware.

Browser notification spam in general

We have analyzed thousands of rogue websites; securestuff[.]xyz, webprotrctionprogramm[.]com, and 3v4lu4t3-4pp0intm3nt[.]xyz are just a few examples of those similar to b-cdn[.]net.

Most of the browser notifications displayed by such pages endorse questionable and malicious material. In seldom cases, they can promote legitimate products. However, it is exceedingly rare for genuine developers to use this marketing technique; the misleading promotion is usually done by scammers abusing affiliate programs to obtain illegitimate commissions.

How did b-cdn[.]net gain permission to deliver spam notifications?

Websites require user permission to deliver browser notifications; hence, you've likely visited b-cdn[.]net and allowed it to do so. Note that many rogue webpages use fake CAPTCHA, clickbait, or other deceptive content to trick visitors into enabling the notifications.

How to prevent deceptive sites from delivering spam notifications?

If you access a suspicious website, do not click "Allow", "Allow Notifications", or similar options that would enable it to display browser notifications. Instead, we strongly advise to ignore notification requests or deny them (i.e., "Block", "Block Notifications", etc.).

Dubious sites can also be force-opened by adware-affected browsers. It is pertinent to mention that this software can infiltrate systems without explicit user consent; therefore, it is possible to be unaware of its presence.

If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
