Removing notifications/adverts delivered by the datadefenceservice.com site

What kind of page is datadefenceservice[.]com?

Datadefenceservice[.]com is a rogue website our research team found while inspecting untrustworthy pages. It operates by loading deceptive material, promoting spam browser notifications, and redirecting visitors to other (likely unreliable/hazardous) sites.

Most users enter such webpages via redirects caused by sites using rogue advertising networks. However, these pages can also be accessed through mistyped URLs or redirects from intrusive ads, spam notifications, or installed adware.

Datadefenceservice[.]com overview

The behavior of rogue pages can depend on the visitor's IP address/ geolocation. Hence, what users encounter on or via websites like datadefenceservice[.]com can vary. During our inspections, we discovered that this site runs two similar scams.

Both schemes consist of fake anti-virus interfaces, system scans, and threat reports - the latter falsely claiming that the visitor's device is infected.

Typically, scams of this kind are used to endorse fake anti-viruses, browser hijackers, adware, and various PUAs. More information on these scams can be found in their respective articles "Norton Security - Your PC is infected with 5 viruses!" and "McAfee - Your PC is infected with 5 viruses!".

Furthermore, datadefenceservice[.]com requests visitors to enable its browser notifications. These notifications/advertisements usually push untrustworthy/harmful sites and software, online scams, and even malware.

To summarize, through websites like datadefenceservice[.]com, users can experience system infections, severe privacy issues, financial losses, and even identity theft.

Browser notification spam in general

News-cihumo[.]cc, myhypestories[.]com, and emicalcove[.]xyz are just a couple of examples of the rogue pages we have analyzed.

The browser notifications displayed by such websites primarily endorse dubious and malicious content. It is pertinent to mention that any legitimate products encountered through these ads are unlikely to be advertised in this fashion by their actual developers. Instead, this promotion is usually done by scammers who abuse affiliate programs to acquire illegitimate commissions.

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

Sites can only deliver notifications with user permissions. Therefore, you have likely permitted datadefenceservice[.]com to run these advertisement campaigns (i.e., clicked "Allow", "Allow Notifications", or a similar option). Note that rogue webpages often use deception (e.g., clickbait, fake CAPTCHA verification, etc.) to lure visitors into enabling their browser notifications.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving undesirable browser notifications, we advise against consenting to their delivery from questionable sites (i.e., do not press "Allow", "Allow Notifications", or analogous options). We recommend ignoring or denying notification delivery requests (i.e., select "Block", "Block Notifications", or similar).

Should your browser continuously force-open suspect websites, it might be due to 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.

How to avoid browser notification spam?

Internet users should be very skeptical when being asked to allow notifications. While this is a useful feature that allows you to receive timely news from websites you like, deceptive marketers frequently abuse it.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
