Also Known As: "RDN/Trojan.worm!055BCCAC9FEC Infection" virus
Damage level: Medium

What is RDN_Trojan.worm!055BCCAC9FEC Infection?

Similar to RDN/Trojan/Hacking, RDN/YahLover.worm Infection, and many others, "RDN_Trojan.worm!055BCCAC9FEC" Infection is a fake error message displayed by various deceptive websites. Research shows that most visitors arrive at these sites inadvertently - they are redirected by potentially unwanted programs (PUPs) or intrusive ads delivered by other rogue sites.

In most cases, potentially unwanted programs infiltrate systems without permission and, as well as causing redirects, deliver intrusive advertisements, gather various information, and (sometimes) misuse system resources to run unwanted background processes.

This error states that the system is infected with a type of trojan virus that poses a direct threat to users' personal data (logins/passwords, banking information, etc.) Users are encouraged to eliminate the malware immediately, however, they must first contact Microsoft 'tech support' via a telephone number ("+61-1800-431-247") provided.

They are then supposedly guided through the malware removal process. Be aware, however, that this is a scam - "RDN_Trojan.worm!055BCCAC9FEC Infection" error is fake and has nothing to do with Microsoft. Cyber criminals generate revenue by tricking gullible users into calling and paying for services that are not required - your computer is probably safe.

For these reasons, ignore the "RDN_Trojan.worm!055BCCAC9FEC Infection" pop-up and never attempt to call the aforementioned telephone number. This error can be removed simply by closing the web browser, however, note that some sites employ scripts designed to prevent users from closing browsing tabs/windows.

In these cases, terminate the browser via Task Manager or simply reboot the system. After re-running the web browser, do not restore the previous session, otherwise you will return to the malicious site/s.

Potentially unwanted programs often deliver various intrusive advertisements (such as coupons, banners, pop-ups, and similar). To achieve this, they employ various tools that enable placement of third party graphical content on any site. Therefore, intrusive ads often conceal underlying content, thereby significantly diminishing the browsing experience.

Furthermore, these ads might lead to malicious websites and execute scripts that stealthily download and install malware. Therefore, even a single accidental click can result in high-risk computer infections. In addition, PUPs gather information such as IP addresses, URLs visited, pages viewed, search queries, keystrokes, and similar.

The data often includes personal details that developers share with third parties (potentially, cyber criminals). These people misuse personal details to generate revenue. Therefore, having information-tracking apps installed on your computer can lead to serious privacy issues or even identity theft.

Furthermore, potentially unwanted programs often misuse system resources to mine cryptocurrencies or run other unwanted processes without consent. This reduces overall system performance. For these reasons, we strongly advise you to uninstall all potentially unwanted programs immediately.

As mentioned above, "RDN_Trojan.worm!055BCCAC9FEC Infection" shares many similarities with dozens of other fake errors. All claim that the system is damaged (e.g., infected, missing files, etc.), however, these errors are designed only to extort money from unsuspecting users. Potentially unwanted programs are also known to have many similarities.

By offering various "useful features", they attempt to give the impression of legitimacy. Following infiltration, however, PUPs provide no real value for regular users. These programs are designed only to generate revenue for the developers. Rather than enabling any of the functions promised, PUPs pose a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Some PUPs have official download/promotion sites, however, in most cases, these applications infiltrate systems without permission, since developers promote them using intrusive advertisements and a deceptive marketing method called "bundling". Developers know that users often rush download/installation processes and skip steps.

Therefore, they hide "bundled" apps within "Custom/Advanced" settings or other sections of the download/installation processes. Skipping these steps (and clicking on various advertisements) exposes their systems to risk of various infections.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Intrusive advertisements typically seem legitimate, however, they redirect to gambling, adult dating, pornography, and other dubious websites.

If you experience these redirects, immediately eliminate all dubious applications and browser plug-ins. Furthermore, carefully analyze each window download/installation dialogs and opt-out of all additionally-included programs.

You are also advised to avoid using third party downloaders/installers, since they are often monetized by promoting ("bundling") PUPs. Software should be downloaded from official sources only, using direct download links.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:

  • Spelling mistakes and non-professional images - Closely inspect the information displayed in a pop-up. Spelling mistakes and unprofessional images could be a sign of a scam.
  • Sense of urgency - Countdown timer with a couple of minutes on it, asking you to enter your personal information or subscribe to some online service.
  • Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
  • Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
  • Exclusivity - Pop-up windows stating that only you are given secret access to a financial scheme that can quickly make you rich.

How do pop-up scams work?

Cybercriminals and deceptive marketers usually use various advertising networks, search engine poisoning techniques, and shady websites to generate traffic to their pop-ups. Users land on their online lures after clicking on fake download buttons, using a torrent website, or simply clicking on an Internet search engine result.

Based on users' location and device information, they are presented with a scam pop-up. Lures presented in such pop-ups range from get-rich-quick schemes to fake virus scans.
