Question

Issue: How to fix RDN/TROJAN.WORM!055BCCAC9FEC pop-up?

Please advise asap! I receive an error message RDN/TROJAN.WORM!055BCCAC9FEC while browsing with Edge. I’ve tried Chrome, but it throws the same error window as well.

There was a telephone number given, but when I called it some guy speaking very poor English asked me to pay $150.00 to fix the problem. He stated that this error is fatal and may lead to identity theft and other crimes. However, that guy did not seem reliable… it claims that he‘s working for Microsoft and that he is located in NY, but that accent and lack of knowledge raise my suspicions.

Could you please tell me is there something I should worry about?

Solved Answer

RDN/TROJAN.WORM!055BCCAC9FEC is yet another Rogue Tech-Support-Scam,[1] which is an alteration of RDN/YahLover.worm!055BCCAC9FEC scam. Both of these rogue alerts are actively circulating around the Internet these days. As soon as you notice the pop-up, which contains one of the above-mentioned errors, report it to Microsoft[2] so that the company could perform a detailed investigation.

RDN/TROJAN.WORM!055BCCAC9FEC pop-up alert on Chrome, Edge or another web browser is pushed out by a potentially unwanted program (PUP) – unpopular ‘adware.’[3] 

Unfortunately, security experts haven’t yet tracked down what particular programs hackers misuse to spread RDN/TROJAN.WORM!055BCCAC9FEC adware, but, judging from people’s reports, the biggest chances to run into it is to download third-party programs (e.g. download managers, media players, mini-games, ad-blockers, etc.).

Therefore, be very cautious when installing apps from third-party download sources like cnet, softonic, and others. To prevent installation of software bundles,[4] opt for Advanced installation setup and carefully check if the software hasn’t been complemented with pre-checked attachments (web browser add-ons, toolbars, extensions). Make sure that you unmark all of them or, at best, reject the installation.Remove RDN/TROJAN.WORM!055BCCAC9FEC pop-up

If the adware that carries a malicious code of RDN/TROJAN.WORM!055BCCAC9FEC scam infiltrates the target system, it injects itself into the startup, modifies web browser’s settings and creates a scheduled task on a web browser, which further starts bringing the fake alert message to the user. The alert mimics an official Google Security Warning and contains such false claims:

  • The message is a Google Security Warning;
  • The PC is infected with RDN/TROJAN.WORM!055BCCAC9FEC;
  • The owner of the infected PC is at the risk of identity theft, loss of credit card details;
  • The only solution – to call for Microsoft-certified technicians (the number is provided).

Such information is fake, so ignore the pop-up and DO NOT call the pretend-to-be Microsoft technicians. Many people fall for believing that RDN/TROJAN.WORM!055BCCAC9FEC pop-up is genuine and called the given number. The outcome – they were asked to pay $150 for the “virus removal.”

Be sure that paying the money will not help to fix your computer because there is not such virus as RDN/TROJAN.WORM!055BCCAC9FEC at all. All you have to do is to remove the deceptive adware from the system and reset your web browser’s settings. The guidelines on how to do that are given down below:
