Tecolah.com. RDM/Trojan.Worm!055BCCAC9FEC pop-up alert blocks Microsoft Edge from time to time and urges me to call the number provided unless I don’t care to get my passwords, logins, and other personal data damaged.

If your web browser’s screen gets stuck with the RDN/YahLover.worm!055BCCAC9FEC pop-up generated by web-alrt-phsng-atck.xyz URL, it means that your PC has been infected with a potentially unwanted program (PUP), known as aware. The message is classified as Rogue Tech-Support-Scam due to the fact that it contains fake information to intimidate people and prompt them to contact a pretend-to-be Microsoft-certified technician.

Usually, the message is generated by web-alrt-phsng-atck.xyz, but the URL may vary. It is stated that information related to the passwords, credit card details, and web browsing history will be damaged and stolen. However, that’s just a trick that scammers use to make people dial a high-priority telephone number provided on the pop-up and get into the trap of scammers who may seek to establish a connection with your PC remotely and, furthermore, steal personal information like credit card details, passwords, full name, etc. Therefore, do not fall for believing in RDN/YahLover.worm!055BCCAC9FEC fake pop-up under any circumstances.

As we have already pointed out, RDN/YahLover.worm!055BCCAC9FEC scam is triggered by an adware. Typically, this type of cyber threats spread via bundled installers. In other words, if you download a third-party software via untrustworthy source and select Quick installation setup, you may inadvertently agree to install a whole pack of programs, including RDN/YahLover.worm!055BCCAC9FEC adware. It injects a malicious web browser extension into Microsoft Edge, which then initiates fake tech-support-scam alerts. According to users’ reports, it turns out that the alert freezes the web browser and blocks Task Manager, which is why the PC’s screen gets stuck. Even them, DO NOT call the given number. Instead of that, perform the steps to fix RDN/YahLover.worm!055BCCAC9FEC error given down below:
