How to remove YTBN ransomware (Virus Removal Guide)
Published on March 31, 2021 by Stelian Pilici | Filed Under: Ransomware
If you cannot open your images, documents, or files and they have a .ytbn extension, then your computer is infected with ransomware.
The YTBN ransomware is a malicious program that encrypts the personal documents found on the victim’s computer with the “.ytbn” extension, then displays a message which offers to decrypt the data if payment in Bitcoin is made. The instructions are placed on the victim’s desktop in the “_readme.txt” file.
What is the YTBN ransomware?
YTBN is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.ytbn” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of Bitcoin cryptocurrency, in exchange for access to data.
When you are first infected with the YTBN ransomware it will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.ytbn”, so that you are no longer able to be open them.
Once the YTBN ransomware has encrypted the files on your computer, it will display the “_readme.txt” file that contains the ransom note and instructions on how to contact the authors of this ransomware. The victims of this ransomware will be asked to contact the cybercriminals via the [email protected] and [email protected] email addresses.
This is the ransom note that the YTBN ransomware will show to its victims:

How did the YTBN ransomware get on my computer?
The YTBN ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed programs.
Here’s how the YTBN ransomware might get on your computer:
- Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the YTBN ransomware.
- The YTBN ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.
Remove the YTBN ransomware and recover the files
It’s important to understand that by starting the removal process you risk losing your files, as we cannot guarantee that you will be able to recover them. Your files may be permanently compromised when trying to remove this infection or trying to recover the encrypted documents. We cannot be held responsible for losing your files or documents during this removal process.

We’re using Safe mode because it starts Windows in a basic state, using a limited set of files and drivers.Windows 10 or Windows 8Windows 7Before you enter Safe Mode, you need to enter the Windows Recovery Environment (winRE). To do this, follow the below steps:

Option 1: Use Emsisoft Decryptor for STOP Djvu to restore the files
