TYCX Virus [.tycx Files] Ransomware – Remove + Decrypt

What Is Tycx Virus?

The TYCX virus is a ransomware that belongs to the STOP/DJVU family and affects Windows OSs. It employs a complex encryption process to lock the files, appending the .tycx extension to them. Subsequently, a ransom note is displayed, requesting the victims to pay a certain sum of money to get the decryption key and recover access to the blocked files. If the payment isn’t made within the allotted time, the files may be irreversibly erased.

What Is Ransomware?

Ransomware is a type of malicious software designed to deny access to a computer system or data until a ransom is paid. Usually, it is disseminated through phishing emails, malicious links, or by exploiting existing software vulnerabilities. This type of malware is capable of encrypting files and/or locking users out of their computers, making it almost impossible to access data without paying the ransom.

Tycx Virus – How Did I Get Infected?

This virus is usually circulated through emails and webpages that contain hazardous material, as well as through downloading dangerous software. Additionally, security vulnerabilities in the operating system or other software may be taken advantage of to contract the virus. The major ways of dispersal for this ransomware:

  • If it is sent to you as an e-mail attachment or a URL.
  • By being downloaded from a shady site.

Once the ransomware has infiltrated your system, it will start to encrypt your documents. It will then display a prompt requesting a payment for the decryption key which will give you access to the encrypted files. Usually, the notification will alert that the encrypted files will be deleted for good if the ransom is not paid before a certain deadline.

The virus ay leave its payload files in the following directories:

  • %Local%
  • %Temp%
  • %Windows%
  • %SystemDrive%
  • %LocalLow%
  • %AppData%
  • %System%
  • %system32%

The Tycx virus diffuses its _readme.txt ransom note, the text of which reads:

Tycx virus may generate numerous value entries, some of which could exist in the Windows Run and RunOnce Registries .

What Are .tycx Files

Files with the .tycx extension have been infiltrated by ransomware, making them inaccessible until the encryption is removed. To retrieve the files, either the ransom should be paid or a trustworthy data recovery tool employed. This virus targets certain file types and applies the AES encryption algorithm to encrypt them.

  • Videos (.mp4, .avi, etc.).
  • Audio (.mp3, .wav, etc.).
  • Picture file kinds (.jpg, .png, .etc).
  • Archive file formats (.zip, .rar, etc).
  • Documents of different types (.docx, .pptx, etc.).
  • Others.

After encryption, the files begin to appear, like the following:

How to Open .tycx Files

Upon the detection of .tycx virus ransomware on your system, the most critical thing to do is to delete the malicious virus and recover the files from a backup, as it is impossible to open the encrypted files without paying the ransom demanded by the cybercriminals. If it is DJVU ransomware that has encrypted your files, the same action should be taken as a priority.

What To Do If My Files Are .tycx?

The only guaranteed way to retrieve files encrypted by Tycx virus ransomware is to restore them from a backup or by reversing the cipher. If no backup is accessible, data restoration software can be employed in an effort to get back the files, as outlined in the guide below. Yet, there is no promise that these procedures will be effective.
