In this article, you will find out how to remove .tornado file virus and restore data with the help of an available decryption tool.
The .tornado file virus is a severe threat that demands a ransom once it encodes sensitive data stored on a compromised host. Corrupted files can be recognized by the extension .tornado appended at the end of their names. In a file named key.txt you can find a ransom message that primarily aims to trick you into paying the ransom to hackers. The amount needs to be transferred to a Bitcoin address.

Detection Tool
See If Your System Has Been Affected by .tornado virus
Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
.tornado File Virus – Distribution
How the .tornado file virus may invade your system is via email spam messages, links to compromised web pages, freeware installers, fake software update notifications and other shady techniques of distribution.
Hackers mostly prefer the spam emails as senders’ names and subject lines are easily spoofed. The emails that deliver ransomware infections usually pose as reliable websites, services, or institutions. Common traits of emails carriers of malware are:
Spoofed email address and sender
Text messages that attempt to provoke sense of urgency
File attachment you need to download and see as soon as possible
In-text link you should follow in order to obtain important information
By opening a compromised file attachment, you automatically grant access to .tornado ransomware to your system. The same happens in case that you decide to click on the presented link and visit the web page.
.tornado File Virus – Infection Flow
Once .tornado file virus is running on your system it initiates a sequence of malicious actions. In the beginning, it may connect its command and control server in order to arm itself with all the needed files taht will help it to fulfill the attack. There are several essential Windows system folders where the malicious files may be dropped:
%AppData%
%Temp%
%Roaming%
%Common%
%System32%
Afterard, the crypto virus drops a ransom message and displays it on the screen. The ransom note file is called key.txt and could be located on the desktop. It primarily aims to urge you contact hackers at [email protected] or [email protected] and transfer an unspecified ransom to their Bitcoin address.
Below you can read the whole ransom message:
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail: [email protected] have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment, we will send you the decryption tool that will decrypt all your files.In case of no answer in 48 hours write us to these e-mails: [email protected] [redacted 512 hex]
If you don’t want to lose your money and get tricked again, it is better to try to overcome the problem with the help of reliable and secure solutions.
The threat has been proved to be a new iteration of the InsaneCrypt ransomware. Happily, the security researcher Michael Gillespie released an effective decryptor for the .tornado files. We have included it in the instructions below so you can utilize it after the removal process.
.tornado File Virus – Data Encryption
Being a data locker ransomware .tornado primarily aims to scan the system for predefined types of files in order to encrypt them. Security researchers who have been analyzing the threat’s samples stated that .tornado is supposed to utilize the RSA cipher to encode target data.
After encryption, all corrupted files can be recognized by the two specific file extensions appended at the end of their names. The string follows the pattern:
→.[email].Tornado
Files that store important information like documents, text files, databases, projects, audio records, images and photos may be encrypted in case .tornado file virus infection.
Unfortunately, the ransomware leaves all encrypted files completely out of order. Your access to all .tornado files is restricted until you pay the ransom or utilize alternative data recovery approach. Some of these approaches are listed in our guide below.
Тo reduce the data recovery options with one, the crypto virus currently known as Tornado, opens the Command Prompt panel to write the following command there:
→vssadmin.exe Delete Shadows /All /Quiet
Thereby, the ransomware deletes all Shadow Volume copies stored by the Windows system.

4. Try to Restore files encrypted by .tornado virus
Try to Restore Files Encrypted by .tornado virus
Ransomware infections and .tornado virus aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
