This article explains the issues that occur in case of infection with .tro files virus and provides a complete guide on how to remove malicious files and how to potentially recover files encrypted by this ransomware.
An infection with the so-called .tro files virus leads to the corruption of important files. For their corruption, it utilizes sophisticated cipher algorithm. With the help of this algorithm, it transforms parts of the original code of target files and leaves them out of order. Soon after this ransomware encodes target files, it opens a ransom message to extort ransom payment for their recovery.

.tro Files Virus – Distribution
Like many other crypto viruses, .tro is likely to be spread as a part of malicious email messages. This spread method is called malspam and in this paragraph, you will learn more about its typical components. Typical of these emails are:
An URL address presented in the form of an in-text link, button, image, banner or other form. Once loaded in the browser the web page associated with this link usually triggers an automatic download process of the malicious ransomware payload. After downloading the payload the same page usually activates specific scripts that execute it directly on your PC.
An attachment that contains the malware in it. Usually, according to the text message this file should be reviewed as soon as possible due to the importance of its information. The moment you open it on your device is the moment when you trigger the infection process with .djvu files virus. This file may be a familiar type of file such as .rar, .zip, .7z, .docx When infected such a file could be set to evade active security measures and complete the attack without leaving you any chance of detecting the malicious activities it performs on the background.
Since the security of your device and your data is of paramount importance we recommend you to use the help of free online scanners like VirusTotal and ZipeZip every next time you receive a questionable email that contains any of the mentioned components. With the help of these scanners, you will easily identify whether the components are malicious or not.
Other possible infection vectors that may be preferred by the creators of this .djvu crypto virus may be malicious advertising, browser redirects,

.pdff, hackers decided to shift to this brand new variant that is associated with the .tro extension.
Now let’s review what happens when this threat manages to run its payload file on a target system. Initially, .tro files virus establishes a bunch of malicious files on the system. For their location, the ransomware may use the following folders:
%Roaming%
%Windows%
%AppData%
%Local%
%Temp%
With the help of all established malicious files, .tro ransomware interferes with the settings of essential system components. One of the affected components is likely to be the Registry Editor. Since it is a hierarchical database that keeps low-level settings for the Windows operating system, ransomware is often set to access and plague it. This could be explained by the fact that some registry keys’ functionalities enable the ransomware to load on each system start.
Soon after .tro implements all infection stages it drops a text file called _openme.txt and loads it on the screen. With the help of this file, it informs you about its presence and attempts to blackmail you into paying ransom for files decryption. Below you could see the whole message:
———————————————- ALL YOUR FILES ARE ENCRYPTED ———————————————–

4. Try to Restore files encrypted by .tro Files Virus
Try to Restore Files Encrypted by .tro Files Virus
Ransomware infections and .tro Files 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:
