Trojan ransomware removal instructions

What is Trojan?

Trojan is a ransomware-type virus discovered by MalwareHunterTeam. Immediately after infiltration, Trojan encrypts most stored data and appends filenames with the ".tron" extension (e.g., "sample.jpg" is renamed to "sample.jpg.tron"). Once files are encrypted, using them becomes impossible. Immediately after data encryption data, Trojan opens a pop-up window with a ransom-demand message.

Trojan detects if a Russian locale is installed. If so, the virus automatically terminates itself and does not encrypt data. Therefore, it is safe to assume that cyber criminals are Russian and attempt to protect their fellow citizens. The ransom-demand message informs victims of the encryption and instructs them what to do next. To decrypt data, victims must pay a ransom. It is currently unknown whether Trojan uses symmetric or asymmetric cryptography, since this information is not provided, however, decryption requires a unique key generated individually for each victim. These keys are stored on a hidden server controlled by Trojan's developers, and thus users are encouraged to pay .05 Bitcoin (currently equivalent to approximately $400) for their release. Furthermore, cyber criminals can never be trusted. Research shows that these people often ignore victims, once payments are submitted. Therefore, paying typically gives no positive results and users are scammed. You are strongly advised to ignore all requests to submit payments. There are currently no tools capable of restoring files encrypted by Trojan and you can only attempt to restore everything from a backup.

Trojan is virtually identical to Ladon, CYBERRESEARCHER, Iron, RSA2048Pro, and dozens of other ransomware-type viruses. Research shows that although these viruses are developed by different cyber criminals, their behavior is virtually identical - all encrypt data and make ransom demands. The only major differences are size of ransom and type of encryption algorithm used. Unfortunately, most of these viruses employ algorithms that generate unique decryption keys. Therefore, in most cases file decryption manually is impossible. The only possible scenarios are ransomware not being fully developed or having certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar). These viruses present a strong case for maintaining regular data backups, however, keep backup files on a remote server (e.g., Cloud) or unplugged storage device, otherwise the backups are encrypted together with regular data.

How did ransomware infect my computer?

To promote ransomware, developers employ spam emails (infectious attachments), peer-to-peer (P2P) networks, third party software download sources, fake software updaters, and trojans. Malicious attachments typically come in the format of JavaScript files or MS Office documents. Once opened, these files execute code that stealthily downloads and installs malware. P2P networks (torrents, eMule, etc.) and other unofficial software download sources (free file hosting/freeware download websites, etc.) present malware as legitimate software. Therefore, many users are tricked into downloading and installing malware. Fake software updaters infect the system by exploiting outdated software bugs/flaws or merely downloading and installing malware rather than updates. Trojans are the simplest of all - they merely open "backdoors" for other high-risk malware to infiltrate the system. In summary, the main reasons for computer infections are lack of knowledge and careless behavior.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, to prevent ransomware infections, be very cautious when browsing the Internet. Think twice before opening email attachments. If the file seems irrelevant or has been sent from a suspicious email address, do not download/open it and delete the email immediately. Furthermore, we strongly advise you to download your applications from official sources only, using direct download links. Third party downloaders/installers should never be used, since they are likely to include rogue applications. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. Since criminals proliferate malware using fake updaters, apps should be updated using implemented functions or tools provided by the official developer only.

Step 2

Log in to the account infected with the Trojan virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

system restore using command prompt type cd restore

3. Next, type this line: rstrui.exe and press ENTER.

system restore using command prompt rstrui.exe

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Trojan ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Trojan ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Trojan are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Trojan, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Trojan ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
