ThunderX Ransomware


ThunderX is a representative of one of the worst categories of malware – the so-called file-locking ransomware viruses. The goal of ThunderX and other malware programs similar to it is to block the access to your data and then demand a ransom for its release.

The ThunderX Ransomware ransom note

This type of malware has now been around for some time and hackers have had the opportunity to perfect it and come up with more sophisticated methods of distributing it. Nowadays, ransomware threats like this one are oftentimes delivered in secret into the computers of their future victims with the help of disguised Trojan horse infections that exploit unknown and/or unpatched system vulnerabilities. The end result is that, by the time the user realizes their machine has been compromised, their data has already been made inaccessible with the help of the advanced encryption algorithm used by the virus. To make matters even worse, the encryption used by most modern ransomware viruses are way too advanced for any conventional decrypting software to break. Usually, the only way to remove the encryption from the locked files is by using the matching decryption key which, of course, is held by the hackers who want you to pay a ransom to get it from them.

The ThunderX virus

The ThunderX virus is a dangerous file-targeting type of malware designed to prevent you from accessing any of your most valuable files. The idea behind the ThunderX virus is to force you to pay money to its creators who will (supposedly) allow you to access your files.

For users who don’t keep any sensitive or important files on their computers that they cannot afford to lose, an attack from a ransomware virus wouldn’t be so devastating. The same can be said about those who have set up a backup location for their data and who make sure to update it regularly. However, in practice, it seems that most people do not fall in either of these two categories of users and instead do indeed have sensitive files stored on their machines without a proper backup for said files.

This is what makes ransomware attacks so devastating – they have the potential to “destroy” years’ worth of work, studies, or memories. This is why, when faced with such a virus, most users tend to despair and, if they can afford it, go for the ransom payment. It is important, though, to not act out of desperation and immediately pay the money because, in many cases, this may simply result in you losing a substantial sum without really getting what you need – the key for decrypting your files.

The ThunderX file encryption

The ThunderX file encryption is a complex procedure that renders your files inaccessible and that can only be reversed using the corresponding decryption key. However, the ThunderX file encryption may be circumvented via some alternative file-recovery techniques if you are lucky.

Before we show you some examples of such techniques, however, we advise you to complete the removal instructions posted below as it is important to first remove the ransomware before you try to recover any data or else any files you may manage to restore could get encrypted by the virus all over again.



Name ThunderX
Type Ransomware
Danger Level High (Ransomware is by far the worst threat you can encounter)
Symptoms Slow-downs and overall system instability could sometimes be caused by ransomware but other than that there are usually no visible symptoms during the encryption process.
Distribution Method Oftentimes, ransomware viruses are paired with Trojan horses – the Trojan sneaks in the computer using disguise and then silently deploys the ransomware infection without getting detected.
Data Recovery Tool Not Available

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).

Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    After you open their folder, end the processes that are infected, then delete their folders. 

    Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.

    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Type msconfig in the search field and hit enter. A window will pop-up:

    ThunderX Ransomware

    Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

    • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.

    Type Regedit in the windows search field and press EnterOnce inside, press CTRL and F together and type the virus’s Name. 

    Search for the ransomware  in your registries and delete the entries. Be extremely careful –  you can damage your system if you delete entries not related to the ransomware.

    Type each of the following in the Windows Search Field:

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
