It is a sad day today for me since my computer was suddenly hit by a ransomware called ThunderCrypt. I did not realize its coming until I saw the notification popped up on my desktop. It encrypted all my personal files and required me to buy the private key to recover my files. This is my first time to get attacked by ransomware and I am really afraid of losing my files forever. What can I do now? Please give me some suggestion.
Ransomware is a type of fearsome computer threat that almost PC users want to avoid. However, sometimes even though users have safeguarded their machines with an excellent antivirus program, they may get attacked by ransomware, having their important files encrypted and being threatened to lose their files permanently if the required ransom isn’t paid. But it should be noted that, paying the ransom may not be able to get your files back, and this will encourage more ransomware attacks. Therefore, we highly recommend you get rid of the ransomware that has infected your PC first and then try other ways to restore your files.
SpyHunter is recommended to remove ThunderCrypt ransomware. It is a professional malware removal tool which can detect and remove various types of malware on your PC.
ThunderCrypt is another strain of ransomware that attacks computers and encrypts files by using advanced cryptography for ransom. Research shows that this ransomware was identified in the first week of May 2017. It targets many types of files from different directories, including Adobe documents, Microsoft Office documents, video files, audio files, images, archives, spreadsheets, compressed archives, zipped folders and others. It encrypts them using the RSA-2048 encryption algorithm. Those files encrypted will be renamed and become inaccessible without a private key. The cyber hackers behind this ransomware require the victims to make a payment of 0.345 Bitcoin (about 648 USD) in exchange for the private key. If the payment is not paid before the deadline, the private key will be erased from the server where it is stored and the victims will lose their encrypted files forever.
Below is a screenshot of the ransom note which will be displayed on the victims’ computer desktop after the ransomware gets installed on the target computers and finishes the file encryption.
How Does the Ransomware Enter Your PC?
Most ransomware spreads by means of spam emails. ThunderCrypt is no exception. Its authors send thousands of spam emails to random email users. The emails contain messages of different topics, attempting to lure the recipients into clicking on the malicious attachments. For example, a user would receive an email containing subject like “invoice” and an attached file (actually it is a macro-enabled document). Once the user is scammed and opens the attachment, he will trigger the downloading of the ransomware.
Besides, ThunderCrypt can be distributed through fake Adobe Flash player update. Users may be shown a popup window, requiring them to install the latest version of Adobe Flash Player; however, it is a fake update file which acts as an installer for the ransomware. Once the update file is downloaded and launched, the ransomware will be activated and start performing its malicious activities on the victims’ computers.
Should You Pay the Ransom?
We do not recommend paying the ransom because there is no way to be sure that the cyber hackers will give you the private key after taking your money. It is possible that you lose both your personal files and money. Besides, paying the ransom will only breed more ransomware attacks.
Therefore, we suggest that you do not pay the ransom. Instead, you should quickly get rid of ThunderCrypt ransomware and use other methods to restore your files.
ThunderCrypt Ransomware Removal Instruction
At the mention of ransomware removal, you may think of system restore and antivirus program. Indeed, system restore is a Windows feature that can help fix certain types of computer problems, like crashing, blue screen of death, and malware infections. However, ThunderCrypt will delete the system’s restore points upon its installation, so this method cannot be used to delete the ransomware. As the ransomware can hide its traces deep in the system, manual removal is also impractical for general PC users. Therefore, we highly recommend using an advanced anti-malware program to perform the removal of ThunderCrypt ransomware.

Precaution Is Better Than Cure
Ransomware uses email scams and take advantage of vulnerabilities found in your operating system, web browsers and other software to access your computer. It can encrypt all important files stored on your hard drives and demand ransom for recovery of them. The ransom can be so high that you cannot afford or are unwilling to pay. Therefore, it is best for you to take preventative measures against ransomware. Here are a few tips to help keep you away from the ransomware or avoid being threatened by it:
- Making a backup of your important files is the best solution in a fight against ransomware. If you are unluckily hit by a file-encrypting ransomware, you no need to worry – you can just remove the ransomware and restore your files from the backup. But make sure that you back up your files to an external hard-drive or any other backup appliance. Besides, if you have websites, do not forget to back up the website databases, since some ransomware will also target websites.
- Ransomware often attacks your computer by exploiting system holes and vulnerabilities in your software. So, make sure you use legitimate version of operating system and software, and keep them updated regularly. You can open Control Panel and go to Windows Update to see if the machine is set to automatically install updates. If not, configure it immediately.
- Install a reliable anti-malware program and update it regularly. Besides, ensure you Windows firewall is running when browsing the Internet. With an anti-malware program and firewall running, you can block 97% malicious attacks and save you much trouble.
- Configure the spam filter to block attachments with suspicious extension like .exe to restrict access to spam emails which could bring ransomware.
- Ransomware often uses macros to attack your PC, so please disable macros on your entire network. You can use the new blocking feature in Office 2016 and disable it via a Group Policy or on an individual basis.
- Follow the safe surfing rules. Do not visit unknown or trustless websites; be careful of any window that pops up out of nowhere and requires you to download and install updates for Adobe Flash Player or your web browsers; avoid clicking on any questionable links or adverts when browsing the web; download software only from the trustworthy sources, if possible, go to the official websites to download the software you need.
Cyber hackers are inventing new ways of attacking your computer every day. Your computer can be the target of ransomware and other types of malware if you are not careful enough.
