The creators of BTC ransomware have been demanding from 0.5 to 1.5 Bitcoins[2] from their victims in exchange for their decryption tool. They will do their best to scare you once you contact them. For example, you can be informed on the ransom note, in particular, that a decryption key is the only way to recover your data. Then, you can learn that you will receive the key right after making a payment to them. However, you can hear nothing after paying because you are dealing with hackers.

Malware spreading techniques include spam emails

Ransomware is not distributed using some unique proliferation techniques. Mostly, it has been delivered via malicious emails.[4] It means that you should be extremely careful when opening emails, especially when dealing with emails from unknown people. Please, do not trust those messages claiming that you need to verify the invoice or similar document and stay away from the files attached to them.

Keep in mind that cybercriminals have been using various techniques to make these messages appear trustworthy and related to well-known companies. They can not only insert legitimate-looking logos[5] and signatures to the message to make it look credible. 

They can also create long stories why should the victim open the message and look at the contents of the attached file. If the user falls for such trickery and opens a malicious attachment, ransomware can easily enter the system and encrypt valuable files. To sum up, you need to be extremely careful with what you click on and think twice before opening email letters that come from people or organizations that you have no business with.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove BTC from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

Unless you have a data backup, it is impossible to recover data. However, there are some data recovery methods that you should try – they might help you to restore at least some of your files encrypted by BTC ransomware.

If your files are encrypted by BTC, you can use several methods to restore them:

Restore files encrypted by ransomware with Data Recovery Pro

Data Recovery Pro is a reliable software that can restore encrypted, corrupted, or deleted files. Use it as explained below.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by BTC ransomware;
  • Restore them.

Use Windows Previous Versions feature to recover your blocked files

You can use Windows Previous Versions feature to restore the most important files individually. Keep in mind that you can use this method only if System Restore function has been enabled before BTCLocker virus attack. This is how you should do it: 

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Use ShadowExplorer for data encrypted by BTC ransomware

If Shadow Volume copies remain untouched, you can employ ShadowExplorer

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Use Radamant decrypter to recover files encrypted by BTCLocker

If you are desperate to recover your encrypted files, you can try using Radamant decrypter. However, we cannot guarantee that this tool will work for you because it is designed for another ransomware virus.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from BTC and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
