BTC virus Removal Guide
What is BTC ransomware virus?
BTC ransomware is a cryptovirus that encrypts files and marks them with .BTC appendix
BTC ransomware is a virus that demands cryptocurrency for locked data.
BTC ransomware virus is a cyber threat that locks users' data with the goal of extorting money. This virus first was spotted at the end of 2016. It is also known as BTCLocker ransomware and hails from the same family as an old Radamant ransomware. However, there are a lof other associations since the name matches with the one used by Dharma ransomware is known for having various similar versions with BTC in the file extension. In this case, cryptovirus appends .id-[victim's_ID].[firstname.lastname@example.org].btc file extension. After getting on the computer, each of these ransomware viruses starts encrypting files and makes them useless, then marks each encoded file by appending .BTC file extension. As soon as they finish this job, they deliver a ransom note called either BTC_DECRYPT_FILES.txt or IDR__BTC_DECRYPT_FILES.txt. These files are used to inform victims about the state of their computer and ask them the money.
|Ransom note||BTC_DECRYPT_FILES.txt or IDR__BTC_DECRYPT_FILES.txt|
|Ransom amount||0.5 – 1.5 BTC|
|Email address used to contact email@example.com; firstname.lastname@example.org; email@example.com; firstname.lastname@example.org|
|Distribution||Spam email attachments|
|Elimination||Use ReimageIntego to fix virus damage|
The creators of BTC ransomware virus provide three different emails for communication: email@example.com, firstname.lastname@example.org, email@example.com, and firstname.lastname@example.org. However, you should not consider writing and sending an email to them. They have prepared many blackmailing and psychological terror techniques to encourage victims to make the payment.
Unfortunately, there’s no guarantee that they will provide the necessary software for file decryption or it will work properly. Instead of thinking about this data recovery option, remove BTC ransomware from the computer. Then you will be able to recover your files from backups or using additional data recovery options presented at the end of the article.
The creators of BTC ransomware have been demanding from 0.5 to 1.5 Bitcoins 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.
Unfortunately, not many cybersecurity programs detect the main executable of this virus as malicious. It is possible that you need to enter the Safe Mode with Networking to scan your device using your chosen anti-malware. You can follow other instructions below to try other methods of virus removal.
BTC ransomware file can be falsely detected as safe by various AVs. However, these are the names this malware appears on some of the scan results:
- malicious_confidence_99% (D);
Some ransomware viruses are capable of deleting corrupted files; that’s why it’s crucial to get rid of any malware as soon as it announces about its appearance. This will not recover encrypted files, but protect your PC from other problems and infections. Therefore, researchers recommend initiating BTC ransomware removal immediately with the help of professional malware removal tools. We recommend using your antivirus and then additionally scanning the system with ReimageIntego or SpyHunter 5Combo Cleaner.
BTC ransomware is a program that gives a headache for people who have no backups. It is almost impossible to recover encrypted files after ransomware attack.
Malware spreading techniques include spam emails
Ransomware is not distributed using some unique proliferation techniques. Mostly, it has been delivered via malicious emails. 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 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.

- 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”.

How to prevent from getting ransomware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
