How to remove BtcKING virus and restore encrypted files

If you've encountered a ransomware and you're sure that it is the BtcKING program – in our guide you'll find help. We offer plain and efficient advice about BtcKING elimination and practicable manners to restore the spoiled information.

What is BtcKING

Let's find out, what we'd find if we look inside a ransomware? It is built upon a totally legal encryption algorithm which changes all files on customer’s workstation, so user can't use them in any way. That key is also encoded with another algorithm. In most cases, these manners are AES and RSA, which are known for their complicacy and reliability. The mentioned methods and the programs built upon them can be easily found in the Web, so scammers only need to develop protective techniques, to block an inlet to a program, and create the perfect control and update system. Some encrypting tools may function on their own, and fraudsters know of a new "client" not before he approaches them and transmits his money. Other ransomwares are highly active, and transmit data to thousands URL's, to confuse the researchers and throw them off virus’ track.



Ransomware sort is not significant, as the RSA and AES methods are very complex to hack them directly. It will take centuries to perform all needed calculations on a regular home PC or, possibly, 3-4 decades in case of usage of an industrial computer. The only way to beat a high-quality encrypting malware is to hack into it, or break into its server, to receive a master key. In some cases there is a breaker, able to cease ransomware's activity in full or to make it pass the infected computer. If someone finds such breaker for BtcKING, or develop a decryptor, we will update this article.


There are some things to check, until you can give in and await for a decryptor. As it is said above, scammers make errors, and some characteristics of your operating system might assist you to restore information.


  • If your system record has no administrator authorization – you can congratulate yourself. The thing is that your operating system replicates any data before they’re deleted or modified. Those files are called SVC, and BtcKING has the methods to erase them. If you're employing the usual profile – the OS asks for a confirmation at the very second BtcKING attempts to delete these copies. In case you saw such confirmation and declined it – then the copies are secure, and you might use a specialized tool to get back the data.
  • A backup is the sole totally effective way to recover the data, but you have to uninstall BtcKING before. Ensure that BtcKING is removed totally, because if it’s not – all information will be spoiled again, including those that are on a flash drive.


If all of these hints didn't work and you have no chance to restore your information – you have to eliminate BtcKING from your computer and wait until a decryptor will be developed.

How to remove BtcKING

As for the removal – you can't entirely avoid an automatic mode. This virus is incredibly sly and you will definitely pass some elements and then regret it (it may happen if you attach an outer drive with the backups to a not-totally-cleared device). It also conceals pretty good, so you literally can't eliminate it fully by hand. According to this, we have made a solid uninstall instruction that can help you to beat this issue. It consists of a few manual steps and one extra AV tool step.
