How to Remove Bit Cryptor Virus and Restore Encrypted Files

Bit Cryptor or BitCryptor is a file-encrypting ransom virus (ransomware) that encrypts your files using AES-256 encryption algorithm so they are not accessible and repairable without the unique encryption key. In order to get the key and decrypt your files you need to pay a ransom of 1 bitcoin which is currently about $240. It targets all version of Windows. Files stored on Network-Attached Storage (NAS) and other computers on the same network can be encrypted as well. Just like any other ransomware it scans your computer for data files and then encrypts them silently in the background. Most users probably wont even notice anything suspicious. Once the ransom virus has encrypted your files it will display a Bit Cryptor program that contains instructions on how to get your files back. As you can see, it has a countdown clock and apparently the ransom cost will increase if you wont pay on time. Each victim has a unique bitcoin payment address. Cyber criminals allow you to decrypt one file for free.


You know as well as I do that as we all spend increasingly large portions of our waking lives working, playing, shopping and browsing online, the higher the risks of contracting a computer virus or being infected by ransomware are. There is big money to be made in the cyber crime industry and malicious programmers are creating online attackers that are now more sophisticated than ever before. Its like watching a dog chase its tail, watching antiviruses and malicious software play this endless game of outsmarting each other with their creations. But where does that leave us – the people who rely on the internet to earn money, relax or simply keep our busy lives in order? Well where were left is in the position of now having to be increasingly alert if we want to defend ourselves from becoming yet another faceless victim in the online war.

But the issue is that because the two sides of good and evil are constantly battling to stay one step ahead of each other, ransomware is constantly reinventing itself and finding new ways to cause havoc on our PCs or extort our hard earned cash from us. Bit Cryptor is a good example of how cyber criminals constantly improves their malware making it more sophisticated and dangerous. This particular variant, unlike most ransomware, block Task Manager and other program that can be used to disable it. As a result, it might be difficult to run anti-malware software and remove the ransom virus. Bclock.exe is the main process of this ransomware. Its usually located in C:Users[YourUserName]AppDataRoamingMicrosoftWindows folder. So, in case you cant open anti-malware programs or Windows tools, try to remove or at least disable the bclock.exe program first. If you cant do this using Task Manager, try Process Explorer. Theres also a filelist.locklst file which contains a list of all files encrypted. Dont delete it. Its not dangerous and besides you may still need it.
