Step-by-Step CryptWalker Ransomware Removal Process

Brief Description on CryptWalker Ransomware

CryptWalker Ransomware appears to be a new variant of Jigsaw ransomware which was discovered in April 2016. However, this newly identified file-encrypting virus is still under development phase. Once it invades the targeted computer, the malware only enciphers the files stored in a single folder that can be easily found under 'Documents or Test'. At the time of writing this security article, it does not encode the files saved on other folders of infected computers. It only enciphers the files stored into the specific directory, just because it is in-development mode. The system files encrypted by CryptWalker Ransomware will be appended with a specific file extension reported as '.CryptWalker'. It might be possible that the ransomware is developed by the same threat actors behind Jigsaw ransomware, because it also appends the same file extension to every encoded files.
