How to remove Cryptolocker ransomware and decrypt .enc files

What is Cryptolocker?

Cryptolocker is initial version of ransomware-type virus. Although, this malware is no longer active, there are bunch of viruses based on it. And it’s no wonder why it motivated criminals to create similar projects. According to developers, their product got more than three million dollars from users who paid ransom. Today, we’ll consider one copycat form of it – Crypt0L0cker (TorrentLocker). Some newer variants even use initial name pretending to be original Cryptolocker ransomware. Following infiltration, it prevents access to your data using RSA-2048 encryption algorithm. All encrypted files are appended with .encrypted or .enc extensions. Then, 2 files, containing ransom message, will be created (DECRYTP_INSTRUCTIONS.html and DECRYPT_INSTRUCTIONS.txt). Unlike the old variant, the new one adds 6 random letters to extension of encrypted files, reinforcing all this by following files – HOW_TO_RESTORE_FILES.txt and HOW_TO_RESTORE_FILES.html.

DECRYTP_INSTRUCTIONS.html contains:
