“Your files are locked !.txt” – this is what the victims of one of the first ransomware viruses ever to exist see after their computers have been attacked and their files are encrypted. CryptoLocker has stopped infecting users and many thought the ransomware was dead. However, there have been many copycats of the malware that proved us wrong by releasing yet another copied iteration of this ransomware. Being classic and all, the copycat virus named PCLock that pretends to be cryptolocker leaves behind two text files – one containing the ransom note “ Your Files Are Locked !.txt” and one containing the list of files encrypted by the virus, called “en_files.txt”. The Cryptolocker copycat malware this time gives approximately 120 hours to pay the ransom to a custom Bitcoin address and demands 0.65 BTC. Anyone who has been infected by this version of CryptoLocker should immediately focus on removing the malicious executable related to CryptoLocker copycat and trying to restore the encrypted files with alternative methods until researchers discover a solution for free decryption.
