Notes about the _CRYPT file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The _CRYPT file type is primarily associated with 'Virus.Win32.Gpcode.ak'. Gpcode.ak encrypts files with various extensions including, but not limited, to .doc, .txt, .pdf, .xls, .jpg, .png, .cpp, .h and more using an RSA encryption algorithm with a 1024-bit key. After Gpcode.ak encrypts files on the victim machine it changes the extension of these files to ._CRYPT and places a text file named !_READ_ME_!.txt in the same folder. In the text file the criminal tells the victims that the file has been encrypted and offers to sell them a decryptor. Anti-virus companies suggest that you NOT turn the infected computer off and that they be contacted using another computer to assist you in an attempted decryption.
