This new malware first tries to remove a number of Windows services that are required for Windows Defender and Malwarebytes to operate successfully. Researches reported that AVCrypt seems incomplete because of major missing pieces. While it does contact a command and control server and encrypts files it doesn’t include any ransom instructions nor provisions for decryption. The delivery mechanism appear to be the standard methods seen in other ransomware including malicious spam, drive-by URLs, and pirated software.
