Ransom.Crysis is Malwarebytes' detection name for a family of ransomware also known as CrySis or Dharma that targets Windows systems.
Users of infected systems will find a ransomnote on their desktop when the decryption routine has been completed. They may also notice that all their restore points are gone and that their files are no longer accessible because they have been encrypted and given a new extension.
Ransom.Crysis is ransomware that encrypts files on an infected system. Ransomware in general is a type of malware that prevents users from accessing their system or personal files and demands a ransom payment in order to regain access. Ransom.Crysis uses several methods to infect a system, it can be done manually by use of weak or leaked RDP passwords, by malicious mail attachments, and sometimes it is offered for download as an installer for a game or other legitimate software.
Ransom.Crysis deletes restore points by running the vssadmin delete shadows /all /quiet command. So if these restore points were part of your backup plan they could be lost if the ransomware has been running.
