Remove .Crysis Ransomware (Virus Removal)

Crysis is ransomware virus that was created by attackers specifically to encrypt all files on the target computer. It demands for certain amount which basically serves as ransom before they will decrypt and bring back access to you.

Threat Summary

Brief Description:This ransom virus encrypts selected files on the computer and prompts user to pay for decryption key.


Crysis is a highly risky ransomware virus. Crysis can be covertly installed on its target computer. This virus locked your PC and prevents you from accessing all stored files. It extends the name of all encrypted files by adding the .crysis extension. After encryption, it displays a message containing email address and on how to regain access to all encrypted files.

Just like all other ransomware virus, Crysis demand to pay for certain amount in order to decrypt your files. This is in exchange for the private key that holds by malware authors. It says that merely paying the demand will let you regain access to your files. In order to pay the ransom, you have to contact crooks through email at Or you may use the email if you haven’t received any response from the first email within 48 hours. You may expect then from their response the amount of ransom, when to be paid, and how to pay it.

Please keep in mind that paying the ransom is not the key to decrypt your files. Cyber crooks only give you false hopes. Paying the ransom would not lead to your files being returned. It was just like spending your money for nothing. One thing is certain about Crysis virus; malware author will get the money and gives you nothing in return. This is how Crysis really works. Crysis was made to extort money from its victims.

Crysis is just the same among countless number of ransomware-type viruses which retrieval of data is absolutely not implemented as promised. They are all the same in terms of locking the computer and ends up only in collecting the ransom.
