How to remove java ransomware (Virus Removal)

.java is the name of a file extension used by a variant of CrySiS ransomware. The .java extension is added to the end of filenames to files that have been encrypted by the ransomware. Once the files are encrypted and appended the new extension, they cannot be easily recovered. The ransomware will also drop a note file that essentially contains a ransom note that demands a fine/ransom to recover files encrypted by the virus.

Once the java virus has encrypted files, it will show the ransom note in attempt to gather a ransom payment from the victim. The ransom note states that your data was encrypted and describes how to purcahse a decryption key to decrypt files. Paying the ransom does not guarantee that the infection will be removed and won’t occur again in the future.

The ransomware is mostly spread by email spam message campaigns. The emails will contain malicious attachments that when executed will launch the malware across the machine.
