Kaspersky Lab's
RannohDecryptor tool will work for those infected with older variants of CryptXXX. However, Kaspersky's tool
will not work on CryptXXX 3.x variants...it will detect but not decrypt...see

here.

Trend Micro released a
Ransomware File Decryptor for victims of CryptXXX v1/v2/v3/v4/v5 but advises
files encrypted by CryptXXX V3 cannot be fully recovered to 100% (partial recovery)...read the section titled Important Note about Decrypting CryptXXX V3.

Dr.Web has advised
Files compromised by CryptXXX before June 2016 can be decrypted by Doctor Web.

Fabian Wosar (the head of Emsisoft's malware lab) has been regularly releasing new decryption tools. Kaspersky and Trend
Micro have been updating existing tools to include new ransomware variants. Dr.Web is not releasing decryptor tools for the general public but they are providing decryption service and support for victims.

Demonslay335 (aka Michael Gillespie) has been releasing decryption tools for new ransomware variants he is able to defeat.

Osiris Ransomware belongs to a batch of variants of the Locky Ransomware

Any files that are encrypted with the Locky (.OSIRIS) ransomware variant will be renamed with random alpha-numerical characters and have the
.osiris extension appended to the end of the encrypted data filename (i.e. 11111111--1111--1111--FC8BB0BA--5FE9D9C2B69A.osiris) and leave files (ransom notes) named DesktopOSIRIS.bmp, DesktopOSIRIS.htm, OSIRIS-[4_numbers].htm, OSIRIS-[4_numbers].htm
as explained
here.

Most crypto malware ransomware is typically programmed to automatically remove itself...the malicious files responsible for the infection...after the encrypting is done since they are no longer needed. That explains why many security scanners
do not find anything after the fact. The encrypted files do not contain malicious code so they are safe. Unfortunately, most victims do not realize they have been infected until the ransomware displays the ransom note and the files have already
been encrypted. In some cases there may be no ransom note and discovery only occurs at a later time when attempting to open an encrypted file. As such, they don't know how long the malware was on the system before being alerted or if
other malware was downloaded and installed along with the ransomware. If other malware was involved it could still be present so be sure to perform full scans with your anti-virus.

If your antivirus did not detect and remove anything, additional scans should be performed with other security programs like

Malwarebytes 3.0,
HitmanPro and
Emsisoft Anti-Malware. You can also supplement your anti-virus or get a second opinion by performing an

Online Virus Scan...ESET is one of the more effective online scanners.

Note: Disinfection will not help with decryption of any files affected by the ransomware.

Unfortunately, there is no known way at this time to decrypt files encrypted by any Locky variants regardless of the extension without paying the ransom...see this
