Cryptowall Ransomware1

Cryptowall Ransomware

is actually malware and not a virus and will not spread through the network. All the DECRYPT_INSTRUCTION, DecryptAllFiles, how_decrypt, HELP_DECRYPT, HELP_TO_SAVE_FILES, and Help_Restore_Files files may be deleted as they are inert. The primary form of delivery is an email received by an end-user with a link or an attachment. The link is usually a Dropbox link and the file is usually a zip, exe, vbs, or txt file. This link/file is only for a downloader which installs and later downloads the Ransomware. 

The major problem with Crypto Ransomware is that it uninstalls itself after it's finished, leaving no traces behind. This makes it very difficult to get the actual file responsible for the encryption.

While we are continually updating our definitions for the Crypto Ransomware, there are many new variants each day. 

Currently, there is not an antivirus application available that is able to stop all its variants and it's an industry-wide issue at the moment.
