CryptoWall (you can also find it as CryptoWall 2.0 and CryptoWall 3.0) is a very dangerous ransomware that was released for generating the money. It is done by encrypting important user's files and then asking to pay a ransom for a code that could decrypt these files. It seems that this virus belongs to the same group of cyber criminals that is responsible for releasing such ransomwares as CryptoDefense, Cryptolocker, BitCrypt, Critroni, Cryptorbit, etc. If you are a Windows user, you should be especially careful because CryptoWall virus is capable of infecting all Windows versions, including including Windows XP, Windows Vista, Windows 7, and Windows 8. Right after it infects the system, it, it encrypts predetermined files and blocks the user so that he/she wouldn't be capable of accessing them. According to PC experts, the RSA 2048 encryption is used for that. In order to restore these files, you will be offered to pay a ransom of $500. In most of the cases, it should be paid in Bitcoins and the payment should be transferred via Tor (anonymous web browser). This money transfer method is usually used by hackers and cyber criminals in order to hide their identity.
If you are seeing a warning message, which is titled 'CryptoWall 2.0' or 'CryptoWall 3.0', then you are dealing with its updated version. CryptoWall 2.0 was updated in the end of 2014. After these updates, it is capable of generating unique payment addresses for each of the victims, it has its own gateways to TOR and was also filled with the secure deletion method that doesn't allow to use recovery tools while trying to decrypt important files. Cryptowall 3.0 was released in January, 2015. It seems that it it capable of encrypting new file names (HTML, PNG, TXT, URL), it has new gateways to TOR and an increased ransom deadline.
