Generality of CryptoWall Decrypter

CryptoWall Decrypter is an encrypting virus that does not block your whole screen but to ask for money to help decrypt your precious and valuable files. It belongs to ransomware and the ransom it calls for is 1.16BTC (about 500USD). CryptoWall Decrypter threatens that if no money submission is completed within the validity, the ransom will be doubled. So fat CryptoWall Decrypter aims at enterprises mainly as the data files are much more valuable, besides, the boss could afford the amount of money or more.

CryptoDefense Asks for $500 BitCoin Aiming at Enterprises! Help!

CryptoDefense is another encryption software in the wake of Cryptolocker. It employs almost the same way to encrypt the document and data on a target machine:
CryptoDefense acquires RSA public key from its remote control server when its vicious codes is injected by a supportive worm.

One of them can be deciphered by a private key which can be accessed on its controller and the other is in the hand of CryptoDefense’ author.

If one hands over money, the hacker would ask the victim to download certain browser and get the private key him/herself. Once the key it typed on the locked down computer, the hacker would remotely control the machine and use another key to finally decipher the documents, if the hacker keeps his/her words. Therefore, the decipher means has not yet been mastered. But it is necessary to remove CryptoDefense’ vicious code from the computer to prevent further damage.

Drivers regarding security utilities are also disabled by CryptoDefense; plus complex SHA shell, CryptoDefense is capable of hindering any modifications of its core files and data, so that the evil deeds can be guaranteed. When drivers, tools to communicate between hardware and software for a better operation, are disabled or maliciously modified, mechanical problems, dysfunctions and malfunctions would be incurred:
