CryptoDefense Virus is a harmful infection. If it manages to enter your PC, it will ENCRYPT all of your files. If your system is infected by CryptoDefense Virus, then you will receive a message on the desktop that want you to pay a 500 USD/EUR equivalent in Bitcoins in a certain time frame. If you do not COMPLY, the sum will double. It claims that this is the only way to decrypt your files. There are REPORTS that more than 20,000 computers have already been infected by this malicious INTRUDER. The schemers behind this infection have not yet been discovered as all payments go through the Torn network. This makes it extremely difficult to find out who is responsible for this virus.

We use an application that uses .NET to decrypt data. “Every now and then” the application stops with and error related to RSA. The fix we have is to delete the files in c:\ C:\Users\<user>\AppData\Roaming\Microsoft\Crypto\RSA\S-1-5-21-2949292171-3919185263-3846045818-1156. This seems to work but its getting old. I would rather know what could cause the error so we can stop this hack. The only error we get from the vendors software is “invalid PARAMETER”. I’m sure “something” on the workstation changes to cause this just don’t know what. Any help would be appreciated
