Help with RSA-2048 crypto ransom virus
First off, I am sorry to hear about your circumstances. Unfortunately, the virus that you caught seems to be CryptoWall 3.0 or at least a variation of it. Therefore I am bringing bad news. As stated here it is not possible to decrypt or recover the files without paying these [insert swearword]. 

This is mainly through the nature of the encryption algorithm used, as the key used to decrypt your files is only known to the creators/distributors of the virus. 

For the future, make sure to have backups of all your data on a drive that is not connected to your computer and most importantly NEVER click on links or open attachments from E-Mails when you can't 100% verify the senders integrity.
