How can I decrypt files after Bit Cryptor virus

Hello together,

yesterday, after I left my PC for a few minutes, I had a "new" Background on my Monitor "Your files have been encrypted   bit cryptor" and a Pop up window with a message to pay Money in a definite period of time to decrypt my files.

My Virus scanner removed this window from my Desktop (so I don't know how to pay for the key).

All files xls, doc, jpg are encrypted - and unfortunately my back up hard disk was connected and all files are also encrypted.

I read a lot of threads in the world wide web but nothing helps me - actually I am willing to pay for the key, but I have no idea how to do it.

I am really shocked because all files from many years are destroyed and the worst, all photos (children, Holiday, ...) from over ten years are encrypted!

Could anybody help me?

(sorry for my english - it is not my native language)

 

Thanks in advance!
