Just came across this forum. I am infected with this same virus. On March 27 all my .xls, .pdf, .jpeg, etc. files were encrypted. At statrtup, a process runs that tells you that you have illegal software on your computer and to visit
www.sopacrystal.com where they demand $130 for the key and decryption algorithm. In the README file left behind there are the instructions to visit sopacrystal.com and there is also a "key" I don't know if this is enough info but any help to decrypt my files would be aprecciated as I haven't backed up in a few weeks.
Also tried the recommend download from Kapersky but it didn't do any good.
Here is the contents of the README file:
Your files was blocked because of copyright violation, you can't access your files.
