Are you in high spirits now that a solution has been found for this nasty ransomware?
For this solution to work, users infected with the Petya Bitcoin ransomware will need to remove the hard drive from their computer, and connect it to a non-infected machine. Once that is done, the user needs to use a particular web application to “conjure up” the password to restore file access. Doing so should allow for the decryption of the master boot file, and restore computer access.
