Petya, a brutal piece of malware, surfaced two weeks ago. It's a mean bit of crypto-extortion that hits its victims where it hurts: right in your startup drive. Because it encrypts your master boot file, if attacked, not only will you be unable to start up your PC and not even access your startup disk. Eeesh. Fortunately, there's help. Leostone has come up with a tool that creates the password needed to unlock your startup disk. It's not all that simple, however.
