I received a complaint from a relative, that their computer had crashed. Me, being the nice relative I am, agreed to take a look. They told me that just before it crashed they received a message from "the FBI" that said they were under investigation, and would have to pay to regain the use of the computer.
I tried to get the computer running again but it won't boot, BIOS won't even recognize that the hard drive is attached. It sees the CD/DVD drive, but not the hard drive. Of course when they purchased the computer they didn't make a recovery CD, so I can't even simply replace the hard drive.
First off. How could a virus/malware even achieve this?
Second. Is it possible to recover from this, or is the computer done for?
OS: Windows 7
