ICE Cyber Crime Center Virus

Sony VAIO came into shop with the Windows Vista desktop blocked by a fraudulent screen requesting ransom. Here's what I did to the customer's satisfaction. 

•  Power on while tapping F8, but no back up to restore
•  Power on with F2 or F12 for BIOS set up
•  Change boot order: 1.CD, 2. USB, 3. HD
•  Power on with hiren boot USB. 
•  Copied bootmgr from D to C, but still locked out on restart.
•  Use hiren's Windows mini XP to back up user data.
•  Power on while tapping F10 and wipe C: to original factory.
• Advise user not to surf internet as administrator.
