THINKING CRITICALLY

1. A virus has attacked your hard drive and now when you start up Windows, instead of seeing a Windows desktop, the system freezes and you see a "blue screen of death" (an error message on a blue background).

   1. Try a data recovery service even though it is very expensive.

1. 2. Remove the hard drive from the computer case and install it in another computer.

1. 3. Try GetDataBack by Runtime Software (www.runtime.org) to recover the data.

1. 4. Use Windows utilities to attempt to fix the Windows boot problem.
