A user calls the help desk reporting that a laptop is not performing as expected. Upon checking the laptop, a technician notices that some system files have been renamed and file permissions have changed. What could cause these problems?

  • The file system is corrupted.
  • The laptop is infected by a virus.
  • The display driver is corrupted.
  • The file system has been encrypted.
    Explanation:

    Problems of system files being renamed and file permissions being changed without user knowledge are most likely caused by a virus. File system corruption would make the directory and files inaccessible. A corrupted display driver would prevent the laptop from displaying at all or it would display only VGA resolution.
