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.
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.
