Add AD detection on desktop app #264, #304

This commit addresses issues #264 and #304, where users were not
receiving error messages when script execution failed due to
antivirus intervention, particularly with Microsoft Defender.
Now, desktop app users will see a detailed error message with
guidance on next steps if script saving or execution fails due
to antivirus removal.

Key changes:

- Implement a check to detect failure in file writing,
  including reading the written file back. This method effectively
  detects antivirus interventions, as the read operation triggers
  an antivirus scan, leading to file deletion by the antivirus.
- Introduce a specific error message for scenarios where an
  antivirus intervention is detected.
