When a USB drive stops showing documents and starts displaying shortcuts, it is safer to follow a clear sequence rather than experiment with destructive commands. The MAYUNDO name should only be applied when compatible indicators exist.
First precautions
- Do not open unexpected shortcuts or unknown scripts.
- Avoid plugging the drive into several computers.
- Record file changes, error messages and used storage space.
- Do not rush into formatting or deleting hidden folders.
Perform a broad diagnosis
Scan Windows and the removable drive. If multiple USB drives show symptoms, pay particular attention to computers they have all used. A report helps identify links among shortcuts, scripts and persistence.
Preserve before cleaning
If documents are critical and the drive appears physically faulty, stop attempting DIY repairs. For software infections, preserve safe copies of legitimate data and remediate only components identified as threats.
Verify the result
After remediation, rescan Windows and the drive. If symptoms return, document the recurrence. A scan without known indicators is useful evidence for that scenario, not an absolute guarantee.
