How to Recover Hidden Files and Folders from USB Drive After Virus Attack

The Problem: Missing Files After Virus Attack

Have you ever plugged in your USB drive only to find that all your important files and folders have mysteriously disappeared? Don’t panic! In most cases, your data isn’t actually deleted – it’s just hidden by malicious software or viruses.

When viruses infect USB drives, they often hide your original files and folders by changing their attributes to “hidden,” “system,” or “read-only.” This makes them invisible in Windows Explorer, even when you have “Show hidden files and folders” enabled in Folder Options.

⚠️ Important Warning: Before you consider formatting your USB drive, try the recovery methods below. Formatting will permanently erase your data!

Solution 1: Using Command Prompt (Recommended)

The most effective way to recover hidden files is using the Windows Command Prompt with the attrib command.

Step-by-Step Instructions:

1. Insert your USB drive into your computer and note the drive letter (e.g., E:, F:, G:)

2. Open Command Prompt as Administrator:
   • Press Windows + R
   • Type cmd and press Ctrl + Shift + Enter
   • Click “Yes” if prompted by User Account Control
3. Run the recovery command:

   attrib -h -r -s /s /d G:\*.*
   

   Replace G: with your actual USB drive letter

Understanding the Command Parameters:

• -h : Removes the hidden attribute
• -r : Removes the read-only attribute
• -s : Removes the system attribute
• /s : Processes files in current folder and all subfolders
• /d : Processes folders as well as files
• *.* : Applies to all files and folders

1. Wait for the process to complete - This may take a few minutes depending on the amount of data

2. Check your USB drive - Your files and folders should now be visible!

Solution 2: Using Windows Explorer

If the command prompt method doesn’t work, try this alternative approach:

1. Open File Explorer and navigate to your USB drive

2. Go to View tab and click “Options” → “Change folder and search options”

3. In Folder Options:
   • Go to the “View” tab
   • Select “Show hidden files, folders, and drives”
   • Uncheck “Hide protected operating system files”
   • Click “Apply” and “OK”

4. Check your USB drive - Hidden files should now appear (they may look faded/transparent)

5. Right-click on hidden folders/files → Properties → Uncheck “Hidden” → Apply

Prevention Tips

To avoid this issue in the future:

• Keep your antivirus software updated and perform regular scans
• Safely eject USB drives before unplugging them
• Avoid using USB drives on infected computers
• Create regular backups of important data
• Scan USB drives before opening files from unknown sources

When to Seek Professional Help

If these methods don’t work, consider:

• Using specialized data recovery software
• Consulting a data recovery professional
• The files might be genuinely corrupted or deleted

Conclusion

USB drive virus attacks that hide your files are more common than you might think, but they’re usually not devastating. The attrib command is a powerful tool that can restore your hidden files quickly and effectively. Remember to always try recovery methods before formatting, as formatting will permanently destroy your data.
