If you are having a dubplicated files problem or not able to read your files inside your thumbdrive because of viruses. Follow the following steps. Perhaps this solution works for you.
Click on the below link and download the file “AutorunExterminator”
Extract it –> Double-click on “AutorunExterminator” –> Plug your flash drive now.
This will remove the autorun.inf files from your flash drive and also from drives.

Here I assume your flash drive letter as G:
Enter this command.
attrib -h -r -s /s /d g:\*.*
You can copy the above command –> Right-click in the Command Prompt and paste it.
Note : Don’t forget to replace the letter g with your flash drive letter.
Now press “Enter”.
Now check for your files in Flash Drive.
After that, download the Malwarebytes’ Anti-Malware from the below link
Update it –> Perform “Full Scan”
Note : Default selected option is “Quick Scan”.
