Hello,

Try this 1.

Check whether the files are not in hidden mode. Follow the following steps.

Step 1:

Click on the below link and download the file "AutorunExterminator"

http://en.kioskea.net/download/download-11613-autorun-exterminator

Extract it --> Double-click on "AutorunExterminator" --> Plug your External

hard drive now.

This will remove the autorun.inf files from your External hard drive and also from

the drives.

Step 2:

Click on "Start" -->Run --> type cmd and click on OK.

Here I assume your External hard drive 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 : Replace the letter g with your External hard drive letter.

Now check for your files in External Drive.

Step 3:

After that, download the Malwarebytes' Anti-Malware from the below link

Update it --> Perform "Full Scan"

Note : Default selected option is "Quick Scan".

Good Luck.
