Any folder copied to my Flash/memory card becomes a shortcut?

Question

When I copy any folder to my memory card, it becomes a shortcut and the attributes of that folder changes to protected operating system files (hidden). I've formatted my memory card completely, have scanned it using two antivirus programs but the problem remains the same. Can somebody solve this problem that my folder's shortcut is not created when I paste into my memory card. Because the hidden files are not accessible in phone.

Additional Details:

If there is virus. How to delete that virus, I've scanned it with two antivirus programs (Microsoft Essentials and AVAST Free). I've formatted that as well but no benefit.

Solution

Here is the solution:

f you did not format your flash drive, then check whether the files are not in hidden mode.

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

Here I assume your pendrive as G:

Enter this command.

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

Note : Replace the letter G with your flash drive letter. Now check for your files in drive.

After that, download the Malwarebytes' Anti-Malware from here:

Update it --> Perform "Full Scan" 

Note: Default selected option is "Quick Scan".

I have seen this behavior before, it is a virus, specifically a rootkit. Run tdsskiller to find it. If i recall correctly the folder shortcut icon is actually an executable file to spread the virus.

@RichieFrame Experience is a valuable thing. This sounds like key information for the OP. Why not post this as an answer and give a link to any information you have on it?

Unfortunately, I no longer have any details on this, i was a while ago, and I believe it was a rather old rootkit at that time, if I can find any info I will definitely answer it

It might be better to include Richie Frame's comment in your answer. Now it's not clear why you are jumping to rootkit.
