Method 1 > Using command prompt

Open Command prompt as Administrator (Windows 7 or earlier: Windows key + R > Type CMD & ENTER, Windows 8: Search for “CMD” > Right click to CMD and Select “Run as Administrator” or right click overStart button and select “command prompt (Admin) “)

Connect Your USB storage (Pendrive/SD card) to your Computer.

Scan your storage with your antivirus program (Not compulsory but its effective) > If your antivirus found virus then delete it.

Type in Command prompt :  attrib -h -r -s /s /d <Your USB drive letter>:\*.* (See <Your USB drive letter> from My computer and then type it For ex, if your drive letter is “D” then the command is like: ” attrib -h -r -s /s /d D:\*.* “)

To know about this command Type ” attrib /? ” In CMD.

Now your Shortcut files again convert to normal files. Delete unknown files from your storage aftercommand process completes. I highly recommend you to after removing shortcut virus copy your USB data to your computer > Format the USB storage > Then again re-copy USB data back.
