Folder icons changed to shortcuts

I have two SanDisk flash drives (8 & 32 GB) and a 32 GB SanDisk Micro SD card and, as of yesterday, the folder icons have changed to shortcut icons that refer to "C:\WINDOWS\system32\cmd.exe F/c "start %cd%\sony.exe && %windir%\explorer %cd%\Extras". 'Extras' is just one of the folders on my 8GB flash drive. My files are still on all of my devices, but I cannot access them. After seeing the C prompt statement, I figured I am way out of my league. What do I need to do to restore my folder icons and directly access my files again?

My thanks in advance for your help.

The files have been corrupted, so I don't think they will be recoverable. Always use SD flash drives for temporary storage, and back up important files also on a DVD or on a second standard hard drive

This time, though, thankfully, they were recoverable. I did a *.* search and it showed that all of my files were still there, so I copied them to a new folder on my computer, formatted my flash drive, recopied the files to the drive, and the drive works as good as new. I also made several backups, just in case.
