If you've plugged in a USB drive or SD card and found that your files are missing and replaced with shortcuts, your USB drive has likely been infected with a shortcut virus. Luckily, your data still exists—it's just hidden by the virus. You can remove the virus using a free tool like UsbFix or by running some commands at the command prompt. Once the virus is removed from the flash drive, do a full scan of your computer using you preferred antivirus tool before reconnecting the USB drive.
