Hi
Welcome to Microsoft community.
I'm glad to help you.
Usually this happens when you don't uninstall the program completely. However, it may not be possible to navigate directly to the program's registry directory at this time.
My current recommendation is to recommend that you reinstall terabox once, then open the terabox settings interface, find the corresponding option (such as opening the shortcut in this computer), uncheck it to turn it off, and then check if the icon (ghost storage device) still exists in your PC. If the icon has disappeared, then you can uninstall the TelaBox program now. This icon (ghost storage device) will not continue to interfere with you.
If anything is unclear, please do not hesitate to let me know.
