Automatically put all my folders into a shortcut of my USB....

Hello,

Hello, I have this problem for a few days now. I think my laptop has a virus but I'm not sure yet. This is my problem:
When I insert and open my USB on my laptop, it will automatically put all my folders into a shortcut of my USB (example: Removable Drive (4GB):,) When I open it, my folders are still there. I formatted my USB 5x but it will always create a shortcut of my USB.
Does anyone know what the problem is? Thank you so much....
