Hello, I recently reinstalled my operating system and after looking over my "Local Disk (C:)" I had some questions. There's a few things listed under (C:) that I do not know what they are. Some of the things are: (Qoobox, Config.msi, and msiinv). I wanted to know if I need these and if I can delete them? How should I go about deleting them safely so they do not come back? I'm posting a screenshot of my (C:) drive so you can see them all and figure out what I should do. Thanks
