Looks to me like you may have show hidden files/folders enabled and it scanned them. On phone right now so not sure if that folder is normally hidden or not.
The swsetup folder. I think that folder is usually hidden.
Here read this thread on HP Support.

It seems its only pertinent to HP systems. Its safe to delete. I thought it was a hidden folder by default until I checked my system this morning.
