Fd. Wild Tangent Folders in “C” Drive

Trying to get rid of “Wild Tangent” I clicked Start>>Search>>Files & Folders and typed in Wild Tangent. It came up with 17 with that name.
1 in Recycle
13 in zipped folders
3 files
I’m not sure if I should just leave them or if they are meaningless, get rid of them?? I’m a novice remember…
