Is it the actual Adobe Acrobat Reader program you want to remove, Delete, from your system?

For File use the File Manager that comes with the operating system. For Mac that is Finder. For Windows that is File Explorer (Or if you are using Win 7 or prior it is called Windows Explorer. Same thing, different first name).

For Windows Locate the files you want to delete (use the Search Function, type in the File name) and select and hit the Delete key.

For Mac basically the same thing except Right Click after Selecting and select Move To Trash. 

Then Empty the Trash or Recycle Bin, Respectively Mac /Windows.
