Unsubscribing from a podcast will depend on the software or feed reader that you are using but here are some general guidlines:
Select the undesired podcast (feed), in the software or feed reader that you are using.
Next, look for commands or buttons with "unsubscribe", "delete", "remove", "remove selected feed" or similar sounding text and carry out the action.
Sometimes simply selecting the feed and hitting the delete key may do the trick.
Note that unsubscribing from a podcast will not necessarily delete previously downloaded episodes and deleting the actual files may require further action on your part.
