Those are "nonprinting" characters, which are displayed if the ¶ button on the Home ribbon is turned on (or if the "Show all formatting marks" check box is checked in the File > Options > Display page). Click the ¶ button to turn it off, or go to the Options page and clear the check box and any other boxes that are checked in that group.

For an explanation of the various characters, see http://wordfaqs.ssbarnhill.com/NonprintChars.htm.
