Those are generally Good Things that you want to keep; they allow the word to be broken if it falls at the end of a line. ("could¬n't" is a really bad one and should be avoided.) It generally means your Word settings have been set to "show invisible characters"--this can show all of them (soft hyphens, arrows for tabs, the ¶ symbol for ends of paragraphs, dots for spaces, and a few more) or it can be set to only show a few of them.
If there's a ¶ symbol on your toolbars, clicking it should make them go invisible. If not, under Tools-->Options-->View tab, the "Formatting marks" section shows which ones are set to be visible (when the "show all" button on the View toolbar is active).
If they're actual soft hypens, rather than the ¬ character (which you can get by holding the alt key and typing "0172" on the keyboard), they're formatting marks only, and they don't print or export, except as code, like paragraph marks or invisible table lines.
