reregistering Word doesn't help, then see

All of a sudden, I noticed that files I had saved in Word have been converted
to Word Pad documents. Even the icon indicating the kind of document in now a
Word Pad icon. Recently, using Word, I saved a document. Later on, when I
looked for it again, it was already a Word Pad document.
Did I made a wrong setting by mistake or has my computer been invaded by a
virus?
