No commercial online re-installation of a Windows is feasible. If you
lost your "System Recovery DVD" you may purchase a replacement from
your computer's manufacturer for a nominal fee + shipping.

Your system seems to be infected/corrupted beyond lesser rescue
methods and although, yes, Windows Defender shows a failure, a format
the HDD and restore from your backup is probably called for.

If you lack a recent system backup, a "Flatten & Rebuild" approach
with your next System Recovery DVD is indicated. Hint - I would
reconsider the use of Norton 360 on your next build.
