Delete it from add or remove programs in control panel
Click start, then control panel. Then find 'Add or remove programs' (usually the first one) and double click it. Now find the programs and click uninstall
delete the free one and keep the payed for one until it expires, or which ever comes first? Are you sure the both av and one not antispyware?
Uninstall Norton here...............
