how do i disable this NAV nagware

[Schadenfroh]

it wants me to renew my subscription but its expired, so annoying, how do i make it go away? what registry key?, there is no way to turn it off within NAV and my school wont let me uninstall it even tho the defenitions are a year out of date and they are to cheap to subscribe

There are illegal ways to get rid of it...

but i would really like to know the legit way if any..
