Question about the virus vault in Norton 2009

I have the following question regarding Norton AV 2009

 

A heuristic virus was detected on my system and automatically placed in quaraintaine.

 

But something confusing is going on:

Norton says the virus was deleted and no other action is required.

However: the virus is still listed in the quarantaine/virus vault.

When I click on 'options' there is no possibility that allows me to remove it from my pc altogether.

 

Basically Norton gives me 2 opposing messages: virus was deleted versus virus is in the vault.

Anyone knows how this works?

 

I hope my information is complete, as I am writing this from memory (working from a distance) and am doing a rough translation from the Dutch version.
