Well viruses, most AV s just like fix the virus and not touch the file, but if the file itself is the virus it is usually deleted, moved to some where i forgot, or is just made unaccessible ( not sure about this one lol
)
Quarantine just restricts the access to the file, and if you want you can take out a file from there.
A usual AV asks what you want to do: delete, quarantine or nothing (in those cases [rare ones] when it's false alarm).
I support this method to the HP's AV!
lol if the file is not deleted it will be easily reinstalled by people, or even someone you dont want to have.
