perhaps it wasn't Norton but one of those anti-virus warnings that prompt you to install something which turns out to be a virus or malware?
Try 'system restore' and roll back to before the download. Just type 'system restore' into the Vista search pane under the orb (start button)

also update Norton, if you can get it to connect, and then run a full scan
