submitted file to Symantec

My Norton Internet Security 2011 recently notified me it had detected and removed a Trojan malscript!html with the type

dog[1].htm, I'm afraid being a nervy computer user I went into panic mode especially when I found it hadn't been deleted but placed in quarantine. I then submitted the file to Symantec using the option in Quarantine before removing it from quarantine history.I now have time for a more calmer reaction and have a few questions:

  1. Has removing the file from quarantine history completely eliminated it from my computer or merely stopped it telling me its there?
  2. What happens now to the submission I made to Symantec,can I expect feedback from them about the nature of the threat etc. or is it just used to develop future responses.
  3. What level of personal information is Symantec able to collect about me from my submission.
  4. Does anyone know exactly what dog[1].htm does on my computer
