If your computer was used for online banking or has credit card information on it, all passwords should be changed immediately
to include those used for email, eBay and forums. You should consider them to be compromised

When a program quarantines a file or moves it into a virus vault, that file is safely held there
(and no longer a threat) until you take action to delete it. One reason for doing this is to prevent deletion of an essential file that may have been flagged as a "False Positive
". If that is the case, then you can restore the file. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure
When the file in the vault is known to be bad
, you can delete
it at any time.
