Suggestion for development team: Tune-up in OneCare should be more configurable and above all a user should be able to disable Tune-up. Anyone who is even moderately adept at using computers doesn't want to have magical cleanup happening to their system in the background. In fact, this is a good rule of thumb for all features of OneCare: there should be a straightforward on/off switch for each feature, such as there is for the firewall. The backup feature could definitely use an on/off switch as well.
