AntiSpam rule in Outlook Express

Norton's antispam feature automatically creates a message rule in Outlook Express that moves tagged messages to a newly created folder.  Unfortunately, it prevents the user from deleting that rule (in order to create a slightly modified one) or even adjusting it; commands are grayed out.  For example, I'd like to add "and mark these messages as read" to the rule that moves them to the new folder -- or maybe even change the name of the spam folder.  Any way to do this?

 

On another topic:  How is it that Norton -- unlike every other security program I've seen -- doesn't show up on a list of autorun/startup programs (e.g., on the msconfig list)?  How does it manage to start automatically when it's not on the list of the programs that do so?
