HELP ! Norton Confidential Problem - Information Guard and Antivirus question

Hi,

 

I've setup my Norton Internet Security 4.0 and everything went well.  The only proble I had was with confidential because I had Firefox 3.  I downgraded to Firefox 2 and everything seemed to go well.

 

The proble I have is when I cliked on Norton Confidential the Information Guard icon where you can see if it's enable or disabled has a stop sign with a cross saying error! . I try to enable it and the icon turns green for a second and comes back to error! .

 

How can I fix this ?  Please help me.

 

 Moreover I have a quick question regarding the anti-virus : I don't see any information or option to scan e-mail / mailboxes etc.. in Norton Anti-Virus.  I use Mail.app.  Is Norton integrated to scan incoming mail and attachments and outgoing mail ?

 

Thank you ,
