Outlook Express 6 slow startup when Antivirus auto-protect is on

 

I just bought and installed Norton Antivirus 2012 yesterday.  With Auto-protect on, it takes about 1 minute for the Outlook Express splash screen to appear after I start it, and another 1 minute to see my folders.  If I turn Auto-protect off, it starts up instantly, as usual.  It also takes about 1 minute for the Toolbar to expand if I click on it, but only if Auto-protect is on.  For now, I have been turning Auto-protect off, starting OE, and then turning in back on.  I am then okay and have all functionality, unless I click on the toolbar.  What a pain!  Any ideas??

 

I am running Windows XP Media Edition an am current with all Windows Updates.
