Outlook 2010 freezes caused when norton internet security is running?????

Ok, I've been working on this problem all day.  Outlook 2010 and Norton Internet Security.

When I view a message from Paypal, Outlook 2010 completely freezes for about 20-30 seconds and then displays the message I just clicked.

 

This only happens when I view a paypal message all other messages are fine. Is this an anti-phishing setting?

 

If I turn of Norton Internet Security, the Paypal message displays instantly.  What is configured wrong with Norton. This is a new computer with Windows7 installed. I've only got a few apps installed at this point and was trying to get the email working.

 

This is not acceptable and it's obviously something caused by NIS.

 

Can you help?
