Norton 360 V20.2 blocking my incoming emails today Jan 4 2013?

I tried to read various postings but none answered the problem.  this morning norton decided to block my emails.  I first thought it was my server but I was getting the mails at my gmail account.  I reset Outlook 2007 3 times thinking it was the problem and then I did fine some comment to turn off Norton 360 incoming mail scanning.  Now I have my emails but obviously I would like to have that protection again.   Anyone else having this problem, suggestions appreciated.
