Outlook 2013 Norton Internet Security slow to download emails

I understand full support for Office 2013 has not been released but I thought this should be out there to share with other users. 

 

I am running Win8 64bit and Office 2013 32bit with Outlook installed and with Norton Internet Security installed ver20.2.1.22. Current I am experiencing extremely poor email download speeds with email coming in at the byte speed not kb or MB but byte speeds. This has made Outlook unusable. 

 

I have found turning off both Email Antivirus Scan and Antispam resolves the problem. 

 

Symantec can you please resolve this problem as now I have resduced security.

 

Thanks.
