1. Norton 360 "Scanning message" popup hangs on last Outlook message sent. 2. Bounce popups problem

Norton 360 v5. These two problems have been happening since about a week ago.

 

1: Whenever I send messages from Outlook 2010, I get the small Norton "Scanning message 1 of n" popup for each message, but the last one always hangs. 

For example, this popup for the fourth message Scanning message popup hangs has been on the screen for about an hour. How do I get rid of it? How do I fix it? Is this a bug?

 

2. I use a third party Spam handling product called Mailwasher Pro. This bounces spam email very efficiently, based on text filter algorithms. Recently, I have been getting a popup for EVERY message bounced (and I get 5 to 15 junk emails every day):

I cannot believe that every bounced message has a virus. I have not seen these popups until lately, and I don't know how to suppress them.

 

OS is Windows XP SP3, 300+ Gb free disk space, 3Gb RAM memory, processor Pentium 4, 3GHz.

 

Help! Any ideas, anyone?
