Solution
This error message is caused by the fact
that you have set an anti virus program, in this case Norton
AntiVirus, to scan all emails automatically.
Changing the settings within Outlook Express will not solve
the issue. You need to go to Norton and change the settings
there. To do this in Norton 2000
