No - at the moment it doesn't matter one way or t'other - but if EVERY message has a paper clip then I won't be able to easily find any message that does have an attachment.
They are not all "self" test messages - I get the attachment icon even on (test) messages from other senders - not just my own.
Still just curious......but just had a thought......the only machine to do this is running "Express", the other two (which don't get paper clips) are both running Outlook as part of Office 2003.
Mayhap the "snag" is in Express settings - not in AVG. Dunno.
