One user on the network occasionally get emails returned to him from an address that he did not send an email. The person who was originally slated for the email never receives their email. The emails are returned with an attachment that states "Your attachment "mail5692.pif" contained a virus: W32.netsky.Q@MM. It was deleted and replaced with this file. Even though we run Norton corporate with up to date clients I went ahead and ran netskyFIX and it did not find any problems. Could this problem be external? Any help please.
