Not to worry - many viruses spoof the senders address (The MAIL FROM field)
by using a random name on the infected machine. Presumably they have an
email you wrote to Birding-aus or some other one. It happens to me quite
often.  Still, I often run a virus scan and get an updated file, just in

 When a message is submitted to an SMTP (Simple Mail Transfer Protocol)
server it is tagged with a reverse-path.  The reverse-path is specified by
the sending application with the MAIL FROM: command  as outlined in the SMTP
RFC-821.  (Request for Comment 921) The reverse-path is the path the the
server  should use to communicate with the original sender of the message,
and therefore  the reverse-path is typically the e-mail address of the
sender (the from address).

The SMTP sever stores the reverse-path internally, not in the actual
message,  and forwards it with the message through any relay servers as
necessary until the
message encounters an error or reaches its destination. Since the
return-path is  not recorded in the actual message it is typical to add a
From: header to the  e-mail message which contains the address of the sender
and an optional  friendly name. i.e. "Joe Sender" <>.
Mail readers use the From: header to display who a message is from.

Obsesive techos might like to look at

best regards

I have had a couple of strange messages from Hotmail telling me that I have
sent out mail with a virus on it. I am a little suspicious as:

1 - My virus checker is updated daily and I have no viruses on the PC.
2 - I also have a firewall which should prevent anyone "hacking" into the PC
3 - The people it claims I sent the mail to I have never heard of and the
attachments I am, supposed to have sent do not exist on my PC. My suspicion
is that someone has "hijacked" my Hotmail account in some way and is sending
messages supposedly from me.

However - until I get to the bottom of this I suggest you treat any recent
mail from me as suspicious and make sure you run a virus checker.

I Am sorry for this - as I said my precautions are all as good as I can make
them and I really do not know what is happening here.
