Adding message scanned info to outgoing email??

I have just purchased NOD32 after trailing it for a little while now and I am very impressed with it.

I have a small problem though. When I send a message, I have set it up so that it ads the following to the outgoing message:

__________ NOD32 EMON 1.1217 (20050914) information __________

The email was checked by the NOD32 antivirus system:
email with subject testing123123 dated 09/15/2005 18:51 - is OK
email with subject testing123123 dated 09/15/2005 18:51 - is OK

The problem is that it ads the same line twice "email with subject testing123123 dated 09/15/2005 18:51 - is OK"

Is there anyway to stop this from happening?

Thanks!
