Virus scanning questions

Hello all,

        This bugs me for almost the entire morning. Appreciate some help.

Problems:
---------
        I intend to notify senders of viruses. I checked the log files (posted below), the clamav does the scanning and logged that it found viruses. However, sender never gets notified. The recipient still receives the message (w/ virus attachment) unaltered in anyway. 

        The header of the received message contradicts the log message. The log message says that it has detected a virus, but the header says that it's clean.

        Header of the scanned message:
        X-greenapple.com-MailScanner-Information: Please contact the ISP for more information
        X-greenapple.com-MailScanner: Found to be clean

        My entire etc/ config can be found at www.greenapple.com/~rrobin/mailscanner/etc [.dist files are the unmodified original config files ]

Platform
--------
Sendmail 8.12.10
MailScanner v. 4.30.3
Clamav 0.70
Fedora
