[Mimedefang] clamav oddity

So I have MIMEDefang sorting out virus infected e-mails in
MD-Quarantine/virus and other spam under MD-Quarantine/spam (thanks to
David for the undocumented code, works great.) I see in my logs when it
quarantines a virus and tells me what it is and all. I have the filter
do a action_quarantine_entire_message() when it encounters a virus.
However, when I go back and run clamscan, or clamdscan on the qdir, it
turns up negative. If I download ENTIRE_MESSAGE to my local computer,
Norton AntiVirus kicks in and tells me the file is indeed infected. So
I know MIMEDefang is doing it's job properly (with the aid of clamav):
it scans, finds, and quarantines the virus. My question is, why is it
that when I go back and manually rescan the qdir folder, it comes up
negative? Case in point:
# clamscan
/var/spool/MD-Quarantine/virus/qdir-2004-04-30-00.47.19-001/SENDER: OK
/var/spool/MD-Quarantine/virus/qdir-2004-04-30-00.47.19-001/SENDMAIL-QID: OK
/var/spool/MD-Quarantine/virus/qdir-2004-04-30-00.47.19-001/RECIPIENTS: OK
/var/spool/MD-Quarantine/virus/qdir-2004-04-30-00.47.19-001/HEADERS: OK
/var/spool/MD-Quarantine/virus/qdir-2004-04-30-00.47.19-001/MSG.0: OK
/var/spool/MD-Quarantine/virus/qdir-2004-04-30-00.47.19-001/ENTIRE_MESSAGE:
OK
----------- SCAN SUMMARY -----------
Known viruses: 21304
Scanned directories: 1
Scanned files: 6
Infected files: 0
Data scanned: 0.04 MB
I/O buffer size: 131072 bytes
Time: 1.249 sec (0 m 1 s)
I download ENTIRE_MESSAGE, and it's reported to have Worm.Mydoom.H
in it, which is why MIMEDefang originally quarantined it for too (my
logs verified this.) So, where is clamscan failing, and why?
