Subject: f-prot not catching mimail ?

As soon as I saw this email I terminaled into our SMTP server and saw
F-Secure grabbed the first mimail on July 27, a week ago.  The reason I was
so shocked by this email, is that in the 14 years I have been fighting
viruses, and have used everything, I saw multiple instances of Norton and
McAfee either not finding or not removing a virus.  But in all that time I
have never found one that got by F-Prot, then later F-Secure, which is why
it is the only AV we use from firewall to mail server to desktop.

If it sounds like I'm prejudiced, it's because I am.

Subject: [inbox] [Full-Disclosure] f-prot not catching mimail ?

I have a few copies of the mimail virus from yesterday that f-prot even
with its latest updates do not catch.  Both the Windows and FreeBSD version
fail to identify the two main variants I have got sent my way.

e.g.
avscan1% md5 *.DEF
MD5 (MACRO.DEF) = fc09bc864e62639bc3424e3425083421
MD5 (SIGN.DEF) = a5d8c14285b2c866e3261421f7f3a0d2
MD5 (SIGN2.DEF) = 12c403a108c398aeaca01a2a4da68de4
avscan1% f-prot -verno

MD5 (message2.html) = d7b72f9b8370aa3b132069a878b5b5c8
avscan1%

These are both caught by other scanners but passed by f-prot.  Anyone with
f-prot successfully identify this virus ?

avscan1% f-prot -virlist | grep -i mimail
Mimail.A@mm
JS/Mimail.dropper
avscan1%

I sent email yesterday about this to frisk, but just got a "we will submit
to the lab."  That was before their update so I wonder if they figure they
are covered.
