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.
I found the same lack of detection, on Linux. Normally I save the suspect email message as a "UNIX mbox" file and feed that to f-prot; it then finds the attached ZIP within, and the files contained within the ZIP. However with Mimail, it does not detect the ZIP within the message. If I unpack the ZIP from the message, then the HTM from the ZIP, and finally the EXE from the HTM, then f-prot seems to skip all those except for the EXE, which it detects correctly. I cannot see anything "special" in the MIME structure of Mimail that would cause f-prot to miss the ZIP attachment (or maybe it is the structure of the ZIP that f-prot cannot unpack?).
