Hi.
I use f-prot and f-secure as virus scanning engines and I noticed that
sometime f-secure fails to report a virus. I use MailScanner 3.22.
The problem seems to be related to virus contained in files whose name is
parsed incorrectly (also from f-prot) and that are usually reported only by
the extension.
Here there is a recent example:
> Sender: <xxxxxxxxxx>
> Recipient: <xxxxxxxxxxxxxxxx>
> Subject: Have a nice Epiphany
> MessageID: g84N9HL09850
> Report: /var/spool/MailScanner/incoming/g84N9HL09850/.pif Infection:
> W32/Klez.E at mm
> Shortcuts to MS-Dos programs are very dangerous in email (.pif)
In this case the filename contained in the attachment was 4th[1].pif
but it was created in the quarantine directory as .pif
So this may be related to f-secure not scanning 'hidden' files, even
when --dumb is used.
A quick search in recent report messages (I use to cancel them), seems to
show that the problem happens mainly when the virus is contained in files
whose name contains '[' and ']'.
In all the other cases I get two reports, f-secure being the second engine to
be invoked.
> Sender: <xxxxxxxxxxxx>
> Recipient: <xxxxxxxxxxxxxxxxx>
> Subject: END RedMeasure V4
> MessageID: g85CHmL21381
> Report: /var/spool/MailScanner/incoming/g85CHmL21381/END.exe Infection:
> W32/Klez.H at mm
> ./g85CHmL21381/END.exe infection: W95/Klez.H at mm
