When scanning the Project Gutenberg July 2006 DVD, I
noticed that certain archives -- .zip files -- caused
an error message to be displayed:
Zip module failure
There is no way to see whether the archive was
successfully scanned or not -- much less to see
whether it is infected or not.
Using WinZip v10.0.6667, I found that these archives --
333 in total -- were compressed using the "imploded"
compression method (whatever that might mean).
I am running Win2000-SP4, and ClamWin v0.88.5.
Considering the above, I feel that a major fault of
the ClamWin GUI -- needing immediate attention -- is
that, at the end of the scans, only the summary is
displayed; also, the scan log contains only the
summary of each scan; thus, after unattended scans,
the above message would have gone unnoticed.
Finally -- obviously -- Clam AV should include support
for alternative compression methods for .zip archives,
which consist by far the most commonly used archive
Below, is a sample output of the command line program
clamscan.exe, scanning a folder of the above mentioned
V:\etext91\moby.zip: Zip module failure
V:\etext91\plboss10.zip: Zip module failure
V:\etext91\world12.zip: Zip module failure
