Seconded. ClamAV has become almost completely useless since the
Sourcefire and then Cicso acquisition. It's a fine engine, but signatures
On our hosted anti-spam service, we outright block executables as well
as executables contained within archive files like ZIP, ARJ, .tar.gz, etc.
If you want to do this, see the "lsar" package that can scan many types
of archives and extract filenames. It's packaged with Debian and home page
