[Exim] exiscan...need help with regexp for cmdline antivirus…

I'm trying to use Trend Micro's vscan program for use with
exiscan.. exiscan is working fine now.... and to test virus detection, I
sent eicar test virus through my email system.... It wasn't detected....

$scannerex="/etc/iscan/vscan";

   %scannerflags = (
                       'mcafee'     => '--noboot --unzip -r <DIRECTORY>',
                       'sophos'     => '-all -archive -ss <DIRECTORY>',
                       'nod32'      => '-heursafe
-basedir=/usr/local/nod32/nod32 -all <DIRECTORY>',
                       'rav'        => '-all -listall -mail -smart -unzip
<DIRECTORY>',
                       'antivir'    => '-v -z -allfiles -noboot -s -tmp
<DIRECTORY>',
                       'custom'     => '-a -c1 -c2 -nl -r -s -u -y20 -sd -r
<DIRECTORY>'
                   );

scannerregexp = (
                       'mcafee'     => 'Found',
                       'sophos'     => 'found',
                       'nod32'      => ' - ',
                       'rav'        => 'Infected: [1-9]',
                       'antivir'    => 'VIRUS',
                       'custom'     => '\*\*\* Found virus'
                    );
