[Exim] Exiscan and Trend Micro's antivirus

I'm trying to use exiscan with Trend Micro's antivirus.... I'm using Exim
v3x...

%scannerflags = (
                       'mcafee'     => '--noboot --unzip -r <DIRECTORY>',
                       'sophos'     => '-all -archive -ss <DIRECTORY>',
                       'nod32'      => '-heursafe
-basedir=/usr/local/nod32/nod3
                       'rav'        => '-all -listall -mail -smart -unzip
<DIREC
                       'antivir'    => '-v -z -allfiles -noboot -s -tmp
<DIRECTO
                       'custom'     => '-a -c1 -c2 -nl -r -s -u -y20 -sd -d'
                   );

%scannerregexp = (
                       'mcafee'     => 'Found',
                       'sophos'     => 'found',
                       'nod32'      => ' - ',
                       'rav'        => 'Infected: [1-9]',
                       'antivir'    => 'VIRUS',
                       'custom'     => 'Found'  <- not sure what to put in
here.
                    );

Can someone help...? I also can't get amavis to work... do I have to
upgrade to exim v4?

Thanks,

Peter
