[exim] Two Virus Scanners with exim

We are using exim 4.60 with standard configuration. We are using just
one virus scanner the following way:

av_scanner=cmdline:/usr/local/uvscan/uvscan --secure -rv --summary
--noboot --al
lole --analyse --mime --program --unzip
%s:password-protected|Found:(Found.*|is
password-.*)

Is there any way we can use another virus scanner (say clamav) without
changing the config a great deal. I think MailScanner provides
limitless opportunities - but at present we want to keep it simple.

Regards
