Can't scan virus or spam mail

[Wilson Kwok]

Hello,
   
      I was uninstalled the old version and then installed the new version, but still
  can't scan viris or spam mail.
   
  Here is the maillog, you can see no message about scanning virus or spam, I already enabled clamav and spamassassin on MailScanner.conf
