MailScanner not removing virus even though it was found?

[Paul Linton]

I have a brand new install of MailScanner/Spamassassin/McAfee.  Most
seems to be working fine, with the exception of virus removal.  MailScanner
calls McAfee and sees the virus, but then happily sends the message on, virus
and all, no warning to the recipient, etc.  Did I miss something in the .conf
file?

Here is a snippet of syslog:
Jul  8 22:32:50 xxx MailScanner[22175]: New Batch: Scanning 1 messages, 113172 bytes

Thanks for any pointers.
