Not disinfecting detected viruses found by clamav!

[Daniel Bowen]

Hello,
     I'm seeing the following message in the mail.log:

Jan 31 17:37:43 mail MailScanner[704]: New Batch: Scanning 1 messages, 1186 bytes
Jan 31 17:37:43 mail MailScanner[704]: Virus and Content Scanning: Starting

Jan 31 17:37:43 mail MailScanner[704]: Uninfected: Delivered 1 messages

yet the message arrive at it's destination, complete with "cleaned" signature, and the original virus containing attachment, as follows:

 --

 Mailscanner thanks transtec Computers for their support.

 [clamAV test signature was here, but deleted for posting to the list]

Does anyone have any hints as to how to get the thing to disinfect???

Thanks,
