Not detecting eicar in zipped form

[Barry Andersson]

Hi,

I ran Gavin's script to install MailScanner on my RaQ 4 and all worked
great.

I sent a eicar test virus and it detected and removed it. However when I
sent the same test virus in zip format it was not detected. Unzip is
definitely installed on the RaQ.

I'm using McAfee Uvscan as the virus scanner.

Any suggestions?
