Thanks Christos,

after purging it form squid cache it work fine able to scan.
But now another problem when I try to download a zip virus file
http://www.eicar.org/download/eicar_com.zip

ERROR in the browser
The following error was encountered while trying to retrieve the URL:
http://www.eicar.org/download/eicar_com.zip

    ICAP protocol error.

The system returned: [No Error]

This means that some aspect of the ICAP communication failed.

Some possible problems are:

    *

      The ICAP server is not reachable.
    *

      An Illegal response was received from the ICAP server.
