Configuring Antivirus Scan for Inbound Files

Field	Description
ICAP server name	Type a suitable name for the ICAP server.
Host	Type the hostname or IP address of the server that hosts the ICAP server.
Port	Type the port number assigned to the ICAP server host.
Service configuration	Specify the virus scan service name of the ICAP server and the run-time parameter values to send to the ICAP server in the format: service name?parameter 1vaule&parameter 2vaule&parameter 3vaule&... Here, ... indicates any additional parameters that you might want to include. For example, the c-icap server's virus service expects the following parameters virus_scan?allow 204=onforce=on sizelimit=off mode=simple where: allow 204=on enables 204 (no content) responses outside previews for virus scan if the icap client does not support it. If the 204 response to the virus scan request is No modification needed, it indicates that no virus was found in the file. force=on Enables scan of the file even if its file type is not included in the srv_clamav.ScanFileTypes directive in c-icap.conf file. sizelimit=off Enables the virus scan service to ignore the srv_clamav.MaxObjectSize directive in c-icap.conf file. mode=simple enables the allow204 response only when no virus is found and an error message if a virus found. For more information about the parameters you can use, see your ICAP server documentation.
Scan buffer size per upload	Type the maximum data buffer size (in MB) that ActiveTransfer Gateway must store in-memory for an individual upload before streaming the file data to the ICAP server for scanning. For more information about how you can determine the scan buffer size, see Memory Configuration for Virus Scanning of Files Exceeding Scan Buffer Size.
Total scan buffer size	Type the maximum data buffer size (in MB) that ActiveTransfer Gateway must store in-memory for all uploads across all user sessions. When ActiveTransfer Gateway reaches this limit, it refuses to accept any additional uploads and the file transactions fail.
