Clone the default
Antivirus profile and edit it. To ensure
availability for business-critical applications, take
safe transition steps as
you move from your current state to the best practice profile. To
achieve the best practice profile, modify the default profile as
shown here and attach it to all security policy rules that allow
traffic. The Antivirus profile has decoders that detect and prevent
viruses and malware from being transferred over six protocols: HTTP,
SMTP, IMAP, POP3, FTP, and SMB. You can set WildFire actions for
all six protocols because the Antivirus profile also enforces actions
based on WildFire signatures.
