General configuration steps

Configuring antivirus protection involves the following general steps.

1Select antivirus protection options in a new or existing content profile. See “Adding content profiles” on page 219.

2Select the Anti-Virus & Web filter option in firewall policies that allow web (HTTP), FTP, and email (IMAP, POP3, and SMTP) connections through the FortiGate unit. Select a content profile that provides the antivirus protection options that you want to apply to a policy. See “Adding content profiles to policies” on page 221.

3Configure antivirus protection settings to control how the FortiGate unit applies antivirus protection to the web, FTP, and email traffic allowed by policies. See:

“Antivirus scanning” on page 280,

“Blocking oversized files and emails” on page 286,

“Exempting fragmented email from blocking” on page 287.
