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 167.

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 169.

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 226,

“File blocking” on page 227,

“Blocking oversized files and emails” on page 228,

“Exempting fragmented email from blocking” on page 228.

4Configure the messages that users receive when the FortiGate unit blocks or deletes an infected file. See “Replacement messages” on page 133.

5Configure the FortiGate unit to send an alert email when it blocks or deletes an infected file. See “Configuring alert email” in the Logging and Message Reference Guide.
