File blocking

Enable file blocking to remove all files that pose a potential threat and to provide the best protection from active computer virus attacks. Blocking files is the only protection available from a virus that is so new that antivirus scanning cannot detect it. You would not normally run the FortiGate unit with blocking enabled. However, it is available for extremely high-risk situations in which there is no other way to prevent viruses from entering your network.

On a FortiGate unit with a hard disk, if quarantining is enabled for blocked files for the matching traffic protocol, the FortiGate unit adds the file to the quarantine list.

File blocking deletes all files that match a list of enabled file patterns. The FortiGate unit replaces the file with an alert message that is forwarded to the user. The FortiGate unit also writes a message to the virus log and sends an alert email if it is configured to do so.

Note: If both blocking and scanning are enabled, the FortiGate unit blocks files that match enabled file patterns and does not scan these files for viruses.
