File blocking
Enable file blocking to remove all files that are a potential threat and to provide the
best protection from active computer virus attacks. Blocking files is the only protection
from a virus that is so new that antivirus scanning cannot detect it. You would not
normally operate 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.
