File pattern<br />

AntiVirus<br />

File pattern<br />

Configure file patterns to block all files that are a potential threat and to prevent<br />

active <strong>com</strong>puter virus attacks. Files can be blocked by name, extension, or any<br />

other pattern. File pattern blocking provides the flexibility to block potentially<br />

harmful content.<br />

Note: File pattern entries are not case sensitive. For example, adding *.exe to the file<br />

pattern list also blocks any files ending in .EXE.<br />

For standard operation, you can choose to disable File Pattern in the Protection<br />

Profile, and enable it temporarily to block specific threats as they occur.<br />

The <strong>FortiGate</strong> unit blocks files that match a configured file pattern and displays a<br />

replacement message instead. The <strong>FortiGate</strong> unit also writes a message to the<br />

virus log and sends an alert email message if configured to do so.<br />

If both File Pattern and Virus Scan are enabled, the <strong>FortiGate</strong> unit blocks files that<br />

match enabled file patterns and does not scan these files for viruses.<br />

Note: If virtual domains are enabled on the <strong>FortiGate</strong> unit, antivirus features are configured<br />

globally. To access these features, select Global Configuration on the main menu.<br />

you want to see.<br />
