1. Go to Security Profiles > AntiVirus.

The default profile will be the one displayed by default.
If you are going to edit an existing profile, selecting it can be done by either using the drop down menu in the upper right hand corner of the window or by selecting the List icon (the furthest right of the 3 icons in the upper right of the window, if resembles a page with some lines on it), and then selecting the profile you want to edit from the list.
If you need to create a new profile you can either select the Create New icon (a plus sign within a circle) or select the List icon and then select the Create New link in the upper left of the window that appears.
3. If you are creating a new profile, write a name for it in the Name field.
4. Add or edit the Comments fields to more clearly describe the function.
5. Select the Inspection Mode.
6. For the Detect Viruses field, select either Block to prevent infected files from passing throughout the FortiGate or Monitor to allow infected files to pass through the FortiGate but to record instances of infection.
7. If you have a FortiCloud account, you can select Send Files to FortiGuard Sandbox for Inspection (Requires FortiCloud account)
You can select whether to send All Files to the Sandbox or Suspicious Files Only.
8. If you wish to use the Botnet feature, you can select Detect Connections to Botnet C&C Servers
Just like with the viruses, you can select whether to Block or Monitor the files that contain botnet or phishing connections.
