You can execute virus scanning at the desired timing.
Select [Security] - [Virus scan settings] - [Manual scan] in administrator mode of Web Connection (or in [Utility] - [Administrator] of this machine), and tap [OK].
To execute manual scan, you need to set [Regular Scan settings] to ON.
If a virus is detected by the virus scan function, a warning message will remain displayed on the [Information] screen. When you confirm the virus detection history in Administrator Settings, the warning message is cleared. For details on how to confirm the virus detection history, refer to Here.
