Viewing the virus list
Note: If virtual domains are enabled on the FortiGate unit, antivirus features are configured
globally. To access these features, select Global Configuration on the main menu.
The virus list displays an alphabetical list of the current FortiGuard virus
definitions (also called AV definitions) installed on the FortiGate unit. The
FortiGate unit uses the virus definitions to detect and remove viruses, worms,
trojans, and other threats from content as it passes through the FortiGate unit.
View the entire list or parts of the list by selecting the number or alphabet ranges.
To view the virus list, go to AntiVirus > Config.
The FortiGuard virus definitions list is updated every time the FortiGate unit
receives a new version of the FortiGuard AV definitions.
The FortiGuard Center Virus Encyclopedia contains detailed descriptions of the
viruses, worms, trojans, and other threats that can be detected and removed by
your FortiGate unit using the information in the FortiGuard virus definitions.

Viewing the grayware list
Usually the FortiGuard AV definitions are updated automatically from the
FortiGuard Distribution Network (FDN). Go to System > Maintenance >
FortiGuard Center to configure automatic AV definition updates from the FDN.
You can also update the AV definitions manually from the system dashboard (go
to System > Status).
Grayware programs are unsolicited commercial software programs that get
installed on computers, often without the user’s consent or knowledge. Grayware
programs are generally considered an annoyance, but these programs can cause
system performance problems or be used for malicious ends.
The FortiGate unit scans for known grayware executable programs in each
enabled category. The category list and contents are added or updated whenever
the FortiGate unit receives a virus update package. New categories may be
added at any time and will be loaded with the virus updates. By default, all new
categories are disabled. Grayware is enabled in a protection profile when Virus
Scan is enabled.
