Grayware

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 means.

The FortiGate unit scans for known grayware executable programs in each category you enable. The category list and contents are added or updated whenever your 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.

Grayware options

Grayware categories are populated with known executable files. Each time the FortiGate unit receives a virus and attack definitions update, the grayware categories and contents are updated.
