Viewing and configuring the grayware list
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.
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.
To view the grayware list, go to
UTM > AntiVirus > Grayware
.
Figure 290: Sample grayware options
Enabling a grayware category blocks all files listed in the category. The categories may
change or expand when the FortiGate unit receives updates. You can choose to enable
the following grayware categories:
Adware
Block adware programs. Adware is usually embedded in freeware programs and
causes ads to pop up whenever the program is opened or used.
BHO
Block browser helper objects. BHOs are DLL files that are often installed as part of a
software package so the software can control the behavior of Internet Explorer 4.x
and later. Not all BHOs are malicious, but the potential exists to track surfing habits
and gather other information.
Dial
Block dialer programs. Dialers allow others to use the PC modem to call premium
numbers or make long distance calls.
Download
Block download programs. Download components are usually run at Windows startup
and are designed to install or download other software, especially advertising and dial
software.
