Viewing the quarantine list

1Go to Anti-Virus > Quarantine.

The quarantine list provides the following information.

File Name	The processed filename of the file that was quarantined. The processed
	filename has all white space removed. As a file is quarantined, it is 32-bit
	checksummed and stored on the FortiGate hard disk with the following
	naming convention: <32bit CRC>.<processed filename>
	For example, a file named Over Size.exe is stored as
	3fc155d2.oversize.exe.

Date Quarantined The date and time the file was quarantined, in the format dd/mm/yyyy hh:mm. This value indicates the time that the first file was quarantined if the duplicate count increases.

Service	The service from which the file was quarantined (HTTP, FTP, IMAP, POP3,
	SMTP).
Status	A color-coded status indicator:
	• Red: File is infected
	• Yellow: File caught by heuristics
	• Green: File blocked by block pattern
	• Blue: File is over size limit
	Fortinet recommends that you send yellow-status files to the FortiResponse
	Center as these files could contain a new virus or a variant of a known
	virus.
Status	Specific information related to the status, for example, the ‘File is infected
Description	with “W32/Klez.h”’ or “File was stopped by file block pattern”.
DC	Duplicate count. A count of how many duplicate files were discovered
	during quarantine. A rapidly increasing number can indicate a virus
	outbreak.
TTL	Time to live in the format hh:mm. When the TTL elapses, the FortiGate unit
	automatically deletes the file. In the case of duplicate files, each duplicate
	found refreshes the TTL.
Modify	You can delete or download the file. When you download a file, it is
	downloaded in its original format.

Note: In the case of duplicate files, all fields relate to the originally quarantined file except TTL, which is refreshed with every new instance of a given file. Duplicate files (based on checksum) are never stored, but an internal counter for each file records the number of duplicates encountered.

Sorting the quarantine list

You can sort the quarantine list according to status (infected or blocked), service (IMAP, POP3, SMTP, FTP, or HTTP), alphabetically by file name, by date quarantined, by time to live (TTL), or by duplicate count.
