Viewing the quarantine list
To view the quarantine list
1 Go to Anti-Virus > Quarantine.
The quarantine list displays the following information:
Sorting the quarantine list
You can sort the quarantine list according to status (infected or blocked), service
(IMAP, POP3, SMTP, FTP, or HTTP), date quarantined, time to live (TTL), duplicate
count, or alphabetically by filename,.
To sort the Quarantine list
1 Go to Anti-Virus > Quarantine.
2 Select a column heading in the Sort by list.
3 Select Apply.
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>.
For example, a file named Over Size.exe is stored as
3fc155d2.oversize.exe.
Date Quarantined The date and time that 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 Indicates if the file is infected by a virus, caught by heuristics, blocked by a
block pattern, or oversized.
Status
Description Specific information related to the status, for example, “File is infected 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
labels the file as EXP under the TTL heading. In the case of duplicate files,
each duplicate found refreshes the TTL.
Actions 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 specific file. Duplicate files (based on
checksum) are never stored, but an internal counter for each file records the number of
duplicates.
