1. An information processing system comprising:
- a storage system to store data;
a host computer to read and write a file configuring data to the storage system; and
a server computer to execute a process for detecting a virus for the file, the server computer including a database for managing virus patterns, the database having a last update time of a virus pattern indicating a time when the pattern of a virus was last updated;
wherein the storage system receives, from the server computer, the data of the file to store the data;
wherein the host computer is provided with file attribute information indicating an attribute of the file, the file attribute information including a last scan time indicating a time when the file was last processed for virus detection and location information indicating where the data of the file is located in the storage system; and
wherein the host computer determines whether a file is scanned or not on the basis of the last scan time in the file attribute information and the last update time of the virus pattern from the database of the server computer; and
if the last scan time is earlier than the last update time, the host computer asks the server computer to scan for virus in the file; and
if the last scan time is not earlier than the last update time, the host computer opens the file without virus scanning.

Abstract
Information such as a last scan time and a last update is encrypted and added to a file system that a CPU 132 on a host computer 13 manages. In accordance with the information, host 13 and a scan server work cooperatively. A scan is omitted for a file that is dated earlier than the last scan time, accelerating file access. When a file to be accessed is virus-infected, the user causing the virus infection is specified. Predetermined countermeasures can also be taken.

9. An information processing system comprising:
-
a scan server; and a storage system coupled to the scan server to store data, the storage system storing a last update time of a virus pattern indicating a time when the pattern of a virus was last updated; and a file server system including files to be accessed by a computer and file configuration information of the files, the file configuration information including a last scan time indicating a time when the file was last processed for virus detection and location information indicating where the data of the file is located in the storage system; wherein the storage system receives, from the scan server, the data of the file to store the data; wherein the file server system determines whether a file is scanned or not on the basis of the last scan time in the file configuration information and the last update time of the virus pattern from the storage system; and
if the last scan time is earlier than the last update time, the file server system asks the scan server to scan for virus in the file; and
if the last scan time is not earlier than the last update time, the file server system opens the file without virus scanning. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for processing information, comprising:
-
providing files to be accessed and file configuration information of the files, the file configuration information including a last scan time indicating a time when the file was last processed for virus detection and location information indicating where the data of the file is located in a storage system that receives the data of the file to store the data; providing a scan server which includes a last update time of a virus pattern indicating a time when the pattern of a virus was last updated; receiving an open request for a file; determining whether a file is scanned or not on the basis of the last scan time in the file configuration information and the last scan time of the virus pattern; and if the last scan time is earlier than the last update time, causing the scan server to scan for virus in the file; and
if the last scan time is not earlier than the last update time, opening the file without virus scanning. - View Dependent Claims (17, 18, 19, 20)
