Abstract:
1. A data processing system capable of accessing a plurality of storage devices, comprising: a processing unit for receiving an access request to any of said storage devices from an access request source, wherein the processing unit makes a first determination as to whether the access destination accompanying said received access request is a device that may already store data that has not been virus scanned (an infectable storage device) and makes a second determination as to whether said access request is a data read request or write request, and determines whether or not to virus scan the data of the access object according to said access request based on a result of said first determination and a result of said second determination wherein said processing unit manages separately virus scanned data written into a storage device and non-scanned data written into the storage device, and wherein said processing unit determines not to conduct virus scanning when the object data of said read request is said scanned data, even if a read scan mode of executing virus scanning has been set.
