Abstract:
1. A computer system, comprising: a storage system including a copying module which creates a copied storage area based on an instruction to create a copy of the storage area; a first computer which inputs and outputs data to and from a storage area in the storage system via a first path, wherein the first computer includes: an input/output module which inputs and outputs data to and from the storage area in the storage system via the first path; a memory which stores data inputted and outputted by the input/output module; and a processing module which processes data stored in the memory; a second computer which instructs the storage system to create a copy of the storage area, and judges, via a second path, whether or not the created copied storage area is infected with a computer virus, wherein the second computer including: an instruction module which instructs the storage system to create the copy of the storage area; and a virus check module which judges, via the second path, whether or not the created copied storage area is infected with a computer virus; and a path changing module, which is placed between the storage system and the first and second computers; wherein the first computer and the second computer are coupled via a network, and when the second computer judges that a file stored in the copied storage area is infected with a computer virus: the second computer sends, to the path changing module, an instruction to allow access from the first computer to the storage area in the storage system that is used by the first computer, as well as access between the first computer and the second computer; the path changing module allows, based on the received instruction, access from the first computer to the storage area in the storage system that is used by the first computer, as well as access between the first computer and the second computer, while prohibiting access between the first computer and other apparatus; the second computer sends, to the first computer, an instruction to delete a file stored in the storage area that corresponds to the infected file; and the first computer sends, via the first path, an instruction to delete the file stored in the storage area that corresponds to the infected file.
