On demand virus scan

A system comprising:

• a memory and a processor in communication with storage media, the memory including an archive tool and a virus scan tool:
• an object in communication with said storage media designated as non-recently accessed, wherein an access to an object includes read and write operations associated with the object and non-recently accessed defined by an interval parameter;
• wherein said non-recently accessed is determined by having time of a last access of the object that at least meets the interval parameter;
• said archive tool in communication with said storage media to archive said non-recently accessed object, the archive tool to convert said non-recently accessed object into an archived storage format;
• a-said virus scan tool in communication with said processor and said storage media to scan for a virus on all non-archived objects in said storage media while bypassing all archived objects in said storage media;
• and
• said virus scan tool to periodically search for presence of a virus in all non-archived objects, and to deny access of said processor to a non-archived object if a virus is present and to grant access of said processor to said non-archived object if a-no virus is absent from found in said object.

An article comprising:

• a non-transitory computer readable storage medium including computer program instructions configured to cause a computer to detect presence of a virus in an object in communication with storage media, comprising;
• instructions to designate a group of non-recently accessed objects in a storage device, wherein an access to an object includes read and write-operations associated with the object and non-recently accessed defined by an interval parameter;
• instructions to identify one or more objects within the group having time from last access of the object that at least meets the interval parameter;
• instructions to place the designated group of objects in an archive state, wherein all objects in said archived state are non-executable;
• instructions to scan for a virus on all non-archived objects in said storage device and to bypass all archive state objects during said scan in said storage device;
• and
• instructions to determine presence of a virus in an object, including granting access to said scanned non-archived object if it is determined that mno virus is ˜ found in said scanned non-archived object, and denying access to said scanned non-archived object if it is determined that a virus is present.

A computer system comprising:

• a memory and a processor in communication with an operating system and storage media, the memory including an archive tool and a virus detection tool;
• said archive tool in communication with said operating system to convert a non-recently accessed object into a compressed format, wherein an access to an object includes read and write-operations associated with the object and non-recently accessed defined by an interval parameter;
• wherein the non-recently accessed is determined upon time from last access of the object that at least meets a time interval parameter;
• said virus detection tool in communication with said operating system to scan all non-archived objects in said storage media for presence of a virus on a periodic basis, while bypassing all archived objects in said storage media, wherein said scan is limited to non-archived objects.

An article comprising:

• a non-transitory computer readable storage medium including computer program instructions configured to cause a computer to detect a computer virus, comprising:
• instructions to convert a non-recently accessed object into a non-executable format in said storage media, wherein an access to an object includes read and write operations associated with the object and non-recently accessed defined by an interval parameter;
• instructions to scan for a virus on all objects in an executable format while bypassing all objects in said non-executable format, wherein both executable and non-executable objects are present in said storage media during the scan;
• and
• instructions responsive to an access request to said non-executable format object, to restore said non-executable format object to an executable format, and to determine presence of a virus in said restored object.
