generating a plurality of attributes based on scanning the data for viruses, wherein the plurality of attributes includes a scan status and a version identifier that identifies a version of the third party software components.

9. The method of claim 1 , further comprising:

receiving an updated version of one or more of the third party software components from the third party vendor, the one or more of the third party software components being used for the scanning the data for viruses.

10. The method of claim 9 , wherein the updated version of the one or more third party software components includes an anti-virus scan engine and anti-virus definitions that are associated with a version identifier.

11. A computing device comprising:

a network interface to enable the computing device to communicate with one or more other devices of a clustered storage system;

a memory resource storing instructions; and

at least one processor coupled to the network interface and the memory resource, the at least one processor to execute the instructions to perform operations comprising:

receiving, from a client device via the network interface, a request for data stored in the clustered storage system including a plurality of virtual servers;

identifying a virtual server from the plurality of virtual servers based on a location where the data is stored in the clustered storage system;

retrieving on-access policy information associated with the identified virtual server and the location of the data in response to receiving the request for the data;

accessing one or more predetermined criterion specified by the on-access policy information;

determining that the data is to be scanned for viruses based on the one or more predetermined criterion; and

scanning the data for viruses, the scan using third party software components that are provided by a third party vendor.

12. The computing device of claim 11 , wherein the at least one processor executes the instructions to further perform operations comprising:

generating a scan flag based on determining that the data is to be scanned for viruses; and

generating one or more parameters that indicate a type of request for the data, the type of request corresponding to a read request or a write request;

wherein scanning the data for viruses is based on the one or more parameters.

13. The computing device of claim 11 , wherein the request corresponds to a request to access a file that includes the data.

14. The computing device of claim 13 , wherein the one or more predetermined criterion specifies that the data is to be scanned for viruses when the file that includes the data is stored in a predetermined file directory.

15. The computing device of claim 13 , wherein the one or more predetermined criterion specifies that the data is to be scanned for viruses based on a protocol in which the request to access the file is received, and wherein the protocol corresponds to either a common internet file system (CIFS) protocol or a network file system (NFS)protocol.

16. The computing device of claim 13 , wherein the one or more predetermined criterion specifies that the data is to be scanned for viruses when the file has execute permissions set for one or more permissions groups.

17. The computing device of claim 11 , wherein the one or more predetermined criterion is configurable by a user.

18. The computing device of claim 11 , wherein the at least one processor executes the instructions to further perform operations comprising:

generating a scan status based on scanning the data; and

storing the scan status with an anti-virus version identifier that identifies the third party software components.

19. The computing device of claim 11 , wherein the at least one processor executes the instructions to further perform operations comprising:

receiving an updated version of one or more of the third party software components from the third party vendor, the one or more of the third party software components being used for the scanning the data for viruses.

20. The clustered storage system of claim 19 , wherein the updated version of the one or more third party software components includes an anti-virus scan engine and anti-virus definitions that are associated with a version identifier.

21. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, causes the one or more processors to perform operations comprising:

receiving, from a client device, a request for data stored in a clustered storage system, the clustered storage system including a plurality of virtual servers and a plurality of nodes that are interconnected with each other over one or more networks;

identifying a virtual server from the plurality of virtual servers based on a location where the data is stored in the clustered storage system;

retrieving on-access policy information associated with the identified virtual server and the location of the data in response to receiving the request for the data;
