            Application No. 08/948,931                                                                        


                   A further understanding of the invention can be achieved by reading the following          
            claim.                                                                                            
                   1. A computer system comprising:                                                           
                         a storage subsystem including a storage medium and a controller,                     
                   the controller having a controller interface for controlling access to the                 
                   storage medium;                                                                            
                         a virus target structure stored on the storage medium;                               
                         a translation means for translating between logical requests for                     
                   access to the storage medium and corresponding parameters used in the                      
                   controller interface; and                                                                  
                         a detection means for detecting a virus using an alternate path to                   
                   the storage medium by detecting alteration of the correspondence                           
                   between logical requests for access to the virus target structure and the                  
                   corresponding controller interface parameters.                                             


                   Claims 1, 3-9, 17-26, and 31-36 stand rejected under 35 U.S.C. § 103(a) as                 
            obvious over IBM Technical Disclosure Bulletin, Artificial Immunity for Personal                  
            Computers,  vol. 34, no. 2 (July 1991) ("TDB") and U.S. Patent No. 5,881,151                      
            ("Yamamoto").
