Not much. Antivirus software has to constantly update its signature database that's used to identify and eliminate viruses and malware. The discrepancy indicates the difference in this database between 2008 and 2014. Jrabbit holeSS needs to get a grip. We're on a slow boat to China and there is no excuse, damnit.
I don't speak that language and can only apply common sense. Databases may increase number of viruses etc to search for, but this HD copy has been inactive since June 11, 2008. No new viruses to report.
Not sure, but I don't think your answer covers discrepancy.
