A number of AV programs are now achieving 100% pass rates in ITW virus detection. For the average PC user, FOR VIRUS DETECTION ONLY, is this category the most important? Is he/she as well protected in using an AV which scores regularly 100% ITW detection but misses lots of other viruses in other categories e.g. zoo, macro, polymorphic, standard? Should we take any notice of the failure of an AV product to detect viruses if they are not in the wild?
