[QUOTE="MacDefender, post: 878489, member: 83059"] I think if they believe most of the zero-days that have happened since the last snapshot are covered by just sending hashes up to KSN, then this is reasonable to not update the database. The doomsday would be something polymorphic/randomly generated (that can't be caught by hashes) but also can be caught by a good signature engine update, I suppose that would trigger a more frequent signature update. Overall I haven't seen a lot of cases where Kaspersky with cloud signatures falls behind what a hourly updating engine accomplishes, so their approach seems to be working. [/QUOTE]
