No update intervalls < 60 mins. possible (although shown in "last run" time stamp)

Dear community & eset mods,

although in scheduler I set the update interval to 15 mins., it sometimes took nod32 almost an hour to pick up the latest virus patterns, so I did some packet sniffing (a wireshark sample of successful communication with eset update servers can be found below)

if updates are set to occur e.g. every 5, 10, 15 or 30 mins., wireshark logs show no other update attempts than every 60 mins sharp.
if update intervall is set to e.g. every 61 mins., packet logs show an update attempt exactly every 61 mins ... it seems that update intervalls are hard wired to a minimum of 60 minutes, above that value the intervall can be changed effectively in increments of 1 min. !

Please also note that (if interval is set to 15 mins.) the "last run" timestamp in the scheduler window refreshes accordingly, indicating that the update does run every 15 mins. just as expected ... although wireshark logs cearly show that it does not !

Can anyone confirm this ?

I assume that's only a bug, otherwise it would be a case of offering non-existing software features and even reassuring their proper implementation to the customer ("last run" timestamp), so pretty unethical !!!

And just a final word: Security impact of different update intervals and hard wired minimum update periods (-> limit severs loads) are already being discussed in different threads ... thank you for observing that !

thanks & regards

EDIT: affected version NOD32 Antivirus 4.0.474.0 (64bit) on Windows 7 x64, all updates

 

Updates are not run in less than 60-minute intervals.

 

thanks Marcos, that confirms my observation.

But could you please elaborate on:

* where is this limit documented ?
* why are intervalls lower than 60 mins. offered at all ?
* most important: why are the "last run" timestamps suggesting that lower intervalls (if set) are executed as expected ?


any thoughts are welcome ...

 

why you want to update lower than 60 min !!??

imagine how much more connections to update servers if update could be set less than 60 minutes by all users in the world !

but........ you can update manually as frequently as you want, right clic on nodew icon, update
