NOD in this case was first than other that release updates every 3 hours like Kaspersky. Congratulations to ESET

 

This is not true. KAV detect this virus at 16:30 CET. KAV was first AV detecting this virus. Look: http://www.eweek.com/article2/0,4149,1472436,00.asp and
https://www.wilderssecurity.com/showthread.php?t=20606.

KAV detect this file at 00:35 CET.

I have licensed for NOD32 and KAV.

These are spain time.

 

CET=Spain time

 

Here is an evidence that NOD32 updated the database much earlier (the time was in Slovakia which is GMT+1). It updates once an hour so the real update might have been released a bit sooner.

Thanks for the corrections, so hispasec isn't a good source of information
