There must be some problem, send the file to support @ eset.com with a link to this thread and we'll have a look into it.
Ok, done. I've used online tools (http://www.virustotal.com/flash/index_en.html and http://virusscan.jotti.org/) and it seems that NOD32 it's the only AV that does not recognise that threat
Since we haven't received anything yet, please re-send the file in an encrypted WinRAR/ZIP archive and protected with the password "infected".
Done; now something is changed. Here's the last report for the sample file from virus total: Antivirus Version Update Result NOD32v2 1.1764 09.20.2006 Win32/Netsky.Q
Have you scanned it only on virustotal and jotti's ?? If so, there could have been a problem with them. They are not alwasy so accurate, at least Jotti's.
