possible false positive?

after NOD32 updated today, get possible false positive on file for win32/PSW.Barrio.50 trojan in arcicons.dll from winace

a fully updated TDS-3 does not detect trojan in this file. This is an old trojan, surely it couldn't hide from TDS-3 and NOD32 would have found it long ago. Hence the false positive probability.

Howcan I send it to NOD32 for verificaton? I already submitted the file to TDS-3 via their file submission utility in TDS-3. Does NOD32 not have such a feature?

 

Hello,
I've few trojans that are detected by NOD and not by TDS-3, TH and TC, so it doesn't mean that's a false positive. It can be or doesn't can be.
You can send the sample in question to: samples@nod32.com
