    I assume it was added to the last update issued a couple of hours ago.

    did submit the sample even prior posting here.

    and yes, it is in the update and now classified as Win32/Oficla.FV trojan

    what is worrisome though that is slipped under nod32's radar, not even advanced heuristics did detect it, considering that content of the file does not conceal its intention much. however, to be thorough and fair nod32 would have blocked the russian urls contacted to suck more stuff to the system
