That is interesting as this is the second Win32:Warezov-?? detection that I have seen in the forums today and neither are listed in the virus database, very strange. The last Win32:Warezov-O? ones listed are -OW, -OX and -OZ, but no -OY.
So there would appear to be a slight imbalance in the signatures and virus database, perhaps they don't update the virus database at the same time as the VPS.
