1.6.1 This board comes from an uncertified manufacturer

hie I'm a newbie just bought an UNO R3 from DAFLABS 86/13 Sukh Sadan, Sion west, mumbai 400022 India ! board has that golden chip but IDE 1.6.1 for windows admin after connecting it shows the message:

"This board comes from an uncertified manufacturer.
We won't be able to provide any support if it doesn't work as expected."

how do i know if my board is original ?
