Hello
During the update Bitdefender downloads additional tools used by the update module in order for those definition to be properly installed.
The reals size is the one displayed near Signatures update.
Also, in some cases if the connection is interrupted for a second, that definition is downloaded one more time using another mirror.
Thank you.
