After rebooting as asked by the Bitdefender updater, the antivirus module just reported and deleted without asking the pbcl.dll file from my Battlefield 3 Punkbuster instalation.
As this is a vital part of the PB instalation and I don't want my EA account banned for "evading" PB, please add an exception and update the definitions.
I'm sure I'm not the only only one with this problem.
I'm using Bitdefender Antivirus Plus 2012 v15.0.38.1605 and AV signatures 7272898.
The pbcl.dll is recognised as Trojan.Generic.KDV.644612.
