I am new to Bitdefender. I have just installed TS2013, since the installation I have noticed a couple of issues. When the computer is idle for a period it sometimes freezes completely (I need to hold down power button to force a shut down). If the the computer awakes, it will be very sluggish, then when I go to shut down it will hang up. Typically I will just force a shut down, last night I just left it figuring it will eventually shut off. To my surprise this morning the machine was still running, just hung up on the shutdown screen.
