I've used bitdefender for numerous years, pretty well hassle free until 2012.
Installed it yesterday, fired up this morning, no internet access, noticed bitdefender was grayed out and stated it was not responding, did a reboot, same issue, run the repair option, bitdefender started working although couldn't update and there was no internet access.
Totally removed TS 2012 and instantly gained internet access.
I'm now running 2011 again and, I must say, I'm not overly impressed with 2012 at the moment.
