Regarding the switch to a subscription based system for Bitdefender, here's what the Bitdefender website says:
Having this in mind, we put a brand new subscription based system in place for you.
What does this mean for you?
1.      No hassle with license keys
2.      A smoother experience when installing and registering Bitdefender on your home devices
3.      Better management of all your Bitdefender enrolled devices (Windows based, MAC systems and Android Mobile devices).
All I can say about these statements is that they are a bunch of crap.  License keys are not a hassle, the experience when installing and registering Bitdefender is a nightmare, and the management is full of problems.  Did they even test Bitdefender Central or just roll it out as soon as they were done coding?
I really wish I had read through this forum before I purchased my Bitdefender licenses; I would be successfully running some other antivirus software today instead of waiting on support to fix my subscriptions in Central.
And, what about the Tech Support Center?  I successfully log in, and when I try to view my open ticket, I'm told that action is not allowed.  Give me a break.
