Bitdefender used to be very good but they made a right hash of renewal this year. Firstly I renewed after several reminders but instead of renewing they treated me as a new subscriber with an expiry date set before a renewal would have kicked in. Following a conversation they rectified this problem but after many email attempts to contact them to sort out errors on my account I asked them to cancel my subscription so I could go elsewhere. Still no response so cannot rely on their promises. I would avoid this company if I were a new customer.
