Why Bitdefender?
Because the highest rated, best of my views. Powerful without slowing down the PC. Protection of all data, whether banking, password Internet accounts, personal touch, smartphone protection with locking and location of the device in case of loss or theft and all that distance. Real-time protection of the mobile, simple to use etc ...
The list goes on ...
It is a protection that I use for almost 4 years (and if I add years where my parents pc protect us at home).
Great technical support.
In short, I strongly advice.
