Did you know that the best antivirus out there is free..for life. All you need is a little bit of knowledge and this one:
Nothing else can protect you better.
You never enter any phone number nor personal details when you registered your product, how they know your number then?
Always ask questions and be suspicions, it's your data, your money, your computer and you need to know WHY!
The size of the picture is intended to print in your head that image when you do stupid things in internet.. no Antivirus can protect a stupid, careless user.
