Although it slowed down a bit starting the computer, it's perfect for the moment.
in addition this promotion, 5 users and 2 years of protection (730 days), thank you amazon.
Before I had Norton internet security inadvisable, like a sieve!
By cons I have had Kaspersky internet security software also very good.
At that price, I recommend to all Bitdefender, price / quality ratio: unbeatable.
