Once installed on both computers, and an initial full investigation but then I was surprised by the gaps has the Avira free. Meanwhile, were discovered more threats on my desk top and rendered harmless. Although the full investigation temporarily paralyze an older computer with Windows XP SP3, I am very satisfied with the HIS IS 2012. On the laptop with Win7 and Intel 5 processor runs everything even a little more supple and you can even surf on the side etc.
The mobile version I have installed on my smartphone with Android 2.3.4 now also and stelle there any impairment of performance determined. Threats have not yet been reported to me of this system and the possibilities of locating / locking the phone if lost or stolen are an excellent "gimmick" of the manufacturer.
Although I am very satisfied with the product, on the whole, and the difference between the two editions has been reimbursed, I have to deduct the delivery because of Probeme 1 star.
