When deciding about anti-virus software it usually comes two points. The first one is the the impact on the system and the second one the detection rate of the product. Both are heavily tested by magazines and online publications which should help in getting the best anti-virus product, but never did we see a vendor claiming that they actually make a system faster, till now. Today Norton issued a press release in which they state that their latest anti-virus products will boost the performance of Windows 8 with a whopping 50%.
According to Norton this is due to the fact that their products (Norton 360, Norton Internet Security, and Norton AntiVirus) are faster than Windows Defender, the anti-virus protection build in to Windows 8. Besides the speed increase, they also claim that Windows 8 with Norton products, instead of Windows Defender is 20% more safer. The claims are backed by a report from research company Passmark.
