Hi, my wife - our whole family including me, we all have no other protection for years. Norton 360 degrees and the PC remains free (healthy) fours. Earlier in the first PC, s we had times one or the other protection, sometimes better and often not protective enough. Company anyway and yet completely different. But at some point you had reached its limits, where it started to hurt (to be just expensive). Simple, you will be awake! Made inquiries, listen to yourself. The result then and today. NORTON 360 degrees is indispensable for us. Had no more interference in our PC, s private or those that had to be used professionally. Five of these stars for the product. Full buy recommendation for this Norton 360 degrees, there have now been many years and there are so I still hope to be many more years. Regards Werner - Uwe
