Protects your PC, online activities and your identity 100% it delivers award-winning protection against anything and everything that can harm your computer. I have been using this product for a few years and it works brilliantly. It runs in you background and will make all viruses either go completely away or quarantine them til you delete or follow the process recommended by Norton. It is usually the first software to get new virus definitions on new viruses made. I have never used any software that runs close to no memory and is very small to install. The prices of it is a little high but if you want world class protection then buy this program. It will make sure your computer is always secure. It will no let any of your information get loose and will keep your computer clean of viruses. I have talked with many people about this product at Microsoft and they all agree that it is the BEST Security Software you could buy. I recommend this product for ALL computer owners at all levels of knowledge and experience.
