I Have Used so many Antivirus Products before like bitdefender / NOD32 / kaspersky etc. which is well known antivirus brands. but when I started using norton antivirus on one of my pc its working like a charm.
Running butterly smooth on window 8 no issue regarding virus slowdown, freezing of my computer its have fastest virus database update feature its stay always up to date to latest virus, malware threats
Symantec is well known company they good costumers service. I bought that product online so it came with some cool offers. I think no one need to Think Twice Just Try it Once And you will Never Try any other Antivirus.
