"stay away!"0.5 starson by unhappy_with_Vonage
Pros: some protection but less then using chrome or safari, even firefox with good extensions.
Cons: 1) it uses up to 95% CPU. cannot do anything besides running PC tools
2) it's Norton, actually.
3) outsourced, incompetent customer support.
Summary: it doesn't makes sense to be protected on a computer you no longer can use as Norton (pc tools) takes over your computer.
