Bottom line: in an effort to protect their software against hackers, many legitimate customers (of which I am one) get software that refuses to install itself properly. I have used Norton since the days of DOS. After my latest experience, I will go elsewhere. There are other very good choices available. After years of being a loyal customer, they have lost me. I consider myself to be above-average in terms of computer savvy, for whatever that's worth. Beware of this software.
