"Good product, but the whole package expires."3.5 starson by EdEllks
Pros: Very fast processing of files. Mostly transparent activity. Doesn't noticeably slow your system down.
Cons: With their 2009 product, Norton started causing the ENTIRE NAV package to not load when your subscription expires. Previously, you simply could not download updates. Not so anymore. If you don't upgrade, you are without ANY virus protection.
Summary: I've used Norton for well over a decade on dozens of computers, and have not regretted it until recently. When I learned the hard way about the whole program expiring when the subscription was up, I started switching all of my computer and my clients over to another package when their current subscription is up. That's just horrible business practice.
I hope Symantec wakes up and changes this behavior, as they have an otherwise great product.
