Description: Norton 360, developed by Symantec, is marketed as an "all-in-one" security suite. The package includes a personal firewall, phishing protection and the ability to detect and remove malware.
Separating this suite from Norton Internet Security is the inclusion of file backup and PC maintenance capabilities.

Antiviruses are a lot about personal taste. But what I've noticed of personal use, Norton is a horrible software. AVG made by Grisoft, even the free version, is much better.
I am on my third year of using AVG now, the free version. I have the full version on my laptop(downloaded).
