Another solid release from what I've seen, and (following-on from the 2009 version) this one doesn't cripple your PC when it's busy checking for viruses.
Remember, if you're currently running Norton Internet Security 2009, you can download the 2010 update free of charge, to use for the remainder of your subscription:http://www.hotukdeals.com/item/486796/new-norton-internet-security-2010-f
