OVERKILL
$100 Site Donor 2021
And to add to this, just going from Symantec's comparison page, here are the things that plain old NAV 2010 does:
-Blocks viruses, spyware, Trojan horses, worms, bots, and rootkits
-Pulse updates every 5-15 minutes for up-to-the minute protection
-Intelligence-driven technology for faster, fewer, shorter scans
-Norton Bootable Recovery Tool repairs, restores and boots severely infected, unbootable PCs
-Leverages cloud-based online intelligence for real-time detection of threats
-Download Insight proactively warns of potential dangers in newly downloaded files and applications before you install or run them
-Guards against Web attacks that exploit software vulnerabilities
-Stops threats unrecognized by traditional antivirus techniques
-Provides clear insight into recent PC activities to help prevent slowdowns
-Optimizes application performance with one-click
-Free email, chat, or phone support†
-Automatically finds and fixes common PC problems
The extra $30.00 for NIS gets you:
-Defends against hackers with a quiet two-way firewall
-Filters unwanted email with professional-strength antispam
-Helps keep your kids safe online with parental controls (Microsoft Windows only)
-Helps secure and monitor your home network
-Automatically secures your PC when connecting to public wireless networks
-Block hackers from accessing your computer
-Blocks phishing websites and authenticates trusted sites
-Secures, stores, and manages login and personal information
-Prevents hackers from eavesdropping and stealing information as you type
-Identifies unsafe Web sites in your search results
Now, let's just go over these one by one:
1. Defends against hackers with a quiet two-way firewall
-Windows has a built-in "firewall" that does much the same thing. However, both are completely irrelevant if you are behind a router using NAT.
2. Filters unwanted email with professional-strength antispam
-This is useful. Of course if you have Outlook, you already have a SPAM filter, and if you use an on-line mail service like Yahoo, GMAIL, or Hotmail, it is irrelevant. But still not a "bad" item.
3. Helps keep your kids safe online with parental controls (Microsoft Windows only)
-Useful if you have kids I suppose. Of course you can also block this stuff at the router level with many inexpensive consumer-grade routers if we are just talking about URL and content filtering.
4. Helps secure and monitor your home network
-So does a router. And does a much better job.
5. Automatically secures your PC when connecting to public wireless networks
-So does Vista and Windows 7 with their Public/Work/Home network classification. And unless your computer is setup to be intentionally insecure, this really isn't useful.
6. Block hackers from accessing your computer
-So does a router, and again, does a much better job.
7. Blocks phishing websites and authenticates trusted sites
-I can see this being useful if you use IE. Chrome and Firefox (and even IE8) already have various levels of this type of protection built-in. And they are only getting better.
8. Secures, stores, and manages login and personal information
-See #7.
9. Prevents hackers from eavesdropping and stealing information as you type
-Normally keyloggers and the like fall under the "malware" umbrella, so I'm not sure why this is listed separately and it makes me curious.
10. Identifies unsafe Web sites in your search results
-See #7.
I personally don't see a lot of "advantages" that NIS has over NAV. Norton doesn't have the 2011 stuff listed on their website that I could find, so maybe it brings more to the table? But going by the 2010 stuff, I would pick NAV, a router, and Chrome or Firefox.
