We pass on the occasional minor spelling issue, as long as it doesn't get in the way...but really, if you want an on-topic reply, take the time to make it easy to read and show the reader you have taken the time and care about your reader.
Maybe look at my reply to your other thread. Try posting a bit more in existing threads rather than starting a bunch of new ones. I find it's always a good course of action on any forum I have recently joined, regardless of the forum's content.
Maybe you're totally on the up and up and I hate to be that person… and I'm kind of surprised no one seems to have said anything yet, but… you're a very new user and the only things you have posted sound a touch more like fantasy rather than reality. Again I could be totally wrong. I have in my time known some people that would possibly react the way you say your roommates have… maybe.
Nobody buys NAV- it comes for free when you buy your computer. That said, you got less than what you paid for. So now you need do do two things to fix the issue:
1. Remove all traces of anything Norton from your computer.
2. Install one of the freebies. My personal favorite is the one from Microsoft.
Then run a full machine scan for mal ware before you do any surfing.
