I assume this means Norton Anti Virus? I'd recommend that you stay away from Norton. We had it on our computers for many years, and each year it got more and more bloated. It is a system hog and get's quite annoying, especially with that ugly 'Norton Brick' sitting in your Taskbar. Peer-to-Peer is fine if you know what your doing, don't download a full movie if it's 30mb... If in doubt, scan before you open and use common sense and you'll be fine. Banking Sites!? That is one of the major reasons you WOULD HAVE AN ANTIVIRUS PACKAGE. Seriously, you just open yourself up to giving away your money and credit card details if you don't have Anti Virus and you are using Banking Sites. You should NEVER not have a firewall/antivirus installed. The free ones, like AVG, do fine jobs and you should never be unsecured on the 'Net.
