Norton is the pretense of security, at the expense of resources. If you like it, you should buy another gig of ram to support it. I personally prefer chewing broken glass to running norton, and leaving pins on the floor outside my wide open front door for security. BitDefender is pretty good if you want to spend money, alternately there are stacks of excellent antivirus software out there as the other people in this thread suggest.
sementech... sorry symantec will be paying sony for every installation they hoist on an unsuspecting customer, and I hope they are paid well for it, as they'll be burning in hell for what they've done. I'm very very tempted to bill sony for the time i've wasted uninstalling the crud these new machines come with. most of it is downright obnoxious.
