Just a note about defragging. Unless you are adding and deleting tons of files there is no need to defrag your drive 2 times a week. You are only really wasting your time and at two times a week brings no value. As far as using Zone Alarm and Poser or any other program ...do not turn it off unless you have to or you are disconnected from the internet via a cable modem. Zone Alarm only takes up about 8 megs of memory. I never shut off my Zone Alarm unless I'm physically disconnected from the internet.
