tis all good.
Well I've got numerous free copies of norton sitting around and I don't like it because it takes up too much resources... I use a nifty little program called AntiVir.. I've only had to buy it once and I haven't had to put anymore money into it

free virus updates. It requires little resources as well

also while I'm on that I would advise admuncher for blocking pop-ups and chewing ads

AntiVir can be obtained here :
http://www.free-av.com/(I think it's fully free now)

AdMuncher can be gotten here :
http://www.admuncher.com/(I'm having probs getting to that site right now but it worked this morning and I got the latest version so hmmm....)
have fun

EDIT: fixed some typos
