Norton Interent Security which I have had little problems witrh in the past recently screwed me over. It doesnt boot at start up and wont let me start the auto protect as it says i am not a supervisor but I didnt install accounts. Thus I can't uninstall as i dont have permission also i cannot reinstall as i have permission. I'm stuck without a firewall and also no anti virus. Any ideas? Also is there any better firewalls?
