(XP) 1)Should I Shut Down or can I always Hibernate? 2)How can I make a file undeletable? Meaning whenever someone tries to delete it the system says "Access Denied" 3)Whenever I want to run Firefox my computer says, "Firefox already running..." but that is not true! I checked all the running processes and DLL's firefox cannot be found. What is going on? And yes I tried in Safe Mode.
