I use MSN and last night a hacker hacked Bill Gates or something like that and I have an XP computer and that is the kind that got hacked (I think...I only heard this from my parents) and I the computer wouldn't do anything, then a screen appeared and said "complete system shutdown" and that scared me so much! I didn't know what I'd do without PT, lol, but my dad rebooted it and voila.
So...just warning you, our computer is a bit iffy now, so if I'm not on for a while, you know why.
