I'm running SP1 and i'm not worried about. I have an up-to-date Firewall, Antivirus, Spyware blocker. Plus i don't use Internet Explorer or Outlook Express. So i guess i'm free of 95% of all security flaws. :-D
Ugg It seems after further research my MOBO (DFI NF2 Ultra Infinity) and its drivers don't like to play with SP2. Looks like i'm going back to 2000 Pro until they get the kinks ironed out...
