my computer is not rebooting, as the sausser worm will cause. Also, ive played BD offline, turning off the cable modem. And it still randomly breaks norton antivirus if its active and installed. It makes no difference if norton autoprotect is enabled or not. Plus i have zone alarm pro on my box, keeping a lid on suspicious activity that would try to go out from my computer, as well spyware cleaner. I noted if you shut down ccapp in the task manager, which is part of norton, the corruption will never happen, as norton is not active. You can see it by the icon for autoprotect vanishing from the taskbar.
