vista + norton 360 = total crap. i lasted 2 days. in those 2 days i had to reboot 7 times, because my windows validation kept getting unvalidated. 360 was shutting down my validation service. I couldn't disconnect my internet while it was running either. a real shame because i liked the toolset norton provides for keeping your computer in shape. i miss my systemworks though, it was loads better than this 360 crap. I use the AVGfree now though.
