I am running XP professional, 32-bit. I recently renewed my subscription to Norton Internet Security and also bought Norton Utilities 15. Since I installed NU15, my computer will no longer reboot, only shutdown. I press restart, it does a soft shutdown. I have done "shutdown -r" from the command line and the C prompt. It just shuts down. I have to manually restart it,. Every source I checked for this problem said to look at the last software installation. That would be Norton Utilities 15.
