This is getting to be extremely maddening. Nearly each time I leave my computer inactive for a sometime to run down to the corner store, for instance, Norton steps in and start performing 'background tasks'. This would be excellent and fine, apart from that while I return, I find out that all of my programs freeze up and I finish up having to do a hard reboot. It has gotten to the point that if I observe the small window in the lower right corner stating that it is performing background tasks; my heart goes under as I know that I have another collide on my hands. I observe that others have had same troubles in the earlier period. Is there a method or any technique to medicine this?
