NIS Crashes PC While Performing Background Tasks

I have followed ALL previous suggestions including uninstalling and reinstalling NIS. Two days ago a NORTON Tech took over my PC remotelly, he performed many different adjustments BUT the problem is still there.

 

PC runs nice, fast, easy and smooth UNTIL Norton starts running its ridiculous backgrouns tasks and it is over. Nothing works, everything freezes, I have to manually turn the PC off and on again.

 

There are no conflicts with any other programs, this is a brand new i7 top notch computer but NORTON makes it run like it was a Windows 95 Intel -100 age of stone PC.

 

This is VERY frustrating!!!!

 

Please, someone out there help!!!!!
