Yesterday, May 25, 2015, I replaced Norton Internet Security with Norton Security at the end of the former's subscription. The installation seemed to go without incident.
The computer has become all but useless. The disk is running continuously. It takes 10s of seconds to respond to a mouse click.
The computer is a HP running Microsoft Windows 7.
The Norton Security was a package for 5 devices. I am also have a different problem with the installation on a Windows 8.1 machine the description of which I posted in another problem statement on this forum.
Any thoughts on what is going on?
Thanks.
