Please help. Ever since installing the new Norton Security my computer freezes, mouse and keyboard totally inactive, after letting it stand for max 3 to 4 minutes like popping off to make coffee. Have to power off and then start up again . Unable to shutdown. Please help - spent ages online last night to Norton and remotely connected but problem still on-going. Have tried unplugging the computer and waiting half an hour and switching on. Have unplugged mouse and keyboard and plugged in....should I uninstall? HELP !!!! On windows 7 home edition - What can I do?
