Yes I have had a cpouple of problems, bear with me. 1) I have a program called lockngo
my old external HD died and I had to install lockngo on my new 1tb portable drive. Norton would not let me do it saying it was dangerous. I disabled the antivirus auto protect, and the smart firewall, but it still would not let me install kockngo. Eventually because I was running out of time I uninstalled Norton, installed lockngo on my portable drive then used system restore to get back to square one. Not a good way to proceed!
2) After a full scan I clicked on "Settings" and it froze with this message " Symantic System Framework is not responding" I had a choice to wait or close program, I closed but had to reboot to reload Norton. I do not know if this was afault in Norton or my computer, but it has not occurred again. I like to think it was a glitch in my computer, as I like the program very much, and since I already run NIS 2011 I would upgrade to NIS 2012. It is neat and tidy, uses a minimal of resources and simply works quietly and efficiently in the background.
