My NIS (2004) just did a live update. It required a restart and further update. When the computer restarted I started receiving intrusion alerts. 1 about every 2 seconds for about 2 minutes. Quite annoying.

Restarting the computer didn't help. Tried 3 times no success.

I shut down again and turned off power to the modem for about 5 minutes. I restarted modem let the pretty little green lights come on and then retarted computer. Problem fixed. No more intrusion alerts.

That was my last resort before following the fixes for LW.

Thought I would share this information incase someonelse was having similar problems.
