System Safety Monitor

I think I may have a problem with windows. A couple of weeks ago NOD had an update that really screwed things up. I had to remove NOD and download an earlier version. Ever since I have had some strang things happening. I have 2 programs that don't want to respond when you try to shut down. Then like I had told you, a couple of times the screen saver wouldn't come on because SSM stopped the defrag.when it wasn't supposed to be defraging. Toninght I restarted Windows in the last good config. Hope that will help.
