Seems like it's getting there. Those active progs don't mean much to me, I'm afraid, although at a guess there's nothing there that's ESSENTIAL for normal ops. If you can get it back to Explorer and Systray only, and then see if anything is not operating correctly, it should indicate what needs to be on the Start selection. The Nprotect is almost certainly Norton so possibly worth keeping that active if you are going on the net. (On a personal basis, Norton has caused me more problems than it has solved so it's gone to the big Recycle bin)
For the defrag, if you haven't done one before, it's probably best done in Safe Mode so you don't have problems with screensavers etc. cutting in and stopping the action.
