Hmmm..."log off" to me, means choosing that from Start, and having it basically said "bye-bye" and then no one can use my PC unless they sign in and give a password. I only have me as a user so that's not a problem. I never used to use it, but my Rog told me it's a good way to make sure people cannot use my computer, through wireless connections, without my permission. NO, I doubt if there are folks trolling the neighbourhood looking for a hot spot, but I like the idea of added security anyway.:-)

SUPERintispyware seems to do a good job and is easy to use. It was recommended by a tech guy at Dell when he helped me about two months ago.

I don't understand the registry things and I suspect that I get into trouble by not knowing, so will go read up on it and see if I can understand it. Thanks, John.
