Thanks so much for your dedicated and clear help. I have learned quite a bit.
I will follow up with the links you suggested.
I am still debating Norton vs. AVG especially since AVG is free and I have found the free programs to run quite a bit better.
I will return in a couple of days to close this out if everything is ok.
The Leopard Tool Bar item, I noticed, is in Internet Explorer which my husband occassionally uses so I am still not sure whether I should fix/delete it or not.
Many thanks again. Karen
