Boy, you ain't just whistlin' Dixie!  I took the time to upload all of
the patches and whatnot, I purged the spyware, I deleted things that
were hiding on my computer, and I did everything else Pshemekan
recommended.  

Now my computer purrs like a kitten!  Things work faster, too!  It
made such a difference.  Thanks, Pshemekan!

One more question, though.  I have heard that folks with a cable
connection ought to have a good firewall to prevent someone from
extracting information from the computer.  Can you explain why this is
not really necessary?

Grateful!Cindy
