Privacy

[Marilyn]

Earlier postings have helped me get rid of some malicious
invaders by using Adaware and Spybot. I still have some
unwanted things on my computer (like an internet toolbar
called cklyiewnkjx, although it no longer opens
automatically). But I have never changed my Privacy
settings which are probably at the default Medium Level.
Should I change them to avoid unwanted invaders to my
computer in the future, and, if so, how? Thank you.
