You need a single anti-virus. Use either Avast or AVG, not both.

You need a browser. Both Firefox (from Mozilla) and Internet Explorer are browsers, so you can just pick one.

If you don’t use an instant messanger, I wouldn’t have it turn on when you boot up. You can turn it off. That is likely the “Yahoo” your friend added for you.

Thank you, I'm not sure at this point, what a browser is, Fire fox sounds groovy!
