How can I hide google´s tool bar which has appeared along with the other tool bars at the top of my screen? I looked around under "settings" on the far right of the bar but found no "hide" option.

View > Toolbars, should do the trick.
Assuming of course you mean in IE.
If not please tell us EXACTLY where this toolbar is located.

The more information you give the better we can assist your issue.

Just uninstall it in Add/Remove Programs if you don't use it.
Otherwise you can right-click on any part of your toolbar and should be able to uncheck it. What browser are you using?

Thank you both. I don´t want to uninstalled it as I like having the pop-up blocker but there are no other features on it that I need and I´d rather have a little more screen space. It is now hidden.
