all of a sudden, after installing "avery" program, then deleting it because it inserted "ask" search feature, NOW I am missing the line at the top that has the WEB ADDRESS, BACK BUTTON, HOME BUTTON ETC. NONE OF THESE ARE THERE, HOW DO I GET THEM BACK?

I have Windows XP.

my home page is Google. this is coming up, but without the web address area and all the buttons at top such as back arrow, forward arrow, refresh, etc . all those things that are usually there are not there. I cannot type in a web address. I can only get to an address by typing it into the google search window in middle of the page, even if I know the web address because there is nowhere to type the web address! How do I get this important line back on the screen!! thanks !
