Problem with toolbar

[lovemydogs]

Hi, as you can see I'm new to the forum, my dh bought me a new laptop for Christmas which of course has Windows 7. I am having difficulty with the toolbar, I downloaded Yahoo toolbar which I like it has my many favourites etc. I download it and ran it my problem is it appears for a while then it disappears and like now all I have on the top bar is 'favourites' which hasn't got my many favourites in it, two pages which say Internet explorer cannot display the page, Yahoo! UK & Ireland 2 and 3 then multiply, Packard Bell and Web slice gallery. I do only have one page open though.

I will go off this forum onto another site and the toolbar will appear again then disappear, any suggestions gratefully received :dontknow:

regards
