Yahoo web page keeps coming up with porno picturs from a German 'Dialer' and I cant get ri

I have a porno 'Dialer' invasion on the Yahoo web page everytime I open it. I have used all my programs to try to clear it, i.e. Spyware, Adware,Virus remover, Windows firewall. But it keeps over-riding an advert on the left hand side of the screen then flashes to full screen then imbeds it program into my computer which I keep deleting from everywhere I can.

What can I do to get rid of this 'dialer' and prevent any others.

Thanks for help.
