Everytime I try my home page Yahoo it goes to Yahoo Singapore instead.?

I have Yahoo set as my home page, but everytime I try to go there it goes to Yahoo Singapore instead. I went to Yahoo Singapore a few days ago to read a story and that is when it started doing it. I have checked my home page designation and it says only Yahoo and I re-entered it to make sure but it still does it. I have also ran a scan through Super Antispy Ware and it still does it. Any suggestions on what I should do next? I guess I can live with it this way but it is annoying and an extra step to go to the right page.
