How do I set Y!A as my homepage?

I set the homepage in my IE, but again and again some other blog is being fixed as my homepage automatically.?

• I set the homepage by tools menu.. but when i click apply and ok, it again changes back .

• Answer:

  try setting the page as about blank and then apply the settings ...im doubtful about the virus thing but.....still download avast home edition from www.avast.com..................i dnt trust avg...i've used it and avast gives more better results...even better than norton or mc afee
