一開IE唔係我set ge首頁問題

次次開IE都係咁:個website由http://go.microsoft.com/fwlink/?LinkId=74005好快轉左做http://runonce.msn.com/runonce2.aspx 網頁內容:
Server Error in '/' Application.
--------------------------------------------------------------------------------

The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /runonce2.aspx

另外有時唔知點唔係去呢個畫面而去左http://www.msn.com/
但係我set左首頁做http://hk.yahoo.com/同開分頁都冇事
