IE6 not allowing me to use search engines

I have tried everything. Reinstalling IE6 and virus checks, and scand disks and everything. But no matter what I do I cannot seem to get the internet to allow me to use search engines. First I type msn.com then it loads but as soon as i type something into the search area and press enter a 404 page error pops up[ saying that this page annot be displayed. Please I've had this problem for many months and really need it fixed. Also its not only msn, its google,yahoo etc. I have XP home edition and have had it working for awhile. I know that its not the connection as I can use my brothers computer with the internet.
