HTTP 404 file not found

[Holly]

I did all the updates from Microsoft, ran the ad aware,
sybot and I have Norton anti virus and firewall running.
My problem is this: When at the Yahoo and MSN home pages
and type in a subjet to do a search it brings up the HTTP
404 error but if I go to Comcast.net and do a search from
that home page it will direct me to a list of sites. Why
are Yahoo and MSN not directing me to a list of sites?
Please help.
Holly

Thank you, it worked.
I have Norton running and for some reason it didn't
detect that QHost. Thanks a million.
