http 404

[Doug Adkins]

I contacted my DSL line provider because every time I go to
asearch engine I get a" http 404-file not found " response.
They informed me that my computer had been hijacked and
that they couldn't help me. Can anyone out there help me?
I do not have a clue what that means or how to fix it.
Thanks,
Doug Adkins

It prevents access to the most major search engines such as Google, Yahoo,
Lycos, MSN and AltaVista. To do this it replaces the following file:
