The problem that exists is this. An application is generally requesting
(using) a kernel API in some way-shape-or-from. In other words the
application is not looking directly at the file directly on the disk. So,
if a rootkit is installed, and you are running a security app like Tripwire
on the same infected machine, then it really is useless (your asking the
rootkit if the system is infected). That is why the other posted said
"...booting from known-good cd".
