Unfortunately, McAfee is one of the worst offenders in my experience
[1]. I seriously doubt you can disable it completely from user space,
given its habits of interposing on device drivers and burrowing into
other kernel bits [2].
[1] IMO it's a cure that's worse than the disease, but that's a rant for
a different thread.
[2] McAfee actually sued MS for "anticompetitive" behavior a while back,
after the latter closed a bunch of security loopholes in the kernel that
virus-writers love but McAfee also depended on (including the interrupt
dispatch table IIRC).
