DELETED Ridiculous amount of stuff that probably should have been in
an attachment.

I am not familiar with the home version of McAfee VirusScan, but I do
run VirusScan Enterprise 8.0i, patch 11 at work.

Buffer Overflow Protection is disabled by default at the ePolicy
Orchestrator (management server) level because it broke a large number
of applications.

I would see if you can just disable that feature.

Also, if McAfee is the definitive problem, turn on all the logging for
McAfee and see if they tell you what they are blocking.

The home version of the product may have a lot more of their firewall
built in to it for all I know.

All this version does is simple port blocking and a little bit of
worm-like behavior blocking (which you may also want to check out if
you can).

My two guesses would be Buffer Overflow Protection and Access
Protection (that is what they are called in my version).
