Sent a false positive request to McAfee this morning, just got to wait to hear from them.
Heard back from Hex support, from the information they supplied and with some extra virus checking, Virus Total supplied by Ruan at Hex, I am almost positive it was a bum steer.
I took the plunge and created an exception in McAfee, scanned the hard drive and then successfully started the 911 program.
All is now working well and just waiting to hear from McAfee, I will update when I do.
