Mathematica 8 + OS X + McAfee = trouble; help?

Under Mac OS X 10.6.8 (Snow Leopard) I've been having persistent 
troubles getting the Mathematica 8.0.4 front end to connect with the 
kernel when I start the program, and to start the PacletManager, too. 
Evidently, the problem is caused by JLink not starting or running properly.

After substantial direct help from Wolfram tech support, we've traced 
the problem to McAfee Security, specifically, Version 1.1.0 (1309), with 
its anti-malware version 9.1.0 (4478), engine version 5400.1158.

Has anybody else encountered this?

What happens is that with normal on-access scan enabled, the JLink 
problem occurs; with on-access scan disabled, the problem disappears.

I'd like to be able to keep McAfee Security and simply specify the 
needed file exclusions from on-access scan. We've tried to exclude the 
entire package (i.e., $InstallationDirectory) as well as 
/Library/Mathematica (i.e., $BaseDirectory), and even the entire 
$UserBaseDirectory. But that doesn't do the trick.

Perhaps the exclusions need to include specific files in those 
directories, or even some Java files/directories. The Mac in question 
has the usual Apple 64- and 32-bit Javas, version 1.6.0_29-b11-402.

Any suggestions?
