Just a small remark: when the load average goes up, OS X will create
those swapfiles and number them consecutively. When the load average
goes down again over an extended period of time, it will delete them
again. I have seen this behavior on my box: after doing some memory-
intensive stuff, I could see swapfiles0 through 3 in /var/vm. After a
while of normal use, swapfiles 2 and 3 were deleted again. So, to sum
up: the fact that you couldn't find the offending file doesn't mean
it wasn't there when Norton reported it.
This being said: I've stayed away from all Norton products since the
advent of OS X, and my computing exeprience has been a lot smoother.
Even on Mac OS 9, the latest atavars of Norton System Works were
extremely unstable and dangerous; with OS X, it was disastrous.
