Dmitriy, what I was trying to point out is that normal operation of a Norton
AntiVirus scan should not be a bottle neck; if 7,714 files contining 182
Mbytes of data require only 1 minute 57 seconds with a Celeron 600, then you
should consider looking for some other bottleneck; page file thrashing, for
example that could be analyzed with 'Task Manager'.

What exactly is the task that requires 5 X the time with NAV as without NAV?
Your CPU should outperform the Celeron 600 mobile by about 3 times (if your
Pentium 4 is a Northwood.) If you are just transfering from one drive to
another within the same system, then 200 Mbytes of data in 7000 files would
take ~ 10 seconds without accounting for file overhead. If that is the
case, then 40 seconds CPU time used for scanning would increase the task
time by five. But that can't be the case, so the bottleneck is elsewhere.
