Bob, you've put forward a significantly detailed description of the issue, and it's obvious that this 'gremlin' is completely unexpected.

There's nothing unusual with the A/virus software or something quite external that could get in the way?

Is the system on a network that could be causing unexpected downloads (/ uploads)?

I guess you'd already be well on top of those things anyway.
