In case anybody didn't know about it, there's a
remnant from some popular virus scanner that gives
you a growing file that eventually gets big enough
to matter.
c:WINDOWS/system32/drivers/fidbox.dat
It's harmless to delete (and will grow again over
a period of months) but you have to be in safe
mode.
A smaller one
c:WINDOWS/system32/drivers/fidbox.idx
can be deleted at the same time.
The feature stays there long after the virus
scanner has gone.
It's worthwhile to check if you have them.
