I doubt it's a virus.  Filling up a hard-disk is counter productive to

Hi:

Well if the virus releases the space before infection, can be productive to
the propagation since it would reserve that space you won't be able to fill
with other data ;).

Generally is easy to detect a virus. Feed your computer with a couple of
fresh executables, and some will go out modified with high probability and
most times with the size increased. Warning there are slow viruses that
takes it's time to reproduce, and usually last years before somebody even
notices. However this is not very usual, generally viruses eat whaetever you
give them except some with bait detection. Most check baits for the size,
and some do more advanced thingies like analize the file for knows routines
in High level laguages or variations in the instructions. If interested I
have a lot of literature around and a huge 5000+ virus collection build over
the years. Some are still on schedule for reversing but if anyone is
interested just gime a call it would be great to save myself some time.

Waldo Alvarez
