Note that this doesn't have to be the work of a virus. It is perfectly
possible in GEMDOS to have two files with the same pathname (whether
this is desirable or documented is another question: you get lots of
problems deleting or accessing one or the other).
I did something like:
0) Start first program
1) first program opens the file readonly
2) Pexec second program
3) second program opens the same file write-only
4) writes into the file
5) closes it and exits
6) first program closes file and exits
and then I had two copies of the file. The program in question was in
fact a 'more' utility which can fork a 'vi'; this option I no longer
use because of the duplicate files problem.
Perhaps you have an analoguous problem; for instance if your shell for some
reason keeps files opened (e.g. shell scripts, files to which redirection
is done) you will encounter the same problem.
I suggest you check all your tools and programs for weird behaviour by
keeping constant track of the contents of your directories for a while.
Hope this has put you at ease somewhat - it could still be a virus 8-).
Happy virus-hunting!
Leo.
