Not really. Grif writes about UNHIDE too.
It appears you haven't cleaned off that nasty yet but I wonder if you took Grif's advice. You didn't tell.
Grif writes about UNHIDE.EXE at http://forums.cnet.com/7726-6122_102-5239386.html and this applies to what he writes there and files.
MY CONCERN HERE is that you appear to have no backup copies. That is, we only lose what we don't backup.
Are your files worth having a backup copy?
