As you requested, I did a search for "Win32:CIH-G" and it only pulled up this thread. Also, before posting this thread, I did a search for war-ftpd to make sure I wasn't making a duplicate post.
I checked my catalog, and I have a copy of this on CD from 1998 that shows the same size to the byte, it will be a few days before I can get to this CD, (its at another location), but I will run an md5 check to see if they are the same. I don't recall ever getting hit by a virus while the ftp server was running though, and it has been about a year since I have run it. Avast! only recently flagged this, and it is the only file on my system to get flagged.
Also just ran a copy of it in VMware, seems to function normally.
I'll get a copy of this to Avast! tomorrow, I am curious to see what their virus lab has to say about it.
Thanks!
