Most virus detecting programs work by intercepting writes to the hard disk and by checksumming programs before running them. A small change in a virus is not going to make it invisible to this type of checking. Jim Winer ..!lzfme!jwi I believe in absolute freedom of the press. I believe that freedom of the press is the only protection we have from the abuses of power of the church, from the abuses of power of the state, from the abuses of power of the corporate body, and from the abuses of power of the press itself.
