Consider for example the entire class of boot sector viruses, which used to be quite common. None of those could work without someone carelessly booting from an infected floppy. Similarly in this case, the virus can't propagate without someone (preferably root) executing an infected file. Paul. -- Paul Howarth <paul@xxxxxxxxxxxx>
