 Usage : DIF [Path+filename1] [Path+filename2]

 The computer viruses that attach themself at executable or other files are
 called LINK viruses. After the infection of a file this file is changed
 so that it is not anymore exactly the same file. With this utility it's
 easy to check if a program has changed or not by comparing the first file
 with another file that is (hopefully) not infected. If you want to check
 for example if the disk-validator on disk is infected by the very dangerous
 virus Return Of The Lamer Exterminator you can type :
 1> DIF dh0:l/disk-validator df0:l/disk-validator
 This utility will detect that there is a difference between the two disk-
 validators if one of them is infected. Be careful,however,if the disk-
 validator on the harddisk is also infected there won't be a difference.
 I advise you to copy a CLEAN disk-validator to another directory like
 S: and later on use the file in this directory to compare it with the
 disk-validator(s) in the L: directory.
