                        The command-line options

F-PROT.EXE is usually run without any parameters and will then enter
interactive mode, but if the /HARD option is used, or a drive, file or
directory is specified, it will enter command-line mode.

Syntax for command-line mode:  F-PROT [drive, file or directory] [options]

The available command-line options are

/APPEND
Appends the report to an existing file (Only used with /REPORT).

/ARCHIVE
Scans inside .ZIP and .ARJ files.  Support for .LZH and .RAR archives, as
well as self-extracting archives may be added later.

/AUTO
May be specified with /DISINF, /DELETE or /RENAME so F-PROT will not
request permission before rremoving each virus.

/BEEP
Produces an annoying beep when a virus is found.  NOT recommended when
scanning a virus collection.

/COLLECT
Assumes what is being scanned is a virus collection, where viruses might be
found in "abnormal" locations.  In particular, selecting this option will
enable detection of file images of boot sector viruses.  This switch also 
provides the same features as the old /GURU option.  Note that using /COLLECT
will slow down the scan.

/DELETE
Deletes infected files.

/DISINF
Disinfects whenever possible.  It is possible to specify the following
combinations of switches:

    /DISINF /DELETE
        Disinfects when possible, otherwise deletes infected files.

    /DISINF /RENAME
        Disinfects when possible, otherwise attempts to rename infected COM/EXE 
        files to VOM/VXE.

    /DISINF /RENAME /DELETE
        Disinfects when possible, otherwise attempts to rename infected COM/EXE
        files to VOM/VXE, but if that fails the files are deleted.

/DUMB
Does a "dumb" scan of all files.  This option is practically never
necessary, and will normally just result in a significant slowdown of the
scanner.  The only cases where it might be needed are the following:

    If you are scanning a virus collection, where infected files have
    non-standard extensions, such as .VOM instead of .COM, they will not
    be scanned for viruses, unless this switch is specified.

    If you are cleaning up a virus infection you should use this
    switch.

/EXT
By default F-PROT will open every file and try to determine its type,
so it will for example scan Word files, even if they do not use a DOC/DOT
extension.  By using /EXT the scanning can be speeded up slightly as F-PROT
will then only scan files with "default" extensions.

/FREEZE
"Freezes" the program if a virus is found anywhere.

/HARD
Scans all files on all hard disks in the computer.

/HELP
Displays the list of command-line options.

/INTER
Forces the program to enter interactive mode, even when a path, directory
or file name is given on the command line.

/LIST
Lists all files that are scanned.

/LOADDEF
Load the DEF files into memory.

/NOBOOT
Does not scan boot sectors.

/NOBREAK
Disables ESC and ^C during scanning.

/NOFILE
Does not scan files.  Only useful if you cleaning up a boot sector infection
and do not want to spend unnecessary time scanning files.

/NOFLOPPY
For use on systems without floppy drives.

/NOHEUR
Version 3 has a smaller, more reliable set of heuristics than version 2,
but they are enabled by default, unlike version 2.  This option allows
you to turn the heuristics off.

/NOMEM
Does not scan memory for viruses.  Not recommended, unless you are
absolutely certain that no viruses are present in memory.

/NOSUB
Does not scan subdirectories.

/PACKED
Scans "inside" various types of compressed executables (PKLITE for
example), by emulating the execution of the decompressor.  As this option
can slow the scan down significantly, we only recommend using it when
scanning new software before installation.

/PAGE
Pauses after each page (command-line mode only).

/REMOVEALL
Removes all macros from all documents.  Useful if you encounter a new
macro virus, and you know that the document did not contain any macros
before it got infected.

/REMOVENEW
If a new variant of a macro virus is found in a document, all macros are
removed from that particular document.

/RENAME
Renames infected COM/EXE files to VOM/VXE.  If files with those
extensions already exist, .VVV  is used instead.  Infected document files
are not renamed, as that would be pointless - they would be equally
infectious afterwards.

/REPORT=file
Sends the output to a file, in addition to displaying it on the screen.

/SAFEREMOVE
Removes all macros from documents, if a known virus is found.

/SILENT
Does not generate any screen output (command-line mode only).

/VIRLIST
Produces a list of known viruses, as well as information on whether they
can be disinfected.

/VIRNO
Counts the known viruses and reports the total.

/WRAP
Wraps text so the report fits in 78 columns.


The program uses the following exit codes, which can be checked with the
ERRORLEVEL command from a BAT file.

    0 - Normal exit - nothing found
    1 - Abnormal termination - unrecoverable error.  This can mean any of
        the following:
            Internal error in the program.
            DOS version prior to 3.0 was used.
            ENGLISH.TX0, SIGN.DEF or MACRO.DEF corrupted or not present.
    2 - Selftest failed - program has been modified.
    3 - A Boot/File virus infection found.
    4 - Virus found in memory.
    5 - Program terminated with ^C or ESC.
    6 - A virus was removed.  This code is only meaningful if
        the program is used to scan just a single file.
    7 - Insufficient memory to run the program.
    8 - At least one suspicious file was found, but no infections.
