SCAN - The program
SCAN (also known as VIRUSCAN) is a virus detection and
identification program for the IBM PC and compatibles,
manufactured by McAfee Associates, U.S.A.
SCAN searches your computer for known viruses in memory,
boot sector, partition table and selected files on your
diskettes and hard disks. SCAN detects known viruses by
comparing your files to specific signatures strings
stored in the SCAN executable file.
SCAN can optionally protect your system against new,
unknown viruses by appending validation codes to .COM
and .EXE files and later check these values against any
changes, warning you of any changes taken place.

'CLEAN' - The program
CLEAN (also known as CLEAN-UP) is a virus disinfection
program for the IBM PC and compatibles, manufactured by
McAfee Associates, U.S.A.
CLEAN searches through the boot sector, partition table,
or files of your computer and removes a specified virus.
Normally CLEAN is able to repair the infected area of
your computer and restore it to the preinfected status.
However, some specific viruses is working by physically
overwriting the file infected, thus making it impossible
to restore the file. In this case SCAN asks you if it is
OK to overwrite and delete the file. You are advised to
do this to stop further infections from the virus.

Go to Help index
Scan - Check validation codes
If you set this option to ON, Scan will check the
files for previously inserted validation codes.
If the validation codes don't match, Scan will report
that the files has been modified and that a viral
infection might have occurred.
Certain programs writes their setup to the executable
program file, thus making Scan report a false virus
infection.
Using this option adds 25% to the scanning time.
Go to Help index
Scan - Scan overlays
When Scan is scanning program files for viruses, it
looks for the normal program extensions, .EXE, .COM
end .SYS. Some programs also store executable code in
overlay files. If you set this option to ON, Scan will
search files with other extensions.
To add the names of the extension change them in the
submenu Scan - Overlay names. Up to three different
extensions can be added.
Go to Help index
Scan - Delete infected files
This option tells Scan to prompt the user to
overwrite and delete infected files when found.
After deleting the file cannot be recovered.
This option should only be used if Clean is not
available, since Clean usually is able to safely
remove the virus and recover the infected file.
Boot sector and partition table infectors cannot
be removed by this option, use Clean.
Go to Help index
Scan - Scan memory for all viruses
This option tells Scan to search memory for all known
viruses that can be memory resident.
In normal use, Scan only checks memory for certain
viruses that otherwise would infect all files during
the scan, or otherwise causes damage during the Scan.
Go to Help index
Scan - Scan inside LZEXE files
This option tells Scan to look inside files compressed
with the LZEXE file compression program.
If this option is off, Scan will still check these
files for external infections.
The only way a virus can be contained inside a LZEXE
is if the program file was infected prior to packing
with the LZEXE file compression program.
Go to Help index
Scan - Scan inside PKLite files
This option tells Scan to look inside files compressed
with the PKLite file compression program.
If this option is off, Scan will still check these
files for external infections.
The only way a virus can be contained inside a PKLite
compressed file is if the program file was infected

Scan - Autorun Clean
This option determines whether Clean automatically
should be run after Scan when a virus has been found.
By setting this option to ON you are saved from
manually setting the options of Clean to clean the
infected files as found by Scan.
If you set this option to OFF, you run the risk of
miss an option, effectively making the cleaning of the
system incomplete, and leaving some files infected.
Go to Help index
Use external scanfile
This option is used to search for viruses from an external
textfile containing user-defined search strings. This file
should be called VIRUSHEL.DAT and be placed in the current
directory.
This option is intended for use as an emergency exit, this
file can for example be distributed by your dealer to take
care of a fast spreading virus until a new version of SCAN
has been released.
Note: If you create this file yourself, it is recommended
that it is not used together with the 'Delete infected
files' option of Scan.
Go to Help index
Scan DOS 4 boot sector
This option should be used to scan hard disks partitioned
under DOS 4.0 or above that has been damaged by a boot
sector or partition table infecting virus.
Hard disks infected this way gives the 'invalid media'
error message when accessed, this means that you should
only use this option if you get this message when you
try to access the drive.

Skip filename display
Normally when SCAN or NETSCAN is scanning your disk(s)
for virus infections, it shows the name of the file
that is currently scanned. This may prolong the actual
scanning process to much if there are many files to
scan.
Turn this option ON to show the files as they are
scanned, and turn it OFF to stop the files from being
displayed as they are scanned.
Go to Help index
Beep when virus found
With this option you can select if SCAN and NETSCAN
should make a beep for every virus found while the
actual scanning is in progress. ViruShell always gives
a warning sound after the scanning is finished in case
a virus was found.
Turn this option OFF if you know that a lot of files
on your system is infected and want to speed up the
scanning, leave it ON in all other cases.
Go to Help index
Clean - Clean all files
By turning this switch ON, Clean is forced to clean
all files, including data and overlay files, in the
selected path.
Use this if an overlay-infecting virus is found by
Scan.
This option should be used as a safety instead of
using the 'Scan overlays' option, since overlays
might have an extension that don't match on of the
three extension that can be used with that option.
Go to Help index
Clean - Clean overlays
By turning this option on, Clean will try to clean
overlay files as well as the normal program files.
This option uses the extensions added in the Clean -
