- 1.0 Overview
-
- VPCShell is a user friendly interface for VPCSCAN or VIRx, featuring pull
- down menus. VPCShell allows you to easily select options for either scanner
- and then shells out to the selected scanner to perform the scan. The menus
- can be accessed via mouse clicks, keyboard cursor keys, and highlighted 'hot
- keys'. Individual selections in the pull-downs can be selected or toggled by
- pressing the <SPACE> or <ENTER> key. Any setting you change will stay in
- effect for all scans until you exit VPCShell. Settings can be saved for
- future runs via the save configuration setting selection under Options. The
- main selections for VPCShell appear across the top of the screen with pull
- down selections for each. The bottom line of the screen is a descriptive
- text line describing the currently highlighted menu item. Below the program
- title box is the currently selected inoculate and checksum files to be used.
- VPCShell can be run from DOS or from within Windows. Some options are not
- available if using the VIRx freeware scanner and will be darkened, and cannot
- be selected.
-
- This document will not cover in detail the various scanner switches. Owners
- of the full Virex for the PC package should reference their users guide,
- while VIRx users should reference the readme files that are distributed with
- it.
-
- VPCShell can be used and distributed freely as long as it is distributed
- unaltered, with all its associated files.
-
- 1.1 Installation:
- The recommended method to install VPCShell is to copy all of its files to a
- diskette or install directory. If you choose to install from a directory
- rather than from a diskette, the directory should not be the same directory
- that you intend to install to. If you are a Windows 3.x user, the install
- program can install an icon from which the shell can be run from within
- Windows. Before installing VPCShell you should already have installed
- VPCSCAN or VIRx, and Windows, if installing the icon.
-
- To install, simply run the INSTALL program and you will be presented with two
- options. You may choose to install for DOS only or you may choose to install
- for DOS and Windows. After making your selection you will be prompted for
- the location where Virex has been installed. You should enter the directory
- where VPCSCAN.EXE or VIRX.EXE is located on your hard drive. If you chose to
- install for Windows also, you will be prompted for the directory where
- Windows is located. Enter the location of Windows on your hard drive and
- installation will be automatic from there. Once installation is complete,
- change to the directory you chose to install to and run VPCSHELL. If you
- chose to install for Windows you will now have a VPCShell icon in a Virex for
- the PC group. Simply double click on the icon to launch VPCShell from
- Windows.
-
- 1.2 System Requirements for VPCShell:
-
- VPCShell must be installed to the same directory where VPCSCAN.EXE or
- VIRX.EXE is located.
-
- VPCShell requires about 120K of memory to run. VPCSCAN or VIRx require about
- 350K of memory. This brings the total memory requirement to around 470K.
-
-
-
- The files for VPCShell are:
-
- INSTALL.EXE Install program for VPCShell.
- VPCSHELL.EXE The main VPCShell program.
- VLIST.EXE Displays the viruses detected by VPCSCAN or VIRx.
- VPCSHELL.CFG Created by VPCShell if you save configuration changes
- READ_ME.TXT This text file.
- VIREX.GRP Windows Group File.
- VIREX.PIF Windows PIF file.
- VIREX.ICO Windows icon.

-
- 2.0 Scan:
-
- This is where you choose what will be scanned by the scanner. When your
- selection is made, VPCShell will launch the selected scanner with the
- selected options to scan.
-
- 2.1 Drives:
- This allows you to choose entire drives to be scanned. After choosing this
- you will be presented with a drive selection box from which you may choose
- single or multiple drives to be scanned. You may tag drives to be scanned by
- single clicking on a drive letter or by highlighting a drive letter and
- pressing the <SPACE BAR>. After tagging the drives you want to be scanned,
- press <ENTER> or double click on a drive letter to scan. Single drives may
- be chosen simply by highlighting the drive letter and pressing <ENTER> or
- double clicking on the drive letter to scan.
-
- 2.2 Directory:
- This allows you to choose a directory of files to be scanned. First you will
- be presented with a drive selection box to choose the drive where the
- directory to be scanned is located, then a directory tree of the selected
- drive will appear for you to choose a directory to be scanned. You can
- choose a directory by using the arrow keys to highlight the desired directory
- and pressing <ENTER> or by single clicking on the desired directory.
-
-
- 2.3 File:
- This allows you to choose a single file to be scanned. First you will be
- presented with a drive selection box to choose the drive where the file to be
- scanned is located, then a directory tree of the selected drive will appear
- for you to choose the directory where the file to be scanned is located.
- Finally, you will see a selection box with all the files in the selected
- directory. If there are more files than will fit on the screen, you can
- scroll down to see the rest of the files. You can choose a file by using the
- arrow keys to highlight the desired file and pressing <ENTER> or by single
- clicking on the desired file.
-
- 3.0 Inoculate Options (VPCSCAN only):
-
- 3.1 Use to Repair (VPCSCAN only):
- If NO: the only time that program files will be repaired with the inoculate
- file information is if a program is infected with a known virus and VPCSCAN
- does not have a disinfector for it. VPCSCAN will not be directed to use the
- inoculate file configured in VPCShell, rather it will use the default
- inoculate file pointed to internally by VPCSCAN.
-
- If YES: program files will be repaired with the inoculate file information if
- a program is infected with a known virus and VPCSCAN does not have a
- disinfector for it or if it is infected by an unknown virus. VPCSCAN will be
- directed to use the inoculate file configured in VPCShell.
-
- 3.2 Create/Update (VPCSCAN only):
- If NO: no creation or update of the selected inoculate file will take place.
-
- If YES: the selected inoculate file will be created if it does not exist.
- All files scanned will be added to the inoculate file. If the selected
- inoculate file does exist, then file information already contained in the
- inoculate file will be verified. If a change in an existing program file is
- detected VPCSCAN will offer to update the inoculate file with the new
- information or to repair the program from the inoculation information on
- file. All programs that are not already contained in the inoculation file
- will be added. This is the best way to repair files infected with an unknown
- virus or from a virus VPCSCAN does not have a disinfector for. Also, this
- option should be used on a regular basis to keep the inoculation file up to
- date. Remember, only files that have been inoculated BEFORE infection can be
- repaired in this maner.
-
- 3.3 Change File Name (VPCSCAN only):
- This will allow you to change the selected inoculate file. This might be
- used to create different inoculate files for different hard drives. This
- would only be necessary if the total number of file to be inoculated was over
- 3000. This is the limit built into VPCSCAN and it is very high and would not
- be easily reached.
-
- 4.0 Options:
-
- 4.1 Extended Memory Scan:
- If NO: only 640K of DOS memory will be scanned. 99% of all viruses will be
- caught with this scan.
-
- If YES: the entire 1st megabyte of memory will be scanned. While slightly
- more secure, it is usually unnecessary.
-
-
- 4.2 Single Floppy Scan:
- If NO: floppy drive scans will auto request the next floppy to scan. This
- assumes you will have several floppies to scan and speeds the process of
- scanning multiple diskettes.
-
- If YES: floppy drive scans will not request the next floppy to scan and will
- return to VPCShell after scanning a single diskette.
-
- 4.3 Scan Subdirectorys:
- If YES: all directories under the selected directory will be scanned.
-
- If NO: only one directory, the selected directory, will be scanned.
-
- 4.4 Long Scan:
- If NO: the selected scanner will use its smart, fast scanning method to
- search for viruses in the selected files. 99% of all known viruses will be
- caught with this method.
-
- If YES: the selected scanner will scan the selected files byte for byte
- throughout the entire file. While this is slightly more secure, the scanning
- process will be much slower.
-
- 4.5 Scan All Files:
- If NO: the selected scanner will only scan files with normal executable
- extensions for viruses.
-
- If YES: the selected scanner will scan all files regardless of their
- extensions. While this is normally not necessary it would catch a virus in a
- file that has not been properly named. While this is slightly more secure,
- the scanning process will be much slower.
-
- 4.6 Disable Memory Scan:
- If NO: memory will be scanned for viruses each time a scan is invoked.
-
- If YES: memory will not be scanned for viruses each time a scan is invoked.
- While this slightly reduces scan times and is useful while doing several
- scans in a row, we do not recommend this setting. Some viruses can only be
- found in memory if they are already in memory when the scan is started.
-
- 4.7 Verify Checksums (VPCSCAN only):
- If NO: checksums in the selected checksum file will not be verified.
-
- If YES: VPCSCAN will verify files already contained in the selected checksum
- file for checksum changes. This is useful to test previously checksumed
- files for changes, possibly due to unknown viruses. Files that are not
- already checksumed in the selected checksum file will NOT be scanned in any
- way.
-
- 4.8 Create a Checksum FILE (VPCSCAN only):
- If NO: a checksum file will not be created.
-
- If YES: the selected checksum file will be created and all files that are
- scanned will have their checksum written to it.
-
-
- 4.9 Change Checksum File Name (VPCSCAN only):
- This will allow you to change the selected checksum file. This might be used
- to create different checksum files for different hard drives or sets of
- files.
-
- 4.10 Display Virus List:
- The selected scanner will generate a listing of the viruses it detects and
- disinfects. This listing will be put into a file VIRUS.LST and then VLIST
- will be launched to display the listing. If you are running VPCShell from a
- write protected floppy, a new VIRUS.LST file will not be created, but if one
- already exists, it will be displayed. You may view the listing by scrolling
- with the cursor keys or use the mouse. Press <ESC> to exit the listing and
- return to VPCShell.
- Once a VIRUS.LST file has been created, VLIST can be run directly from DOS to
- display the virus listing.
-
- 4.11 Selected Scanner:
- If VPCSCAN: all options are enabled and VPCShell will use VPCSCAN for all
- scanning operations.
-
- If VIRx: the inoculate and checksum verify options are disabled. All other
- options are enabled. VIRx does not have any disinfection capabilities or
- checksum verification features.
-
- 4.12 Menu Shadows:
- If YES: all VPCShell menus will have shadows.
-
- If NO: menu shadows will not be displayed
-
- 4.13 Save Configuration Settings:
- This will save all selected options to VPCSHELL.CFG. If VPCSHELL.CFG exists
- when VPCShell is run, then options will be read from that file.
