           Central Point Anti-Virus for DOS Version 2.2
  
  This file contains information that is not in the manual or has 
  changed since the manual was printed. Please take a moment to read it.
  
  
  SIGNATURE UPDATES AND OTHER CENTRAL POINT PROGRAMS
  
  Signature updates improve the virus-detection capability of other 
  Central Point Software programs that have virus-detection features 
  (Central Point Backup, DiskFix, and Commute). However, the virus 
  signatures used by Central Point Anti-Virus Version 2.2 are not 
  compatible with these Central Point programs. Signatures using the
  previous format will still be available on CompuServe and 
  Central Point's BBS.
  
  
  INSTALL OPTIONS
  
  After you perform the initial installation, you can complete the 
  following procedures from the directory where Install is located 
  (by default, C:\CPAV) on your hard disk drive: 
      *       Creating an emergency disk 
      *       Changing Anti-Virus options 
      *       Creating a custom installation or installation set
  
  
  ADDITIONAL PK ZIP SUPPORT
  
  Central Point Anti-Virus Version 2.2 supports PK Zip versions 1.x 
  and 2.x.
  
  
  USING STACKER AND MAKING AN EMERGENCY DISK
  
  When you make an emergency disk, you might get a message that the
  process cannot be completed. If so, Install detected that you have 
  Stacker loaded and are swapping drives. When you make an emergency 
  disk under these circumstances, the boot area of the hard disk drive 
  is swapped. However, when you boot your computer from your emergency
  disk, you need one that boots without loading Stacker and swapping 
  drives. To create one, follow these steps:
  
  1.  Create a formatted, bootable floppy disk in drive A.
      Type
      FORMAT A: /S and press Enter
      
  2.  Copy BOOTSAFE.EXE to the floppy disk.
      Change to the C:\CPAV directory and type
      COPY BOOTSAFE.EXE  A:
      
  3.  Restart your computer and boot from the floppy disk in 
      drive A.
  
  4.  From drive A, type
      BOOTSAFE C: /M
      
  5.  Choose Yes to save an image of the partition table to the floppy 
      disk in drive A.
      
  6.  Write-protect the floppy disk, place a label on it, and store it 
      in a safe place.
      
      
  SCHEDULING ANTI-VIRUS SCANS
  
  If you manually install the scheduler TSR (CPSCHED.EXE), make sure you
  add the full path to the program (C:\CPAV\CPSCHED) and that you run it
  from the same directory as the SCHEDULE.EXE program. If you have 
  Install add CPSCHED to your AUTOEXEC.BAT file for you, this has 
  been done.
  
  
  PC Tools for DOS Users  
  
  To schedule Central Point Anti-Virus 2.x scans along with your other
  PC Tools events, delete the CPSCHED.EXE and SCHEDULE.EXE files from 
  the CPAV directory. Then start Scheduler from the PC Tools directory 
  and add the full path to Central Point Anti-Virus 2.2 in the Event 
  text box (C:\CPAV\CPAV.EXE). Edit your AUTOEXEC.BAT file and change 
  the CPSCHED line to include the full path to the PCTOOLS directory
  (C:\PCTOOLS\CPSCHED).
  
  
  PC Tools for Windows Users
  
  To schedule Central Point Anti-Virus 2.x events using Scheduler in 
  PC Tools for Windows, follow the instructions for importing a file 
  found in the Scheduler chapter of the PC Tools for Windows manual.
  
  
  SCANNING NETWORK SERVERS
  
  When scanning a network server from the command line (using /N or /P),
  you get no visual indicator when the program is mapping the directory
  structure and it may appear locked. Since network drives tend to be 
  large, they take longer to process.
  
  
  USING ISCPSTSR.EXE AND VSAFE/VWATCH Version 2.x 
  
  The ISCPSTSR.EXE program that Central Point Anti-Virus uses to check 
  the system for resident protection can now check to see if users are
  running a specific Version 2.x TSR. If you specify VSafe in the 
  command line, and users are running VSafe Version 1.4, ISCPSTSR 
  returns an error level indicating that VSafe is not running. It will
  only recognize VSafe and VWatch Version 2.x. 
  
  To specify that users accessing the network use VSafe or VWatch, use 
  the following format in the system LOGIN script:
  
  #ISCPSTSR VSAFE
      or
  #ISCPSTSR VWATCH
  
  If you want ISCPSTSR to check for earlier versions of VSafe or VWatch, 
  use the ISCPSTSR command without specifying VSAFE or VWATCH. For more 
  information on using ISCPSTSR.EXE, see the "Tips for Network
  Administrators" chapter in the Central Point Anti-Virus for DOS
  Version 2 manual.
  
  
  BOOTSAFE ERROR CODES
  
  The Error Codes table in the "Tips for Network Administrators" chapter
  is incorrect. The following table shows the correct list of BootSafe 
  error codes to use in a batch file:
  
  BootSafe Returns 
  this Error Code         When this Condition Exists
  ---------------         --------------------------
      0                   No problems found.
      2                   It is time to scan (works with /T option)
      3                   A virus is found, or the master boot record 
                          has changed.
      4                   There is no image file on the disk.
			  BootSafe has not created one.
  
  
  COMPATIBILITY NOTES
  
  
  Packard Bell Mouse Users
  
  The Packard Bell mouse driver version 4.0 is not fully compatible 
  with the Microsoft mouse driver (version 6.14 or later). Use the
  Microsoft mouse driver (often provided with Windows) with this mouse.
  
  
  Speedstar 24X Video Board Users
  
  The 24XMODE.COM file changes each time it is executed. To prevent 
  verification alerts each time the driver is run, add this file to 
  your Verification Exceptions list.
  
  
  PC-Kwick Users
  
  To uninstall the Central Point Anti-Virus files from your hard disk,
  disable PC-Kwick first. Otherwise, all files might not be removed.
  
  
  Novell DOS 7 Users
  
  The extended memory driver shipped with Novell DOS v7 is not fully
  compatible with VSafe. Make sure you are using DPMS v1.02. 
  Contact a certified Novell representative if you have questions. 
  You can also install VSafe using the /NX option to prevent the use
  of extended memory.
  
  Disk-Compression Software
  
  When scanning drives that have been compressed with the 
  disk-compression utility SuperStor from AddStor, turn off the 
  Anti-Stealth option. On such compressed volumes, files are
  compressed and decompressed dynamically, which results in their 
  checksums not matching. You may get unreliable verification errors.
  
  
  DOS 6 DoubleSpace Users
  
  To make a Central Point Anti-Virus emergency disk, you must first 
  create a bootable, formatted floppy disk, and then create a 
  CONFIG.SYS file on the emergency disk that contains the following
  statement:
  
  SHELL=A:\COMMAND.COM
  
  
  QEMM or 386MAX 
  
  Some problems have been detected when loading VSafe and using the 
  SQUEEZE option in QEMM or the FLEXFRAME option in 386MAX. For 
  best results, do not use either of these options if you are 
  loading VSafe.
  
  If Install detects that you are using QEMM, it adds the /L option
  to VSAfe or VWatch, which forces them to use conventional memory 
  instead of automatically loading into upper memory blocks (UMBs). 
  If you want to use UMBs after installing VSafe or VWatch, remove 
  the /L option before optimizing memory with QEMM.
  
  If you get the message "386MAX VxD error V1014: Disk Cache or other 
  file IO software using EMS memory" when using VSafe with 386MAX, load
  VSafe using the /NE option.
  
  
  VSafe and Other TSRs
  
  If you have VSafe loaded with the Resident Warning option (2) on, 
  you might receive an error when another memory-resident program 
  loads. If you choose Stop, the system might lock. Choose Continue 
  to complete the startup process, then edit your AUTOEXEC.BAT file 
  and turn off the Resident Warning option (2-).
  
  Generally, the only reason for not using the VSafe default options 
  is if you think your system might be infected with a virus. If this 
  is the case, boot your system from your write-protected emergency 
  disk. Follow the instructions in the manual for using the emergency 
  disk.
  
  
  VSafe and DESQview
  
  VSafe does not display a warning when you are running a DOS program 
  in graphics mode (such as DESQview); instead, an alarm sounds and 
  the action stops. Exit from the program and run Central Point 
  Anti-Virus to verify the integrity of files.
  
  
  DOS Shell Users
  
  If you are using the DOS Shell program in graphics mode when a 
  scheduled Anti-Virus scan begins, the screen fonts will not be 
  drawn correctly. When you return to the DOS Shell, choose 
  Repaint Screen from the View menu to redraw the display. To run 
  Central Point Anti-Virus from the DOS Shell without this problem, 
  run the DOS Shell in text mode. 
  
  
  Banyan Vines Network Users
  
  If you want to use VSafe on Banyan Vines network workstations, 
  load VSafe after the network drivers.
  
  
  KEYB.COM Users
  
  If you want to use both VSafe and KEYB.COM, load VSafe after loading 
  KEYB.COM.
