                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.

There is a known problem with INSTALL when installing from floppies.
For this beta, please install like this:

c:\>A:INSTALL

and not like this:

a:\>INSTALL


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 Software'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


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 drive designators. 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 2.2 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 2.2 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.



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.


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.
