Command AntiVirus for OS/2
Command Software is proud to introduce Command AntiVirus 
version 4.58.3 with our HoloCheck(tm) scanning technology.
Our HoloCheck scanning technology detects tens of thousands
of viruses and includes improved polymorphic virus detection.
NOTE:  After installing Command AntiVirus, we recommend that you 
perform a manual scan of your local drives to ensure that your 
system is virus-free. This is especially important if you have 
not been running anti-virus software prior to this installation.
For a list of international distributors of Command AntiVirus,
see the DISTRIB.TXT file.
Presently, there is no documentation available for Command AntiVirus
for OS/2. However, you will find that Command AntiVirus for OS/2 
contains a graphical interface that is easy to use.
Command AntiVirus for OS/2 provides a 32-bit program and a 
command line scanner.

RELEASE NOTES
Notes on Command AntiVirus for OS/2 (CSAV) version 4.58.3
12/29/99
PRODUCT ENHANCEMENTS
Scan engine enhancements have been added to this component release.
FIXES
Performance issues were reported in relation to the default scanning of 
self-extracting files in Command AntiVirus 4.58. In CSAV 4.58.3, 
self-extracting files are no longer scanned by default.
NOTE:  To scan the contents of self-extracting files in zipped form, we 
       recommend that you perform an on-demand or scheduled scan of 
       Packed Files during off-peak hours. To scan self-extracting and 
       packed files select the Packed Files check box in the Properties 
       dialog box. 
SPECIAL NOTES
None for this release.

Notes on Command AntiVirus for OS/2 (CSAV) version 4.58.0
12/06/99
PRODUCT ENHANCEMENTS
New virus signatures have been added in this release. This includes
signatures for detecting more than 200 new trojans. 
The following improvements have been made to the scan engine:
- CSAV now detects malicious or destructive Java code (Java Trojans).
- The handling of script viruses is improved. This includes VBScript 
  viruses and ASCII-based viruses.
- CSAV now scans file attachments in Rich Text Format (.RTF) files.
  When scanning from the command line, use the /ARCHIVE switch.
- CSAV now disinfects Office 2000 signed documents.
- Scanning of the following is now supported:
    - OLE1 embedding (embedded files in WordPad and Microsoft 
      Word 6)
    - WordPerfect 2000 (.WPD) files
    - Lotus worksheets (.WKS) files
    - LX (OS/2) files as well as the detection of all OS/2 viruses.
- Some boot sector related disinfection problems have been fixed. The 
  most notable fixes involve disinfecting the Urkel and the
  Frankenstein viruses.
- PowerPoint scanning is improved. The disinfection process is revised. 
  However, the disinfection of objects embedded in PowerPoint documents  
  is still not possible.
- CSAV features improved scanning in Windows 32-bit programs resulting
  in higher rates of detection and fewer false positives.
- Memory scanning is improved.
- Disinfection of infected .VBS files by deletion is now supported.
The following file types are now hard-coded into CSAV and are scanned 
by default:
    EXE, COM, SYS, VXD, DLL, DRV, SCR, 386, OV?, CPL, FON, TSK, ACM, 
    ACV, TLB, TSP, OCX, VBX, VOM, VXE, OBJ, SHS, SMM, HLP, CLA, XL?,
    DOC, DOT, MDB, RTF, MPP, MPT, PPA, PPS, PPT, POT, WBK, PWZ, MSO, 
    OBD, OBT, OBZ, OFT, MSG, EML, TD0, BAT, BTM, INI, INF, HT?, VBS,
    GMS, CSC, WPD, WK?, DVB, WBT, and CDR
NOTE:  You can now add up to 20 user-defined file types in CSAV's 
       Files to Include dialog box.
A new virus definition file, SIGN2.DEF, is now included with Command 
AntiVirus. This file provides virus signatures for a variety of 
scripting viruses and trojans.
FIXES
Some command line scans using the /TODAY switch would not scan on 
the first boot of the following day. This was caused by CSAV's use of
Greenwich Mean Time rather than local time. This has been fixed.
SPECIAL NOTES
The self-extracting file called SE_EICAR.EXE is no longer included with
the installation files. You can download this file from our web 
site at: 
   http://www.commandcom.com/html/utils.html
When you run this file, a test file, EICAR.COM (from European 
Institute for Computer Anti-Virus Research), is extracted from it.

RELEASE NOTES
Notes on Command AntiVirus for OS/2 (CSAV) Version 4.57
07/12/99
PRODUCT ENHANCEMENTS
New virus signatures have been added in this release.
Command AntiVirus now includes expanded protection for the following:
   A. CorelDraw -- The newly discovered CorelDraw virus is now detected.
      The .CSC CorelDraw-related extension is now scanned by default.
   B. MacOffice -- Viruses in MacOffice documents can be detected and 
      disinfected. However, as the Macintosh(tm) operating system is 
      not directly supported by Command AntiVirus, detection is 
      possible only when the infected Macintosh Office documents 
      are scanned in a DOS or Windows-based environment. For example,
      if you have a floppy disk with infected MacOffice documents
      on it, you can disinfect these documents by using CSAV
      to scan the floppy disk.
   C. Microsoft Office 97 -- The .MPT, .WBK and .MSO extensions are now 
      scanned by default. 
   D. Office 2000 -- The heuristics scan engine has been modified so
      that it now detects some native Office 2000 viruses. 
   E. PowerPoint 97 -- PowerPoint 97 viruses are now detected and 
      disinfected. The .PP?, .POT, and .PWZ PowerPoint 97 file types
      are now scanned by default.
An additional generic virus detector has been added. This detector 
allows Command AntiVirus to detect approximately 14,000 more 
"generic viruses." This brings the total number of viruses detected 
by Command AntiVirus to just over 39,500.
The CSAV scanners have been optimized to provide better protection
against "New Executable" file viruses and VxD viruses. Improvements
have also been made to reduce the occurrence of false positives.
If you open an infected Microsoft Office 97 document in Microsoft
Office 2000, our HoloCheck scan engine will detect the infection.
Documents converted to Office 2000 format from Office 97 format
can be disinfected. Currently, disinfecting an Office 2000 document
consists of removing all macros from the document.
The Virus Information list is now generated from the CSAV definition 
files on your system. This allows you to view the names of all 
computer viruses that are handled by Command AntiVirus. To always
have the latest Virus Information list, be sure to keep your 
definition files up-to-date. 
Files that do not have a file name extension are now scanned 
by default.
FIXES
None for this release.
SPECIAL NOTES

Notes on Command AntiVirus for OS/2 (CSAV) 
Version 4.54 SP2 (Service Pack 2)
03/11/99
PRODUCT ENHANCEMENTS
New virus signatures have been added in this release.
The following default extensions have been added: .VXD and .386.

FIXES
When scanning in disinfect mode, sometimes the message 
"Virus could not be removed" would appear in the output window. 
Since the file was not infected, the error message was incorrect. 
Notes on Command AntiVirus for OS/2 (CSAV) 
Version 4.54 SP1 (Service Pack 1)
02/02/99
PRODUCT ENHANCEMENTS
New virus signatures have been added in this release.
SCR (screen saver) and RTF (Rich Text Format) files are now
scanned by default. SCR files are scanned because they
are susceptible to some Windows 95/98 viruses. RTF files are
scanned because infected DOC files that have had their extensions 
changed to "RTF" can still infect other Word documents and
templates.
CSAV now scans for ASCII-based viruses such as BAT viruses, 
JavaScript viruses and malicious applications, and VBScript viruses.
CSAV also detects mIRC scripts containing malicious code.
Better detection for Excel macro and field viruses has been added.
The scanning of MDB files is improved. 
Disinfection for polymorphic viruses such as W97M/Class that are 
found in the wild is new and improved. Selective disinfection allows
you to remove the macro virus and all traces of the disinfection
process. In password-protected documents, CSAV removes the virus but 
leaves traces of the disinfection process behind. In both instances,
the original document is preserved.  
FIXES
None for this release.
SPECIAL NOTES
To update Command AntiVirus with this service pack, you must run
the service pack's SETUP.EXE program. Note that only the 
components that require updating will be modified. 
Notes on Command AntiVirus for OS/2 version 4.54
12/04/98
PRODUCT ENHANCEMENTS
New virus signatures have been added for this release.
The scan engine has been optimized for faster scanning.
This includes faster scanning of a wider variety of compound 
files such as Microsoft Word and Excel files.
Command AntiVirus for OS/2 now detects Java viruses and 
Access 97 viruses. Disinfection ability will be added in an 
upcoming release.
Additional support for compressed executable files has been added. 
Specifically, compressed executables are scanned in memory. This
allows for faster scans of compressed files.
FIXES
None for this release.
SPECIAL NOTES
Microsoft Access (MDB) database files are now scanned by default. 
If you determine that real-time scans are noticeably slower, remove 
the .MDB extension from the Files To Include list. Then, create a 
scheduled scan task that periodically scans all the files in your 
Microsoft Access folders.

Notes on Command AntiVirus for OS/2 Version 4.51
07/14/98
PRODUCT ENHANCEMENTS
Command AntiVirus boasts our HoloCheck(tm) scanning technology,
providing the most up-to-date virus protection. The most important
benefits of this technology are: 
  *  Simplified updates. You can now update the SIGN.DEF and 
     Macro.def files (which contain the most current virus signatures) 
     without reinstalling all of the components. This method adds 
     speed and efficiency to the new version of Command AntiVirus.
  *  Superior polymorphic virus detection. CSAV now offers 
     unparalleled protection and elimination of polymorphic viruses 
     including the dreaded Morphine, Anxiety and Spanska.
  *  Scanning of embedded (OLE) documents. Not only do we scan 
     documents, but if an infected document is embedded in an Excel 
     spreadsheet or PowerPoint document, Command AntiVirus will catch 
     it and save you from becoming infected.
  *  Support for nested zip files.
SPECIAL NOTES
Currently, CSS Central does not support OS/2.
