- Virus Central v1.23
-
-
- * The following files are on the Virus Central distribution
- disk:
-
- CENTRAL.EXE - Virus Central executable program
- CENTRAL.CFG - configuration file
- CENTRAL.DOC - Virus Central user's manual
- REGISTER.DOC - registration information form (share-ware
- version only)
- README.1ST - late breaking news! (this file)
-
-
- * Some portions of the Virus Central user's manual use the
- IBM extended characters. Be aware of this if the printout of
- the manual looks funny.
-
-
- * The virus list contains the viruses that apply to CleanUp 67.
- If a newer version of the CleanUp program is released, you may
- add on the newer viruses to this list. Whenever new versions
- of Virus Central will be released, the virus list will be
- amended to reflect the most current version of CleanUp.
-
-
- * You may use the VALIDATE.COM program (included with your copy
- of ViruScan and/or CleanUp) to test the integrity of Virus
- Central. Take note that the share-ware and registered user's
- versions of the program yield different results, because of
- the share-ware notice on the latter.
-
- Here are the validation results of the share-ware and
- registered user's versions of Virus Central:

- ** Release Notes / Bug Fixes **
-
- As can be expected with ANY program, particularly the first
- releases, there will ALWAYS be bugs. Virus Central is no
- exception. To date, 4 bugs have been reported, and corrected,
- since the initial release of the program. I have decided to do
- away with my earlier practice of attaching letters to the
- version numbers of new releases since it causes confusion. I
- will, instead, adjust the version number to reflect the
- magnitude of modification.
-
- Virus Central Release Notes:
-
- v1.00A (08/02/90)
- A bug report (would you believe, the day after Virus Central was
- first released as a share-ware program) found that the program
- would flat-out refuse to run on MS-DOS 4.01. I realized early on
- in the project that Virus Central required at least MS-DOS 2.1
- to run properly, so I installed a routine to check the DOS
- version before anything else. I tested the program using DOS
- 2.1, 2.11, 3.2, and 3.3, and they all worked fine. I never
- tested Virus Central using DOS 4.01 because I do not have a copy
- of that version. After I received the report, I examined the DOS
- version checking routine again, found the error, and fixed the
- problem.
-
- ----------------------------------------------------------------
-
- v1.00B (08/08/90)
- Two bugs were reported, again relating to Virus Central's
- initialization routine. The program still refuses to run on some
- systems using DOS 4.01, although the earlier problem was
- corrected (a DOS bug, perhaps?). Another problem was that Virus
- Central would sometimes mistake a VGA card for a Hercules
- graphics card, particularly those that auto-sense and emulate.
-
- Both these problems were related to Virus Central's pre-system
- checking, which I still believe is a necessary step. I did not
- remove this feature, but I added an option to get around it. To
- bypass the pre-system check, from the DOS prompt, enter:
-
- CENTRAL /IGNORE
-
- When using the "/IGNORE" option, Virus Central does not check
- the system for compatibility. You should only use this option
- if you are sure that your system is compatible, but the program
- refuses to run. You may still specify the "/NOMOUSE" option, if
- so desired, by putting before the "/IGNORE" option in the
- command line (e.g. "CENTRAL /NOMOUSE /IGNORE").
-
- v1.03 (08/17/90)
- A bug in the string input routine prevented the [Del] key from
- working when it was on the last character of a string or number.
- This was, surprisingly, easy to fix, and I am embarrassed that
- it got away from me, in the first place. Also, the Virus List in
- the CENTRAL.CFG file was updated to reflect the new ones in
- ViruScan/CleanUp 66.
-
- ----------------------------------------------------------------
-
- v1.23 (10/07/90) << MODIFIED CONFIGURATION FILE FORMAT >>
- Another bug was fixed. Well, not really a bug. Well, sort of.
- Since it's initial release, Virus Central has had a side-effect
- that I have been aware of, but, up until now, have not been able
- to remedy. Because Central redefines a certain interrupt service
- routine (ISR), the DOS clock would occasionally stop, causing it
- to lag behind. This is a problem common to many memory resident
- type programs (Central uses some routines that are based on TSR
- techniques). Since I was aware of the problem and knew exactly
- what was causing it, I did not consider it to be a bug. It was,
- however, an annoying problem. A complete rewrite of the routine
- solved the problem, and increased the speed of screen output to
- the black box by 20%.
-
- This version of the program also adds support for the validation
- codes, extinct viruses, and scan report features of ViruScan.
- Take note, the configuration file format has been modified, and
- the configuration file used by earlier releases will not work
- right. A section has been added to the documentation describing
- the new format.
-
- Many users requested an option that would disable the screen
- saver from automatically kicking in. Since I have always felt
- that the screen saver is Central's most charming asset, I was
- extremely reluctant to do this. But I aim to please. Setting
- the screen saver time lapse to zero (0) disables it from
- kicking in automatically, although you may still invoke it
- manually (pressing the [B] key from the main menu, or clicking
- on the diamond in the upper left corner).
-
- To my embarrassment, I realized that I misspelled the name of
- the ViruScan program all over the manual, spelling it
- "VirusScan." This is hardly a bug, but it was worth correcting.
- Sorry, John.
-
- The virus list has been updated for ViruScan/CleanUp 67. And,
- just to get fancy, an openning screen has been added to the
- program, displaying the Virus Central trade mark.
