- NEW INSTALLER
- =============
-
- The latest installer for Dr Solomon's Anti-Virus Toolkit comes with
- the option to install the memory resident scanner, VirusGuard, in
- three different modes:
-
- 1. Maximum security
- 2. Standard security (default)
- 3. Minimum security
-
- 1. Maximum security:
- VirusGuard is installed in AUTOEXEC.BAT with the following switches:
- /COPY=ALL /WRITE=ALL
-
- This means VirusGuard will check all files copied and all files
- written to disk. This will have an impact on system performance,
- but offers maximum protection. Floppy disks are checked for boot
- sector viruses on access. All files will be checked when executed.
-
- 2. Standard security:
- This is a standard VirusGuard installation which has been used in
- previous versions of the Anti-Virus Toolkit. No parameters are
- passed to the VirusGuard program. All executable files are checked
- when copied and when executed. Floppy disks are checked for boot
- sector viruses when accessed.
-
- 3. Minimum security:
- VirusGuard is installed in AUTOEXEC.BAT with the following switches:
- /COPY=FLOPPY /WRITE=NO
-
- This means VirusGuard will only check files for viruses under the
- following conditions:
-
- .. Files are checked when copied from a floppy disk
- .. Files are checked when executed
-
- Floppy disks are also checked for boot sector viruses when accessed.
-
-
- Further discussion of VirusGuard can be found in the Toolkit manual.

- NEW FINDVIRUS OPTION: /UNPACK
-
- Scanning archived files:
-
- FindVirus now has an additional switch: /UNPACK. This feature is only
- available in the DOS version of FindVirus.
-
- The unpack option tells FindVirus to scan executable files within
- archived files. Archived files are decompressed to a temporary
- directory on a hard disk or network drive.
-
- To handle the many different and new archiving formats FindVirus
- needs to be configured with the file FINDVIRU.INI.
-
- Example of FINDVIRU.INI:
-
-
- [Options]
- TMPDIR=C:\TZ
- ZIP=PKUNZIP.EXE %s *.EXE *.COM /d C:\TZ
- ARJ=ARJ.EXE E %s C:\TZ
- LZH=LHA.EXE x %s C:\TZ\ *.EXE *.COM
-
- TMPDIR points to the temporary directory to which you wish to
- decompress archived files. The temporary directory must exist
- before you run FindVirus with the /UNPACK option. FindVirus
- will automatically remove files from this temporary directory
- so be careful to make sure there is nothing useful in it.
-
- ZIP=, ARJ= and LZH= are examples of compressed file extensions. When
- FindVirus comes across files with these extensions it will attempt
- to decompress them to the temporary directory using the command
- line given.
-
- Thus,
-
- ZIP=PKUNZIP.EXE %s *.EXE *.COM /d C:\TZ
-
- Tells FindVirus to execute PKUNZIP (which should be in the same
- directory as FindVirus), substituting the filename for %s, with the
- parameters "*.EXE *.COM /d C:\TZ"
-
- FindVirus /UNPACK will only work from write-enabled media.
- ------
- TKUTIL V1.55 now has the option:
-
- TKUTIL ADUPDATE dest src
-
- Both UPDATE and ADUPDATE options return the following set of errorlevels
- The DOS version/checksum failure level is returned regardless of the
- switch given to TKUTIL. The important part is the first four errorlevels, which
- indicate whether anything has been done.
-
- The errors which aren't generated relate to the command-line, which is handled
- differently by TKUTIL.
-
-
- 0 : Nothing done
- 1 : Files update but not copied
- 2 : Files copied but not updated
- 3 : Files copied and updated
- 5 : Invalid source directory
- 6 : Invalid destination directory
- 11 : Insufficient memory
- 12 : Source and destination directories identical
- 14 : Error during copy
- 17 : Empty source directory (during file add only)
- 18 : Empty destination directory (during file update only)
- 255 : DOS version/checksum failure
-
- TKUTIL LASTRUN can now have the format:
-
- TKUTIL LASTRUN filename
-
- This will cause TKUTIL to use filename to store its date stamp information rather
- than the default TKUTIL.DAT. Thus TKUTIL can now be used to time multiple events.
- If TKUTIL cannot find its data file it will return errorlevel 254.
-
- TKUTIL V1.58 now has the option:
-
- TKUTIL ADD filename 'phrase' </START> </END> </AFTER> <'phrase2'>
-
- NB. The quotes have to be single (') quotes, NOT double (")and must always be present.
-
-
- Examples:
-
- TKUTIL ADD C:\AUTOEXEC.BAT 'guard /copy=floppy' /START
-
- Adds "guard /copy=floppy" to start of AUTOEXEC.BAT if its not already
- there.
-
-
- TKUTIL ADD C:\AUTOEXEC.BAT 'guard /copy=floppy'
-
- Adds "guard /copy=floppy" to end (the default) of AUTOEXEC.BAT if its
- not already there.
-
-
- TKUTIL ADD C:\AUTOEXEC.BAT 'guard /reguard' /after 'login'
-
- Adds "guard /reguard" to AUTOEXEC.BAT after the line which says
- 'login'
-
-
- Errorlevels returned:
-
- 1: Incorrect parameters
- 2: Filename not found to munge
- 3: Error reading file
- 4: Error writing file
- 5: Not added, because the 'after' line wasn't found.
