These release notes cover what is new in V2.2.3 (9506) of VirusScan
for DOS, VirusScan for Windows, VirusScan for OS/2 and VShield.

This release is a combination DAT file and executable release. The
DAT file changes are listed below. The following viruses are
dependent on having the most up to date executable (2.2.2+) with the
most up to date DAT files (9506):

Neuroquila
OneHalf
Urkel

NOTE: The version number of VShield in this release is 2.2.2.

Code changes incorporated into V2.2.3:

1. Addressed problems with /FREQUENCY switch.
2. Addressed problems with speed when SCAN occurs while VShield is loaded.

Code changes incorporated into V2.2.2:

1. File cleaning occurs until the last virus that can be removed, is
removed from the file. (Multilevel cleaning for multiply infected
files.)
2. Speed improvements depending on your environment.
3. Memory scanning default to not scan from 640K, picking up again at
segment FFFF. See MEMEXCL option for details.
4. Added new option /NODDA. (Needed for NT or any 32 bit file system
to allow scanning without stopping on the attempt to scan the master
boot record. Such systems prevent 16 bit access to the MBR.)
5. Added new option /CONTACTFILE. (For corporate customers, allows you
to add your own site message.)
6. Modified /BOOT functionality. (If DOS 4+ does not recognize the
diskette, try scanning the diskette with /BOOT.)
7. Added new option /LOCK. (Instructs scan to lock up the computer when
a virus is found.)

NOTE: Beginning with the May release of McAfee Anti-Virus Products,
the Virus Data File numbering system has changed. The previous
format was to include the DAT file revision in parentheses after
the program revision as a 3 digit number that indicated numeric
file revision. For Example:
2.2.0 (221)
indicated DAT file revision number 221.

In this new format, the DAT file revision is a 4 digit number,
indicating the year and month of the release as in:
2.2.0 (9505)
This indicates executable revision 2.2.0, and a data file released in
May of 1995.
