Support KnowledgeBase article KB51560 for information on ratings.
Improvements
Improvements made with this release of the software are described below:
1. The VirusScan Reports extension now has updated queries to show the status of Artemis settings for the on-

access, on-demand, and email scanners.
NOTE: The Artemis status requires VirusScan Enterprise 8.5i
Patch 8 or VirusScan Enterprise 8.7i Patch 1 to
be installed on the client systems, in order to correctly populate the reports. Refer to McAfee Support
KnowledgeBase article KB53732 for further information on Artemis functionality.
2. On-Access Scanner’s Artemis level setting is now modifiable via the properties UI, and the equivalent
VirusScan 8.7i NAP and Extension included in the patch package.
NOTE: Because this setting is new with this release of the VirusScan 8.7i NAP and extension, there is no
preserved setting upon check-in of the management package. The ePolicy Orchestrator administrator will
need to update that setting in the policies to match the current Artemis policy.
3. Several modifications have been made to the way VirusScan Enterprise interacts with the operating system
on startup, suspend, and shutdown. These modifications resolve and improve performance issues.
4. Current DAT files are compressed to conserve network bandwidth. Now, changes have been made to
decompress the DATs during the AutoUpdate process and leave them in that state, so that scanners do not
have to decompress them during initialization of the scan.
5. The on-demand scanner now uses Windows Priority Control setting for the scan process. This lets the
operating system set the amount of CPU time that the on-demand scanner receives at any point in the scan
process. The System Utilization setting in the On-Demand Scan Properties maps to Windows Priority Control
as:
6. The on-access, on-demand, email, and script scanners now use a runtime copy of the DATs. This change
has reduced the memory consumption of affected scanners by having the DATs in a readily available state
for the scan engine to load.
NOTE: In some scenarios, the runtime DATs are not available. See item #1 under Known Issues. Refer to
McAfee Support KnowledgeBase article KB65459 for further information on runtime DATs.
7. VirusScan Enterprise functions that request the current version of DATs no longer need to initialize the scan
engine to do so. This prevents excessive
CPU spikes during ePolicy Orchestrator properties collection, as well
as other areas that poll the DATs.
8. The on-access scanner memory scan function (Processes on enable) has been
modified significantly to make
it more comprehensive.
NOTE: The improved functionality can cause a performance impact to the system. See item #2 under
Known Issues.
9. When a web browser opens a site that is script-intensive, scanning the scripts adds to the delay of loading
the page. This Patch contains new functionality for ScriptScan whitelisting. If the web site is a trusted
Intranet and/or frequently visited, the new implementation now allows for the
exclusion of that the site from
script scanning.
NOTE: Refer to McAfee Support KnowledgeBase article KB65382 for further information.
10. The installation packages for patches and reposts have been upgraded so that the installation log name,
created in the McAfeeLogs folder, has a dynamically generated name based on the current date and time of
the installation. This helps save logs that might have been overwritten with the previous “backup previous
log only” method.
Known issues
Known issues in this release of the software are described below:
Utilization Priority
10% Low
20%-50% Below Normal
60%-100% Normal

1. Issue: In some situations, the product switches over to using the normal copy of the DAT files, instead of
the runtime DATs:
{If the McAfee AntiSpyware Enterprise module is installed after VirusScan
Enterprise 8.7i Patch 1 is on
the system, some of the new registry settings, which are new for the runtime functionality, were
changed back. This resolves itself with a restart of the McTaskManager service or with a reboot.
{If one of the scanners is busy on a large file when the AutoUpdate process posts the revised copy of
the DATs, the process of refreshing the runtime copy of the DATs times out. All scanners use the
normal DATs until the next successful update.
{The VirusScan Modules* will not use the runtime DAT functionality until they received their next
Patch.
2. Issue: With the improved functionality of the on-access scanner memory scan, lower and middle ranged
systems may see a performance impact at startup and after a successful AutoUpdate of the engine or DATs.
Currently the Process on enable option is enabled by default on the shipping version of VirusScan Enterprise
8.7i. McAfee recommends that in a managed environment, disable this option prior to deployment of the
Patch, until the impact of memory scanning can be determined for your environment. It is not possible to
maintain both the more comprehensive scanning that comes with Patch 1 and later, and the former level of
scanning. Therefore, only the more comprehensive scan is used.
NOTE FOR CURRENT AND NEW USERS:
{The Patch installation does not modify current settings to disable the Process on enable option.
{The VirusScan 8.7i NAP and extension that are included with the Patch do change the McAfee Default
policy, but do not modify the My Default policy,
or any custom policy settings that were made prior to
the checkin of the new NAP/extension.
{The VirusScan Enterprise 8.7i Repost with Patch now installs with the Process on enable option
disabled, unless the Maximum Security option is selected during the installation.
3. Issue: VirusScan 8.7i Patch 1 introduced an issue with Microsoft Outlook where keyboard entries made
during the delivery of an email were lost.
NOTE: This issue is resolved by HotFix VSE85HF464768, included with this release. Refer to "Additional
Steps for HotFix 464768" for installation instructions.
4. Issue: The Access Protection rule "Prevent termination of McAfee processes" was improperly disabled, on
32-bit systems, even when the managed policy specified otherwise.
NOTE: This issue has been resolved in the fully released version of the Patch. HotFix VSE85HF464768,
included with this release, resolves the issue for customers who installed Patch 1 during the managed
release cycle. Refer to "Additional Steps for HotFix 464768" for installation instructions.
5. Issue: The Patch installer included an MSI deferred action to resolve an issue found when attempting to
uninstall the Patch on some newer operating systems. The deferred.mfe file updated the cached MSI of the
currently installed VirusScan 8.7i product. If the Patch is included in a McAfee Installation Designer
customized package, the deferred.mfe file was not
included, and therefore the Patch might not be able to be
uninstalled in some newer operating systems.
6. Issue: If you installed this release interactively and cancelled the installation on a system where a previous
Patch was installed, after the rollback was complete, the previous Patch might no longer reported to ePolicy
Orchestrator or appeared in the About VirusScan Enterprise window.
7. Issue: Installing the Patch and specifying a log file path using the Microsoft Installer (MSI) switch “/L” did
not log to the specified path. A log file capturing full data was logged to the folder “McAfeeLogs” under the
Temp folder.
8. Issue: If Host Intrusion Prevention 6.x or later was installed and disabled prior to installing VirusScan
Enterprise, it was necessary to re-enable Host Intrusion Prevention and disable it again, in order for
VirusScan Buffer Overflow Protection to be properly enabled.
9. Issue: Uninstalling VirusScan Enterprise Patches is possible for computers running Windows Installer v3.x
or later. This technology is not fully integrated for Windows 2000 operating systems, so there is no option to
remove the Patch in Add/Remove programs. See instructions under Removing the Patch for removal via
command-line options.
10. Issue: Patches for VirusScan Enterprise 8.7i can only be uninstalled via Add/Remove programs, not via
ePolicy Orchestrator.

Resolved issues
The resolved issues are divided into subsections per patch, showing when each fix was added to the compilation.
Patch 1 resolved issues:
1. Issue: An unauthenticated remote denial-of-service attack was discovered. (Reference: 470184)
Resolution: The product no longer allows the denial-of-service attack.
2. Issue: Under certain conditions, the Lotus Notes scanner of VirusScan Enterprise can mistakenly deny
access to the Lotus Notes internal processes, if a note was being accessed more than once. (Reference:
438541)
Resolution: The Lotus Notes scanner has been adjusted to better handle re-entrance scanning of the same
note.
3. Issue: Silent installs may fail on hard drives that are designated as dynamic. The on-access scanner service
fails to start, and the installation will roll back. (Reference: 443669)
Resolution: The patch 1 and later install packages will now install to a dynamic disk, silently.
4. Issue: Sporadic crashes were seen on multi-processor systems, with the Lotus Notes scanner file
ncdaemon.exe, during startup and general use of Lotus Notes. (Reference: 442337)
Resolution: The Lotus Notes scanner has been corrected to prevent a race condition where different
scanner threads were starting and stopping out of sequence.
5. Issue: A 8E bugcheck (blue screen) sometimes occurred when
VirusScan Enterprise 8.7i was installed along
with Checkpoint VPN-1 SecureClient. (Reference: 438771)
Resolution: The link driver was updated to avoid probing kernel memory unnecessarily.
NOTE: For this fix to prevent the above issue, the files need to be placed on the system during the
installation of VirusScan Enterprise, before the services start. The repost of VirusScan Enterprise 8.7i with
Patch 1 will be needed to see the resolution.
6. Issue: A flaw in the caching algorithm sometimes caused files in removable media to not be scanned.
(Reference: 443104)
Resolution: The Anti-Virus Filter driver was updated to clear the cache of removable media upon attaching
to the system.
7. Issue: The on-access scanner contained a flaw in the scan on close logic. This could cause a file to be
queued up for scanning a second time. (Reference: 434475)
Resolution: The Anti-Virus Filter driver no longer queues these unnecessary scan requests.
8. Issue: During an upgrade from a customized VirusScan Enterprise 8.5i to VirusScan Enterprise 8.7i, An
issue sometimes occurred where the configuration tool did not properly backup and restore the registry
information. The installation was left in a state where some of the product information still showed as the
older version. (Reference: 443019)
Resolution: The McAfee Installation Designer configuration applicator has been changed to be more
comprehensive in backing up and in version checking during the upgrade, in order to prevent failures by
other McAfee product installations that require version 8.7i.
NOTE: For this fix to prevent the above issue, the files need to be placed on the system during the
installation of VirusScan Enterprise, before the services start. The repost of VirusScan Enterprise 8.7i with
Patch 1 will be needed to see the resolution.
9. Issue: On Microsoft Windows Vista SP1 or 2008 server, sharing violations could occur when working with
remote files while network drive scanning was enabled. This resulted in being denied access to files, or being
unable to modify or save a file. (Reference: 447282)
Resolution: The Anti-Virus Filter driver has been updated to better handle potential sharing violations that
could occur and avoid conflicts.
10. Issue: Prolonged use of the VirusScan Console was causing delays in loading subsequent loading of the
Console window. (Reference: 456831)
Resolution: The VirusScan Console plug-in was corrected to properly clean up the .tmp files it creates at
load time.

11. Issue: Access Protection rules were being triggered during creation of a VirusScan customized installation
package via McAfee Installation Designer. This could lead to a crash of the McAfee Installation Designer tool.
(Reference: 435728)
Resolution: The VirusScan Email Scan library appropriately handles the new Sensitivity level setting when
it is displayed in the McAfee Installation Designer window.
12. Issue: Certain detections with multiple infections or clean actions were logging the action two times. One
entry was made during the middle of the process, and the other during the final resolution. (Reference:
404787)
Resolution: The Common Shell scanner has been updated to report only the final resolution of the
detection.
13. Issue: A 8E bugcheck (blue screen) might occur during the “Memory for Rootkits” portion of an on-demand
scan. (Reference: 445490)
Resolution: The code analysis driver now uses a more robust method of querying the system for driver
object data.
14. Issue: Access Protection block rules that were created for USB devices sometimes did not handle removing
and reinserting the device multiple times. (Reference: 457415)
Resolution: The Access Protection, Anti-Virus Filter, and Link drivers have been updated to better handle
reinserting the device.
15. Issue: The on-access scanner was not properly utilizing the Scan files opened for Backup option.
(Reference: 457416)
Resolution: The Anti-Virus Filter driver has been rectified to properly interpret the flag being sent from the
on-access scanner.
16. Issue: In an ePolicy Orchestrator managed environment, the agent’s Collect and Send Properties function
could cause the McAfee Product Manager service to spike its CPU utilization for extended periods of time.
(Reference: 457421)
Resolution: The VirusScan Management Plug-in has been updated to call for the scan engine and DAT files
via a new API call, rather than initializing the engine to retrieve the information. This lessens the CPU time
involved during the agent Collect and Send Properties function.
17. Issue: With certain Access Protection rules enabled, VirusScan Enterprise was failing to return information
to the Checkpoint SecureClient software. (Reference: 444667)
Resolution: The binaries for Checkpoint integration have been updated to properly request information
from VirusScan Enterprise.
18. Issue: Attempting to start an on-demand scan via the VirusScan tray icon could result in an error on
Microsoft Windows Vista. (Reference: 446950)
Resolution: The VirusScan tray icon correctly calls the on-demand scanner on User Access Controlled
operating systems.
19. Issue: Creating a McAfee Installation Designer change package for VirusScan Enterprise and the
AntiSpyware Enterprise Module, sometimes failed to upgrade the evaluations to licensed versions, for both
products. (Reference: 437509)
Resolution: McAfee Installation Designer configuration applicator upgrades the licenses of VirusScan
Enterprise and the AntiSpyware Enterprise Module when they are both evaluations.
20. Issue: The VirusScan Console On-Delivery Email Scanner entry was not worded correctly in German.
(Reference: 438931)
Resolution: The VirusScan Resource file updates the displayed text to the correct wording in German.
21. Issue: One of the ScriptScan “McLogEvent” entries was always recorded in English. (Reference: 431071)
Resolution: The Announcer library was updated to remove the extra notification.
22. Issue: In some cases, VirusScan Enterprise was not properly displaying Patch information about itself and
currently installed VirusScan Modules*. (Reference: 456826)
Resolution: The VirusScan Management Plug-in has been updated to gather the current information about
Patch levels of its installed VirusScan Modules*.
23. Issue: When there were HotFixes or Patches available for the VirusScan Modules*, they were not being
downloaded to the clients. (Reference: 445494)
Resolution: The AutoUpdate binary was modified to check for the existence of the VirusScan Module*

licenses when deciding which HotFixes or Patches to install.
24. Issue: Script errors were seen when attempting to view the Japanese text, of the product description
window, in ePolicy Orchestrator 3.6.x. (Reference: 434203)
Resolution: The VirusScan 8.7i NAP file has been updated to display the Japanese page in its proper
Unicode format (UTF-8).
25. Issue: The alert options for Network Appliance Filer and ICAP scanners were visible on the workstation
ePolicy Orchestrator policies. (Reference: 448361)
Resolution: The VirusScan 8.7i NAP and extension have been updated to remove the alert options for alert
options for Network Appliance Filer and ICAP scanners, from the workstation policy, as those scanners are
server specific.
26. Issue: Some ePolicy Orchestrator operational events were not being
generated for the VirusScan Modules*.
(Reference: 434423)
Resolution: The VirusScan Reports extension updates the current VirusScan Enterprise Event IDs (1329 –
1339) to be used for the VirusScan Modules*.
27. Issue: The on-demand scan log file validation checked for invalid file characters, including the "<" and ">"
characters. (Reference: 433776)
Resolution: The VirusScan 8.7i extension validation for the path name of the on-demand scanner log file
now allows the "<" and ">" characters, which are needed for ePolicy Orchestrator macro variables.
28. Issue: The alert options for the VirusScan Modules* would not gray out when inheritance was enforced on
the parent policy. (Reference: 434231)
Resolution: The VirusScan 8.7i NAP now properly enforces inheritance on the VirusScan Module alert
options.
29. Issue: Events generated by the VirusScan Enterprise for Offline Virtual Images 1.0 software were not being
generated in ePO reports. (Reference: 439832)
Resolution: The McAfee Announcer library changed properties of the events to support current reporting in
ePolicy Orchestrator 3.6.1.
30. Issue: Scanning events generated by VirusScan Enterprise 8.7i were not populating the Task Name with
proper information. (Reference: 453515)
Resolution: The McAfee Announcer library now populates the Task Name with the scanner that generated
the event.
31. Issue: The Access Protection includes and exclude fields permitted a limited number of characters in the
extension interface. (Reference: 457418/457419)
Resolution: The VirusScan 8.7i extension updates the maximum limit of the include and exclude fields, to
be consistent with the point-product interface.
32. Issue: Scanner exclusions that were entered in ePolicy Orchestrator with a preceding blank space did not
show up correctly when they were enforced on the client. (Reference: 457420)
Resolution: The VirusScan 8.5i extension has been updated to strip any preceding blank spaces from
exclusions when they are entered in ePolicy Orchestrator.
33. Issue: VirusScan Enterprise added some new events that were not
included in the default event filter, which
was provided by ePolicy Orchestrator. (Reference: 462927)
Resolution: The VirusScan Reports extension updates the current list to allow filtering of these events.

Step 1 to your repository.
4. Refer to the HotFix readme HF464768.htm for further details on the HotFix.
HotFix and Patch reporting
There is HotFix/Patch information in the ePolicy Orchestrator properties for each computer. On the ePolicy
Orchestrator Properties tab for each computer, the VirusScan 8.7i General branch displays two entries:
zPatch – Displays the current Patch installed.
zFixes - Displays any number of HotFixes listed in the registry.
A check is involved to verify that the HotFix/Patch matches the entry in the registry to the private build description
of the binary. If the two don’t match, the Patch or HotFix does not appear.
NOTE: Currently there are no reports or compliance checks that use this information.
Verifying Installation:
Always reboot prior to validating that a Patch has been installed successfully.
1. Open the VirusScan Console and select About from the Help menu. The About VirusScan Enterprise window,
Installed Patches, displays “1.”
2. After property information has been collected by ePolicy Orchestrator agents, the client systems show that
Patch 1 is installed as the “Hotfix” version. If the value HotfixVersions appears, it is a temporary value and is
removed after a full property collection from the client.
3. Confirm that the expected files are installed by checking the version number of individual files. File versions
should match the list of files in Patch Inventory, above.
NOTE: Patch releases do not display or report that the Patch is
installed if an error occurred during installation, or i
f
a file or files did not install correctly.
Removing the Patch
Windows Installer 3.x and later now support the rolling back of Patches. This can be done one of two ways.
zFor Windows XP, Windows 2003, Windows Vista, and Windows 2008 operating systems, the Patch can be

removed manually via Add/Remove Programs if the user has administrative rights to the local system.
zFor all operating systems that support Windows Installer 3.x, a command-line option can be used to remove
the Patch silently.
Example:
C:\WINDOWS\system32\Msiexec.exe /I {147BCE03-C0F1-4C9F-8157-6A89B6D2D973} MSIPATCHREMOVE=
{6D622ACA-CAEF-455E-A108-E2953C0683A0} /q
Considerations:
1. The GUID information used here changes from one Patch to another. Always use the information in the
Release Notes for the Patch that you are removing.
2. Because the Patch is removed via MSIEXEC, the functions inside setup.exe, which normally prevent reboots
from occurring during silent processes, are not executed. In order to prevent a possible automatic reboot
from occurring after a Patch removal, simply add the REBOOT=R parameter to the command-line option
above.
3. Patch removal is an MSI reinstall function. When a Patch is removed, all features affected by the Patch are
reset to installation defaults. Any features not modified by the Patch are left with their current settings.
4. Update VirusScan after removing the Patch to ensure that the latest
versions of the engine and DAT files are
run.
