New features

Here is a list of features included with Patch 3.

Support for Windows 8

This release of VirusScan Enterprise:

Uses toast notifications (popup messages) to alert you to messages from the VirusScan Enterprise On-Access Scanner.
Integrates with the Windows Action Center (WAC).

You can view messages and resolve problems reported by VirusScan Enterprise from the Security area of the Action Center. For example, when VirusScan Enterprise is out of date, a message appears in the Action Center.

Supports the Windows 8 Early Launch Anti-Malware (ELAM) feature.

The ELAM driver (signed by Microsoft) starts anti-malware software before any third-party boot drivers, logs all drivers and executables loaded during boot and, once the system is booted, passes the list to VirusScan Enterprise for scanning.

If you suspect a rootkit is present:

1Verify that your detection definition (DAT) files are up-to-date.
2Restart the system to enable VirusScan Enterprise to identify any drivers that need to be scanned.
3Restart again to allow ELAM to block the identified rootkit drivers from loading.
Does not include the Buffer Overflow Protection (BOP) feature.

See Policy settings changes for policy changes.

NoteMcAfee Host Intrusion Prevention 8.0 Patch 3 will include support for BOP on Windows 8 and Windows Server 2012.
VirusScan Enterprise Patch 3 no longer disables Microsoft Windows Defender during installation to Windows 8 and Server 2012 systems.

Connected standby mode

This release of VirusScan Enterprise provides support for systems in connected standby mode (also called Always On Always Connected or AOAC).

Note AOAC mode is only supported on Windows 8 systems with hardware chips that support AOAC.
AOAC suspended mode

When the system is in AOAC suspended mode, VirusScan Enterprise does not perform scans or DAT updates. If an on-demand scan (ODS) starts before the system hibernates in AOAC or battery mode, the ODS pauses. If Run missed tasks option is selected, any missed ODS scans run immediately when the system wakes from suspended mode.

User present mode

When a user is present (keyboard and/or mouse interaction within 5 minutes), VirusScan Enterprise performs any on-demand scans and DAT updates as specified by the schedule.

Cookie scans have been removed. Scan cookie files on the On-Access Scan Properties | General Settings | General tab Scan cookie files on the On-Access General Policies | General tab
Artemis (GTI) sensitivity level is now set to Medium by default for new installations only (not upgrades).
NotePolicy settings in McAfee ePO override this default.

Registry settings changes
New or changed setting Registry entries DWORD default value
Delayed Write Scan mode is now enabled by default.

This mode delays all scans of modified files to lower priority background threads. This improves performance for processes that write data to disk frequently and/or write a lot of data in a short amount of time.

Important To maintain security, you must enable the Scan on Read setting.

Removable media and network file share write operations are still scanned immediately on Close.

Rootkit Detection mode is now enabled by default.

On-Demand Scanner is now limited to one thread per CPU, 6 threads total by default. This limits the amount of memory used by ODS.
To activate this feature, the System utilization slider setting (on the On-Demand Scan Properties, Performance tab) must be set to Below Normal.
To change the maximum number of threads, set the DWORD value.
To deactivate this feature, set the DWORD value to "0".

Artemis performance is increased when scanning large files.
Large files are now hashed and, in parallel with the scan, an Artemis query runs to determine whether the file is known to be clean. If so, the scan stops.
NoteThe Artemis query runs regardless of the sensitivity level.
Because hashes are cached, future scans can use the existing hash if the file hasn't been modified.

By default, files larger than 5MB are hashed. To specify the size of files that trigger this behavior, set the DWORD value.
