Additional change
If you still experience unresponsiveness, McAfee recommends you change the way the DATS
are being consumed by the engine. Before you make this change you should understand that
it increases your system:
• Boot time, by at most 10%
• Peak memory consumption of McShield by four times the current amount
NOTE: This setting is suggested for systems that do not have tight memory requirements
and boot time restriction.
Change the way the VirusScan Enterprise engine consumes the DATs using the following:
1 Start the windows Registry Editor and navigate to the following local machine key:
HKLM\SOFTWARE\McAfee\SystemCore\Vscore\NoRuntimeDats
2 Change the default registry value to 2.
3 Reboot the system for the registry setting change to take effect.
Configuring the scan cache
The VirusScan Enterprise scan cache saves a list of scanned files that are clean. This improves
your system performance by saving this clean file scan cache information during a system
reboot. This also allows the on-demand scanner to use this clean file cache information to
reduce duplicate file scanning.
These options should remain enabled for the best boot time and overall system responsiveness
during on-demand scans.
NOTE: Disable these settings during a malware outbreak or if your security requirements are
high.
