Randomize scan times.

You can randomize scans to reduce processor loads and hypervisor resources.

See Randomizing scans to improve computer performance in virtualized environments.

Prevent known-clean files from being rescanned.

The Shared Insight cache keeps track of which files in the virtualized environment are known to be clean. Scan times are reduced by eliminating the need to rescan known-clean files.

See About the Symantec Endpoint Protection Shared Insight Cache tool.

Prescan base image files to reduce client scan times.

The Symantec Endpoint Protection virtual exception tool lets you safely remove base image files from the scanning process, which saves time and eases processor loads.

See Using the Virtual Image Exception tool on a base image.
