The AV Signature Pack is not packaged with the sensor installation, but should be downloaded and installed automatically after sensor installation based on policy settings.
The AV Signature Pack requires approximately 120MB at rest. During run time, 400MB is required because a second copy is created; the scan continues to function while signatures are being updated. After the update is complete, the old signatures are deleted. At least 200MB of memory is required to run the local scan.
Signature file updates are ON by default via a policy setting. You might encounter high bandwidth utilization upon sensor installation due to the initial signature file download. Subsequent updates following the initial install of the AV Signature Pack are differential. Therefore, setting a regular update schedule ensures that every subsequent update remains small.
To avoid network saturation during sensor installation, we recommend that you install sensors in small batches.
