Enable or disable proactive scanning

Proactive protection in cPFence v4+ changes scanning behavior for faster detection. It depends on malware real-time protection and an eligible license.

Using the WebUI

1. Open Threat & Malware Detection, choose the server and open Settings.
2. Set Proactive Protection, then Save.
3. Confirm the saved switch and review the protection card.

For several servers, use Advanced Tools → Manage Proactive Protection, checking the sidebar targets and each result. Support users need protection-setting permission.

Proactive Protection settings. Shown values can differ from fresh defaults. Select the image for full size; use browser Back to return.

To restore this page’s defaults, follow reset feature-page settings.

Using the CLI

Run as root on the target server:

Action	Command
Enable proactive scanning	cpfence --enable-proactive
Disable proactive scanning	cpfence --disable-proactive

Servers with limited resources

Turn proactive scanning off if the server has limited memory, few CPU cores or slow disks. Leave capacity for websites and mail. More swap does not replace adequate RAM.

The fresh default is on, but license and resource checks still apply. Disabling proactive protection leaves the two-minute MRTP timer available. Review scan health before starting additional work.
