System Watcher

Expand all | Collapse all

The System Watcher component receives data on the actions of applications on your computer and provides this information to other protection components to improve their performance. The System Watcher component uses applications' Behavior Stream Signatures (BSS). If application activity matches a behavior stream signature, the Kaspersky application performs the selected response action. The Kaspersky application functionality based on behavior stream signatures provides proactive defense for the computer.

By default, System Watcher is enabled and runs in the mode recommended by Kaspersky experts. You can disable System Watcher if necessary.

Enable/disable System Watcher

As a result, if System Watcher is enabled, the Kaspersky application uses behavior stream signatures to analyze applications' activity in the operating system.

Important: We do not recommend to disable System Watcher unless absolutely necessary because doing so will reduce the effectiveness of protection components. To detect threats, the protection components may request data collected by the System Watcher component.
