System Security

Enable System Security: turns on/off the System Security monitoring component. By unchecking this box, you will stop all the three modules of the System Security protection. Disabling the System Security protection is not recommended, as it will expose your computer to serious security risks.
You can also turn on/off individual components by checking/unchecking one or more of the boxes listed in the System Security section.
Application Filtering
The Application Filtering component monitors all applications activity for suspicious behaviour, blocking or allowing certain actions, depending on the level of risk associated with each specific application.
Enable Application Filtering: turns on/off the Application Filtering component.
Access rights for applications
- to computer resources
- to devices
- to runtime environment
For each type of system resource, you can specify how the Application Filtering should operate. The available choices are:
By the rules: the applications monitoring will be performed according to the Application Filtering rules.
Allow: the applications will access the specified system resource without any restrictions.
Settings: click on the Settings menu item to open the Rules settings window. From there you will be able to customize the rules for Application Filtering and edit both the lists of monitored resources and devices.
Clicking on the Settings… button will bring up the same configuration window.
For more details on how to properly configure the Application Filtering component, please refer to this topic.
Firewall
The Firewall component monitors network traffic, allowing or denying connections for any application and filtering data packets according to customizable rules.
Enable Firewall: turns on/off the Firewall component.
Click on the Settings… button to open the Rules settings window. From there you will be able to customize the rules for Application Filtering, the resources monitored by the Firewall component, the rules for Network packages and the list of Network connections.

For more details on how to properly configure the Firewall component, please refer to this topic.
Proactive Defense
The Proactive Defense component checks applications for suspicious behaviour like, for example, key logging activity or hidden drivers installing.
When the Proactive Defense detects a program that is trying to record the keystrokes entered on the keyboard, or to copy itself to the start-up folder or to perform any action similar to those commonly performed by malicious software, it blocks such actions (or, if you unchecked the Select action automatically box in the Protection settings window, it displays a warning message prompting you to allow or deny).
Enable Proactive Defense: turns on/off the Proactive Defense component.
Settings: click on the Settings… button to display the Proactive Defense settings window.

If you want to exclude one or more of the listed events from being detected, just uncheck the desired box. For security reasons, the detection of Trojans, Worms and P2P worms cannot be disabled.
Do not notify about detection of suspicious activity for digitally signed applications, or for applications described in the database of known software: if this box is checked, any suspicious actions performed by well known or digitally signed software will not be reported.
