How does AVS Firewall Defend the Computer?

AVS Firewall provides the solid defense of your system stability through:

Network protection. AVS Firewall works in both directions. That means the program intercepts the outbound connections initiated by applications on your computer and the ones which income to it i.e. the inbound. When a connection is intercepted AVS Firewall asks you whether to allow or forbid it, all your decisions can be saved as permanent rules so to prevent you from taking a decision on the same connection over and over again. In short you have the absolute power over connections, it is optimal because whatever network attack is it can do harm only in case if you allow a dangerous connection. Moreover AVS Firewall automatically beats off the port scanning attacks that both rids of an excess decision-taking on a permission and enhances the security.

Registry protection. AVS Firewall includes the special component Registry Defender that controls any access to the the most critical registry key values initiated by applications on your computer. The component works from the principle of one-time permisson. That means you should give a permission again as any attempt to modify the controlled registry key values occurs, no matter if the same attempt occurred earlier and what permission you gave it. In other words each new or newly initiated modification try awaits a permission given afresh:

The solid arrows show the inbound and outbounds connections or an attempt to modify the controlled registry key value and dashed ones simulate allowing or forbidding to establish connections or change the regisry key value i.e a certain decision taken by the user.
