Dr.Web Firewall in the real time mode creates rules for applications running in the system but are not on its list. Therefore, you must create rules for such applications when they attempt to connect to the network for the first time. A connection request is issued for specific ports and protocols utilized by the application. You can allow all the requested connections, a connection only for a specific protocol and port, or block the connection. Once the rule is created, the firewall handles requests according to the rule and no longer gives out messages regarding application's network activity to the user.
The predefined database contains rules for the most popular programs, as well as all Windows system services and applications. The database is updated on a regular basis.
