Firewall: Network Settings (AVG Business Antivirus)
Firewall is another major component of protection offered in AVG Business Antivirus alongside the Active Protection Shields.
Firewall monitors all network traffic between devices and the outside world to protect you from unauthorized communication and intrusions. The two profiles you can assign to defined networks are:
- Private (Trusted)—Provides a lower level of security
- Public (Not trusted)—Provides a higher level of security
We recommend you apply the Public profile to all networks that are not your private network, such as when you connect to the Internet in a café or at an airport. Network profiles are one of the rule matching attributes, meaning rules for private profiles are not active when connected to a network classified as public and vice versa. Rules can be set to only apply to one profile, or both.
Any networks your device connects to that are assigned specific profiles will be listed in the List of Network Profiles in the UI. Navigate to Menu ▸ Settings ▸ Full Protection ▸ Enhanced Firewall.
Show notification about newly created 'allow' rules: this option will display pop-up notifications when AVG allows or blocks a new communication path.
Internet Connection Sharing mode: this option will allow a trusted user to connect to the internet through your PC and/or connect to devices connected to the internet via your PC. This opens additional ports, which could be a security concern.
Enable automatic port scan detection: this option will allow the Firewall to detect port scan attempts, and automatically blacklists any IP addresses trying to scan the network.
