Starting with Windows Vista Service Pack 1 and Windows Server 2008, the new Windows Filtering Platform (WFP) architecture is used to check network communication. Since the WFP technology uses special monitoring techniques, the Browsers section is not available.
Because of the enormous amount of malicious code circulating the Internet, safe Internet browsing is a very important aspect of computer protection. Web browser vulnerabilities and fraudulent links help malicious code enter the system unnoticed which is why ESET NOD32 Antivirus focuses on web browser security. Each application accessing the network can be marked as an Internet browser. The checkbox is tri-state:
Unticked- communication of applications is filtered only for specified ports
Ticked - communication is always filtered (even if a different port is set)
Marked with cross - communication of applications marked with cross is not filtered at all
