3B Personal Firewall Pro 06.26.02

This program prevents unauthorized operations and data loss. It blocks access to specific computers, local ports, and remote ports, and it blocks unsolicited content like pop-up advertisements. If a computer tries to connect to a series of ports on your computer, this program recognizes it as a port scan, which is a common method of finding weaknesses to attack. It also detects attempts to connect to ports used by remote-access Trojan horse programs and local software.
