What's the difference between WebTrap and the Personal Firewall?

PC-cillin's WebTrap protects you against malicious Java and ActiveX programs while still allowing the harmless ones to pass through safely. WebTrap only scans Java and ActiveX programs. The Personal Firewall makes your computer's entry points invisible to snooping intruders and creates a barrier between your computer and the network (LAN, Internet). This barrier examines and filters network traffic to your computer. By filtering network traffic, the firewall prevents malicious programs or files from entering your computer.
