Jetico Personal Firewall - Firewall protects your computer while online
Jetico Personal Firewall protects your computer from unwanted hacker's attacks from outside
as well as from malicious programs "living" secretly inside your computer's memory and hard drive. Three levels of protection are included: low-level network packets filtering, application-level network events filtering and filtering of user-level process activity. Jetico Personal Firewall checks every packet that comes in or out of your computer.
