Hi, 
                It seems that windows firewall default settings do allow a kind of leak that may be vulnerable to attacks.
                  It is also very tough to actually configure the firewall , by choosing while and black list.
                   It is said that zone alarm free is some what better configured to prevent data leak .
                   can i use this tool free with windows firewall. Will it disable the windows firewall, if i use the zone alarm? please your opinion
