Norton Firewall Settings In NIS 2010

hi

 

i would like to know firewall settings.

 

i want to configure NIS like normall firewall i.e it should ask me whether i want to allow a program to access net (also save as option so it dont ask me evrytime )

 

my main motive is to prevent trojan infection since if we crypt trojan and it escapes av detection then even during that if it tries to access net then firewall asks that " program is accessing net"... so i can still deny deny and prevent infection .

 

( eg: once trojan passed av but comodo firwall detected and asked me about programm accesing )

 

so how do i configure norton firewall like that as i dint see such options

 

thx
