i need to have firewall so

can i install Comodo Internet Security with nod antivirus

or it will be conflicting cos it not only firewall

i need it to have wi-fi protaction

or go with comodo firwall only with nod

 

Yes.

I have installed them both (EAV4.2.67.10 and COMODO 5.0.162636.1135 Firewall and Defense+) and they work together well

 

What functions does CIS have in it (if any) that overlap with NOD32?

Nod 32 has:

1) AV and 2) ASW
3) Real Time File Protection
4) Email Client Protection
5) Web Access Protection (including blocking by ip or site)

 

Yes that you can do. Or use the in-built Windows firewall.

 

use comodo firewall pro and nod32 and you are good to go!
