Hello - I am currently a NOD32 AV user who's subscription is about to run out. I currently run NOD32 with Comodo free firewall, and my computers run beautifully. But Esset is having a special offer on their page that would allow me to purchase the 3 licence Smart Security for cheaper than the cost of just NOD32. My question - can I install Smart Security with the firewall off and continue to use Comodo? I am concerned about some negative reviews and performance tests for the Esset firewall. Thanks.
