Ive been seeing alot of people using it. I was wondering about a few things before I make the switch from NOD32. How is it with system resources? When I installed a free version on my moms business laptop it seemed to lag even with pretty decent system resources. My laptop is slightly faster than hers was when she had it. How is the detection rate? And what AV database does it use? Will it play nicely with Comodo Firewall and Defense + enabled?
