Comodo .... Zonealarm pasts its golden era, now its comes with adware also, Privatefirewall is good, but for them only who knows how to use it and configure it. Noob like me prefer to stay with Comodo, this CIS version didn't make any problem with me yet... didn't configure anything manually, running smoothly with Avira...
Dont know how Online Armour is doing now, but used some years ago, not bad, but faced some problem after months of use, cant remember what was the problem though. May be experience users avoid such problems...
