I'm re-thinking my security set-up & need some advise. How important is a HIPS type program? If I were to use Look N Stop firewall & NAV 2009 or Avira, would that be an safe system? Alot of firewalls & some AV's have a HIPS built in. Would Online Armor with it's built in HIPS cause problems with NAV 2009 which I think has some kind of HIPS built in? Sorry to be jumping around, I'm just trying to understand the different ideas about security.
