It caught my attention earlier this year by some posters on this forum. I still use Outpost 2009 Free firewall along with Avira for protection. If the resources used for Morro are on the light side, it could be a viable alternative to the many free AV and Firewall products out there. Both of the products I use are really good and don't use much memory or resources. I'll stay with what I got...for now.
