I did a small test of TF with 5 new malware and exploits. TF blocked them all. It seems TF is quite interesting though not needed by me. Some questions (I'm thinking of various setups for others): 1) Is TF still a CPU hog? 2) Does it work well with Comodo firewall? 3) Does it work well with Kerio firewall? 4) Does it work well with Avira Antivir?
