Until the last update, which was crashing my system, I found TF to be a pretty decent app. It was quite and didn't seem to hinder performance at all. Well after I uninstalled it, and enabled the Defense+ feature in the Comodo firewall, I found it to be a very peaceful app also, although admittedly having enough features to tweak that it would confuse bill gates. Now that they've "fixed" TF I'm tempted to try it again. All these toys are just to much of a temptation!
