During testing, Anti-Porn seemed to be more effective than many of the other parental control applications, at least as default configurations are concerned. But I ran across one feature that's a bit of a nuisance. Anti-Porn is designed to protect children's eyesight by shutting down the monitor for 15 minutes every 45 minutes. Although this feature can be disabled, it is enabled by default.
Most of the applications you mention don't do much more than the controls in my Trend Micro Security Suite, and I suspect the other paid security suites have similar controls built in. Were you intending this list for people that use free anti-virus etc.?
Family Cyber Alert sounds like a key logger, I hope no one ever gets into your computer and hacks it's database.
