Another endorsement for Comodo Personal Firewall here - have had experience w/~7 or 8 different firewalls over the last ~4 yrs & nothing else really compares. Comprehensive control, essentially glitch free, as easy or as complex to use as you want, & it (also Jetico, but it's significantly more difficult to use) blows away all competition @ any price (& it's free). I love this firewall!
Also gotta highly recommend Spyware Terminator - between it & Comodo, I've never felt more informed or secure.
(Sorta wondering why you chose AVG instead of AntiVir - I realize that people like AVG's GUI, but AntiVir has offered better protection, certainly over the past year or so, & it's not that difficult to figure out. The only complaint peolple have w/it is that the updates can take forever but that's no problem @ all provided you do it while most of Europe is asleep.)
Cool idea but unfortunately I suspect that the people who need a prg like this to motivate themselves to do some necessary DL'ing will probably also need some help setting things up. It'll be interesting to see what kind of response it receives tho (I could easily be wrong).
