Hi,
I posted this on ARS forum, might as well you see it too. I just saw this free product that i think is interesting:
https://www.prevx.com/homeoffice/pre.../prevxhome.htm
I got it home, and it stopped some crap that goes over the firewall and the Norton, today...so i was really impress. And it use a very different technic to filter everything, and i must say, i think we are looking at the future with this one.
Take a look and try it if you want.
