I use Agnitum Outpost free firewall on a home network of three computers connected to the newt via at ADSL router.
I know there is a new, paid for version of Outpost and Agnitum says the version I have offers only basic protection.
But I reckon it does all I need. Am I putting my machines at risk?
I also use Spybot S&D; Adaware, Spyware blaster and popup/spam control via Firefox and Thunderbird.
I also have the same setup on a laptop that I sometimes connect to the network so I can use ADSL and sometimes use its internal dial-up modem.
